## Interface XmlCursor

- All Superinterfaces:
    AutoCloseable, XmlTokenSource
  All Known Implementing Classes:
    Cursor

      public interface XmlCursor
      extends XmlTokenSource, AutoCloseable

  Represents a position between two logical tokens in an XML document.

  The tokens themselves are not exposed as objects, but their type and properties are discoverable through methods on the cursor. In particular, the general category of token is represented by a `TokenType`.

  You use an XmlCursor instance to navigate through and manipulate an XML instance document. Once you obtain an XML document, you can create a cursor to represent a specific place in the XML. Because you can use a cursor with or without a schema corresponding to the XML, cursors are an ideal way to handle XML without a schema. You can create a new cursor by calling the `newCursor` method exposed by an object representing the XML, whether it was parsed into a strong type compiled from schema or an `XmlObject` (as in the no-schema case).

  With an XmlCursor, you can also:

  - Execute XQuery and XPath expressions against the XML with the execQuery and selectPath methods.
  - Edit and reshape the document by inserting, moving, copying, and removing XML.
  - Insert bookmarks that "stick" to the XML at the cursor's position even if the cursor or XML moves.
  - Get and set values for containers (elements and whole documents), attributes, processing instructions, and comments.

  A cursor moves through XML by moving past tokens. A token represents a category of XML markup, such as the start of an element, its end, an attribute, comment, and so on. XmlCursor methods such as toNextToken, toNextSibling, toParent, and so on move the cursor among tokens. Each token's category is of a particular type, represented by one of the nine types defined by the `TokenType` class.

  When you get a new cursor for a whole instance document, the cursor is intially located before the STARTDOC token. This token, which has no analogy in the XML specification, is present in this logical model of XML so that you may distinguish between the document as a whole and the content of the document. Terminating the document is an ENDDOC token. This token is also not part of the XML specification. A cursor located immediately before this token is at the very end of the document. It is not possible to position the cursor after the ENDDOC token. Thus, the STARTDOC and ENDDOC tokens are effectively "bookends" for the content of the document.

  For example, for the following XML, if you were the navigate a cursor through the XML document using toNextToken(), the list of token types that follows represents the token sequence you would encounter.

       <sample x='y'>
           <value>foo</value>
       </sample>

  STARTDOC
  START (sample)
  ATTR (x='y')
  TEXT ("\n ")
  START (value)
  TEXT ("foo")
  END (value)
  TEXT ("\n")
  END (sample)
  ENDDOC

  When there are no more tokens available, hasNextToken() returns false and toNextToken() returns the special token type NONE and does not move the cursor.

  The `currentTokenType()` method will return the type of the token that is immediately after the cursor. You can also use a number of convenience methods that test for a particular token type. These include the methods isStart(), isStartdoc(), isText(), isAttr(), and so on. Each returns a boolean value indicating whether the token that follows the cursor is the type in question.

  A few other methods determine whether the token is of a kind that may include multiple token types. The isAnyAttr() method, for example, returns true if the token immediately following the cursor is any kind of attribute, including those of the ATTR token type and xmlns attributes.

  Legitimate sequences of tokens for an XML document are described by the following Backus-Naur Form (BNF):

       <doc> ::= STARTDOC <attributes> <content> ENDDOC
       <element> ::= START <attributes> <content> END
       <attributes> ::= ( ATTR | NAMESPACE ) *
       <content> ::= ( COMMENT | PROCINST | TEXT | <element> ) *

  Note that a legitimate sequence is STARTDOC ENDDOC, the result of creating a brand new instance of an empty document. Also note that attributes may only follow container tokens (STARTDOC or START)

- - ### Method Detail

    - #### close

          default void close()

      Deallocates resources needed to manage the cursor, rendering this cursor inoperable. Because cursors are managed by a mechanism which stores the XML, simply letting a cursor go out of scope and having the garbage collector attempt to reclaim it may not produce desirable performance.

      So, explicitly disposing a cursor allows the underlying implementation to release its responsibility of maintaining its position.

      After a cursor has been closed, it may not be used again. It can throw IllegalStateException or NullPointerException if used after disposal.

      XmlCursor implements `java.lang.AutoCloseable` and the try-with-resources pattern is recommended.

      Note: Future major release will remove this default implementation.

      Specified by:
        `close` in interface `AutoCloseable`

    - #### dispose

          @Deprecated
          void dispose()

      Deprecated.
      Deallocates resources needed to manage the cursor. For details see `close()`. XmlCursor implements `java.lang.AutoCloseable` and the try-with-resources pattern is recommended.
      See Also:
        `close()`

    - #### toCursor

          boolean toCursor(XmlCursor moveTo)

      Moves this cursor to the same position as the moveTo cursor. if the moveTo cursor is in a different document from this cursor, this cursor will not be moved, and false returned.
      Parameters:
        `moveTo` - The cursor at the location to which this cursor should be moved.
      Returns:
        true if the cursor moved; otherwise, false.

    - #### push

          void push()

      Saves the current location of this cursor on an internal stack of saved positions (independent of selection). This location may be restored later by calling the pop() method.

    - #### pop

          boolean pop()

      Restores the cursor location most recently saved with the push() method.
      Returns:
        true if there was a location to restore; otherwise, false.

    - #### selectPath

          void selectPath(String path)

      Executes the specified XPath expression against the XML that this cursor is in. The cursor's position does not change. To navigate to the selections, use `hasNextSelection()` and `toNextSelection()` (similar to `Iterator`).

      The root referred to by the expression should be given as a dot. The following is an example path expression:

           cursor.selectPath("./purchase-order/line-item");

      Note that this method does not support top-level XPath functions.

      Parameters:
        `path` - The path expression to execute.
      Throws:
        `XmlRuntimeException` - If the query expression is invalid.

    - #### selectPath

          void selectPath(String path,
                          XmlOptions options)

      Executes the specified XPath expression against the XML that this cursor is in. The cursor's position does not change. To navigate to the selections, use hasNextSelection and toNextSelection (similar to java.util.Iterator).

      The root referred to by the expression should be given as a dot. The following is an example path expression:

           cursor.selectPath("./purchase-order/line-item");

      Note that this method does not support top-level XPath functions.

      Parameters:
        `path` - The path expression to execute.
        `options` - Options for the query. For example, you can call the `XmlOptions.setXqueryCurrentNodeVar(String)` method to specify a particular name for the query expression variable that indicates the context node.
      Throws:
        `XmlRuntimeException` - If the query expression is invalid.

    - #### hasNextSelection

          boolean hasNextSelection()

      Returns whether or not there is a next selection.
      Returns:
        true if there is a next selection; otherwise, false.

    - #### toNextSelection

          boolean toNextSelection()

      Moves this cursor to the next location in the selection, if any. See the `selectPath(java.lang.String)` and `addToSelection()` methods.
      Returns:
        true if the cursor moved; otherwise, false.

    - #### toSelection

          boolean toSelection(int i)

      Moves this cursor to the specified location in the selection. If i is less than zero or greater than or equal to the selection count, this method returns false.

      See also the selectPath() and addToSelection() methods.

      Parameters:
        `i` - The index of the desired location.
      Returns:
        true if the cursor was moved; otherwise, false.

    - #### getSelectionCount

          int getSelectionCount()

      Returns the count of the current selection. See also the selectPath() and addToSelection() methods.

      You may experience better performance if you use the iteration model using the toNextSelection method, rather than the indexing model using the getSelectionCount and toSelection methods.

      Returns:
        A number indicating the size of the current selection.

    - #### addToSelection

          void addToSelection()

      Appends the current location of the cursor to the selection. See also the selectPath() method. You can use this as an alternative to calling the selectPath method when you want to define your own selection.

    - #### clearSelections

          void clearSelections()

      Clears this cursor's selection, but does not modify the document.

    - #### toBookmark

          boolean toBookmark(XmlCursor.XmlBookmark bookmark)

      Moves this cursor to the same position as the bookmark. If the bookmark is in a different document from this cursor or if the bookmark is orphaned, this cursor will not be moved, and false will be returned.
      Parameters:
        `bookmark` - The bookmark at the location to which this cursor should be moved.
      Returns:
        true if the cursor moved; otherwise, false.

    - #### toNextBookmark

          XmlCursor.XmlBookmark toNextBookmark(Object key)

      Moves this cursor to the location after its current position where a bookmark with the given key exists. Returns false if no such bookmark exists.
      Parameters:
        `key` - The key held by the next bookmark at the location to which this cursor should be moved.
      Returns:
        The next corresponding bookmark, if it exists; null if there is no next bookmark with the specified key.

    - #### toPrevBookmark

          XmlCursor.XmlBookmark toPrevBookmark(Object key)

      Moves this cursor to the location before its current position where a bookmark with the given key exists. Returns false if no such bookmark exists.
      Parameters:
        `key` - The key held by the previous bookmark at the location to which this cursor should be moved.
      Returns:
        The previous corresponding bookmark, if it exists; null if there is no previous bookmark with the specified key.

    - #### getName

          QName getName()

      Returns the name of the current token. Names may be associated with START, ATTR, NAMESPACE or PROCINST. Returns null if there is no name associated with the current token. For START and ATTR, the name returned identifies the name of the element or attribute. For NAMESPACE, the local part of the name is the prefix, while the URI is the namespace defined. For PROCINST, the local part is the target and the uri is "".

      In the following example, `xmlObject` represents an XML instance whose root element is not preceded by any other XML. This code prints the root element name (here, the local name, or name without URI).

           XmlCursor cursor = xmlObject.newCursor();
           cursor.toFirstContentToken();
           String elementName = cursor.getName().getLocalPart();
           System.out.println(elementName);

      Returns:
        The name of the XML at this cursor's location; null if there is no name.

    - #### setName

          void setName(QName name)

      Sets the name of the current token. This token can be START, NAMESPACE, ATTR or PROCINST.
      Parameters:
        `name` - The new name for the current token.

    - #### namespaceForPrefix

          String namespaceForPrefix(String prefix)

      Returns the namespace URI indicated by the given prefix. The current context must be at a START or STARTDOC. Namespace prefix mappings are queried for the mappings defined at the current container first, then parents are queried. The prefix can be "" or null to indicate a search for the default namespace. To conform with the XML spec, the default namespace will return the no-namespace ("") if it is not mapped.

      Note that this queries the current state of the document. When the document is persisted, the saving mechanism may synthesize namespaces (ns1, ns2, and so on) for the purposes of persistence. These namepaces are only present in the serialized form, and are not reflected back into the document being saved.

      Parameters:
        `prefix` - The namespace prefix for the requested namespace.
      Returns:
        The URI for corresponding to the specified prefix if it exists; otherwise, null.

    - #### prefixForNamespace

          String prefixForNamespace(String namespaceURI)

      Returns a prefix that can be used to indicate a namespace URI. The current context must be at a START or STARTDOC. If there is an existing prefix that indicates the URI in the current context, that prefix may be returned. Otherwise, a new prefix for the URI will be defined by adding an xmlns attribute to the current container or a parent container.

      Note that this queries the current state of the document. When the document is persisted, the saving mechanism may synthesize namespaces (ns1, ns2, and so on) for the purposes of persistence. These namepaces are only present in the serialized form, and are not reflected back into the document being saved.

      Parameters:
        `namespaceURI` - The namespace URI corresponding to the requested prefix.
      Returns:
        The prefix corresponding to the specified URI if it exists; otherwise, a newly generated prefix.

    - #### getAllNamespaces

          void getAllNamespaces(Map<String,String> addToThis)

      Adds to the specified map, all the namespaces in scope at the container where this cursor is positioned. This method is useful for container tokens only.
      Parameters:
        `addToThis` - The Map to add the namespaces to.

    - #### getObject

          XmlObject getObject()

      Returns the strongly-typed XmlObject at the current START, STARTDOC, or ATTR.

      The strongly-typed object can be cast to the strongly-typed XBean interface corresponding to the XML Schema Type given by result.getSchemaType().

      If a more specific type cannot be determined, an XmlObject whose schema type is anyType will be returned.

      Returns:
        The strongly-typed object at the cursor's current location; null if the current location is not a START, STARTDOC, or ATTR.

    - #### currentTokenType

          XmlCursor.TokenType currentTokenType()

      Returns the type of the current token. By definition, the current token is the token immediately to the right of the cursor. If you're in the middle of text, before a character, you get TEXT. You can't dive into the text of an ATTR, COMMENT or PROCINST.

      As an alternative, it may be more convenient for you to use one of the methods that test for a particular token type. These include the methods isStart(), isStartdoc(), isText(), isAttr(), and so on. Each returns a boolean value indicating whether the token that follows the cursor is the type in question.

      Returns:
        The TokenType instance for the token at the cursor's current location.

    - #### isStartdoc

          boolean isStartdoc()

      True if the current token is a STARTDOC token type, meaning at the very root of the document.
      Returns:
        true if this token is a STARTDOC token type; otherwise, false.

    - #### isEnddoc

          boolean isEnddoc()

      True if this token is an ENDDOC token type, meaning at the very end of the document.
      Returns:
        true if this token is an ENDDOC token type; otherwise, false.

    - #### isStart

          boolean isStart()

      True if this token is a START token type, meaning just before an element's start.
      Returns:
        true if this token is a START token type; otherwise, false.

    - #### isEnd

          boolean isEnd()

      True if this token is an END token type, meaning just before an element's end.
      Returns:
        true if this token is an END token type; otherwise, false.

    - #### isText

          boolean isText()

      True if the this token is a TEXT token type, meaning just before or inside text.
      Returns:
        true if this token is a TEXT token type; otherwise, false.

    - #### isAttr

          boolean isAttr()

      True if this token is an ATTR token type, meaning just before an attribute.
      Returns:
        true if this token is an ATTR token type; otherwise, false.

          boolean isProcinst()

      True if this token is a PROCINST token type, meaning just before a processing instruction.
      Returns:
        true if this token is a PROCINST token type; otherwise, false.

    - #### isContainer

          boolean isContainer()

      True if this token is a container token. The STARTDOC and START token types are containers. Containers, including documents and elements, have the same content model. In other words, a document and an element may have the same contents. For example, a document may contain attributes or text, without any child elements.
      Returns:
        true if this token is a container token; otherwise, false.

    - #### isFinish

          boolean isFinish()

      True if this token is a finish token. A finish token can be an ENDDOC or END token type.
      Returns:
        true if this token is a finish token; otherwise, false.

    - #### isAnyAttr

          boolean isAnyAttr()

      True if this token is any attribute. This includes an ATTR token type and the NAMESPACE token type attribute.

        The TokenType instance for the token immediately before the token at the cursor's current location.

    - #### hasNextToken

          boolean hasNextToken()

      True if there is a next token. When this is false, as when the cursor is at the ENDDOC token, the toNextToken() method returns NONE and does not move the cursor.

        true if there is a next token; otherwise, false.

    - #### hasPrevToken

          boolean hasPrevToken()

      True if there is a previous token. When this is false, toPrevToken returns NONE and does not move the cursor.
      Returns:
        true if there is a previous token; otherwise, false.

    - #### toNextToken

          XmlCursor.TokenType toNextToken()

      Moves the cursor to the next token. When there are no more tokens available, hasNextToken returns false and toNextToken() returns NONE and does not move the cursor. Returns the token type of the token to the right of the cursor upon a successful move.
      Returns:
        The token type for the next token if the cursor was moved; otherwise, NONE.

    - #### toPrevToken

        The token type for the previous token if the cursor was moved; otherwise, NONE.

    - #### toFirstContentToken

          XmlCursor.TokenType toFirstContentToken()

      Moves the cursor to the first token in the content of the current START or STARTDOC. That is, the first token after all ATTR and NAMESPACE tokens associated with this START.

      If the current token is not a START or STARTDOC, the cursor is not moved and NONE is returned. If the current START or STARTDOC has no content, the cursor is moved to the END or ENDDOC token.

      Returns:
        The new current token type.

    - #### toEndToken

          XmlCursor.TokenType toEndToken()

      Moves the cursor to the END or ENDDOC token corresponding to the current START or STARTDOC, and returns END or ENDDOC.

      If the current token is not a START or STARTDOC, the cursor is not moved and NONE is returned.

      Returns:
        The new current token type.

    - #### toNextChar

          int toNextChar(int maxCharacterCount)

      Moves the cursor forward by the specified number of characters, and stops at the next non-TEXT token. Returns the number of characters actually moved across, which is guaranteed to be less than or equal to maxCharacterCount. If there is no further text, or if there is no text at all, returns zero.

      Note this does not dive into attribute values, comment contents, processing instruction contents, etc., but only content text.

      You can pass maxCharacterCount < 0 to move over all the text to the right. This has the same effect as toNextToken, but returns the amount of text moved over.

      Parameters:
        `maxCharacterCount` - The maximum number of characters by which the cursor should be moved.
      Returns:
        The actual number of characters by which the cursor was moved; 0 if the cursor was not moved.

    - #### toPrevChar

          int toPrevChar(int maxCharacterCount)

      Moves the cursor backwards by the number of characters given. Has similar characteristics to the `toNextChar` method.
      Parameters:
        `maxCharacterCount` - The maximum number of characters by which the cursor should be moved.
      Returns:
        The actual number of characters by which the cursor was moved; 0 if the cursor was not moved.

    - #### toNextSibling

          boolean toNextSibling()

      Moves the cursor to the next sibling element, or returns false and does not move the cursor if there is no next sibling element. (By definition the position of an element is the same as the position of its START token.)

      If the current token is not s START, the cursor will be moved to the next START without moving out of the scope of the current element.

      Returns:
        true if the cursor was moved; otherwise, false.

    - #### toPrevSibling

          boolean toPrevSibling()

      Moves the cursor to the previous sibling element, or returns false and does not move the cursor if there is no previous sibling element. (By definition the position of an element is the same as the position of its START token.)
      Returns:
        true if the cursor was moved; otherwise, false.

    - #### toParent

          boolean toParent()

      Moves the cursor to the parent element or STARTDOC, or returns false and does not move the cursor if there is no parent.

      Works if you're in attributes or content. Returns false only if at STARTDOC. Note that the parent of an END token is the corresponding START token.

      Returns:
        true if the cursor was moved; false if the cursor is at the STARTDOC token.

    - #### toFirstChild

          boolean toFirstChild()

        true if the cursor was moved; otherwise, false.

    - #### toLastChild

          boolean toLastChild()

      Moves the cursor to the last element child, or returns false and does not move the cursor if there are no element children.

      Moves the cursor to the first attribute of this element, or returns false and does not move the cursor if there are no attributes. The order of attributes is arbitrary, but stable.

      If the cursor is on a STARTDOC of a document-fragment, this method will move it to the first top level attribute if one exists.

      xmlns attributes (namespace declarations) are not considered attributes by this function.

      The cursor must be on a START or STARTDOC (in the case of a document fragment with top level attributes) for this method to succeed.

      Example for looping through attributes:

                XmlCursor cursor = ... //cursor on START or STARTDOC
                if (cursor.toFirstAttribute())

                    do
                    {
                        // do something using attribute's name and value
                        cursor.getName();
                        cursor.getTextValue();
                    }

      xmlns attributes (namespace declarations) are not considered attributes by this function.

      The cursor must be on a START or STARTDOC for this method to succeed.

      Returns:
        true if the cursor was moved; otherwise, false.

    - #### toNextAttribute

          boolean toNextAttribute()

    - #### getTextValue

          String getTextValue()

      Gets the text value of the current document, element, attribute, comment, procinst or text token.

      When getting the text value of an element, non-text content such as comments and processing instructions are ignored and text is concatenated. For elements that have nested element children, this returns the concatenated text of all mixed content and the text of all the element children, recursing in first-to-last depthfirst order.

      For attributes, including namespaces, this returns the attribute value.

      For comments and processing instructions, this returns the text content of the comment or PI, not including the delimiting sequences <!-- -->, <? ?>. For a PI, the name of the PI is also not included. The value of an empty tag is the empty string.

      If the current token is END or ENDDOC, this throws an `IllegalStateException`.

      Returns:
        The text value of the current token if the token's type is START, STARTDOC, TEXT, ATTR, COMMENT, PROCINST, or NAMESPACE; null if the type is NONE.

      Copies the text value of the current document, element, attribute, comment, processing instruction or text token, counting right from this cursor's location up to maxCharacterCount, and copies the returned text into returnedChars.

      When getting the text value of an element, non-text content such as comments and processing instructions are ignored and text is concatenated. For elements that have nested element children, this returns the concatenated text of all mixed content and the text of all the element children, recursing in first-to-last depthfirst order.

      For attributes, including namespaces, this returns the attribute value.

      For comments and processing instructions, this returns the text contents of the comment or PI, not including the delimiting sequences <!-- -->, <? ?>. For a PI, the text will not include the name of the PI.

      If the current token is END or ENDDOC, this throws an `IllegalStateException`.

      The value of an empty tag is the empty string.

      Parameters:
        `returnedChars` - A character array to hold the returned characters.
        `offset` - The position within returnedChars to which the first of the returned characters should be copied.
        `maxCharacterCount` - The maximum number of characters after this cursor's location to copy. A negative value specifies that all characters should be copied.
      Returns:
        The actual number of characters copied; 0 if no characters were copied.

    - #### setTextValue

          void setTextValue(String text)

      Sets the text value of the XML at this cursor's location if that XML's token type is START, STARTDOC, ATTR, COMMENT or PROCINST.

      For elements that have nested children this first removes all the content of the element and replaces it with the given text.

      Parameters:
        `text` - The text to use as a new value.
      Throws:
        `IllegalStateException` - If the token type at this cursor's location is not START, STARTDOC, ATTR, COMMENT or PROCINST.

    - #### setTextValue

          void setTextValue(char[] sourceChars,
                            int offset,
                            int length)

      Sets the text value of the XML at this cursor's location (if that XML's token type is START, STARTDOC, ATTR, COMMENT or PROCINST) to the contents of the specified character array.

      For elements that have nested children this first removes all the content of the element and replaces it with the given text.

      Parameters:
        `sourceChars` - A character array containing the XML's new value.
        `offset` - The position within sourceChars from which the first of the source characters should be copied.
        `length` - The maximum number of characters to set as the XML's new value.

    - #### getChars

          int getChars(char[] returnedChars,
                       int offset,
                       int maxCharacterCount)

      Copies characters up to the specified maximum number, counting right from this cursor's location to the character at maxCharacterCount. The returned characters are added to returnedChars, with the first character copied to the offset position. The maxCharacterCount parameter should be less than or equal to the length of returnedChars minus offset. Copies a number of characters, which is either maxCharacterCount or the number of characters up to the next token, whichever is less.
      Parameters:
        `returnedChars` - A character array to hold the returned characters.
        `offset` - The position within returnedChars at which the first of the returned characters should be added.
        `maxCharacterCount` - The maximum number of characters after this cursor's location to return.
      Returns:
        The actual number of characters returned; 0 if no characters were returned or if the current token is not TEXT.

    - #### toStartDoc

          void toStartDoc()

      Moves the cursor to the STARTDOC token, which is the root of the document.

    - #### toEndDoc

    - #### isInSameDocument

          boolean isInSameDocument(XmlCursor cursor)

      Determines if the specified cursor is in the same document as this cursor.
      Parameters:
        `cursor` - The cursor that may be in the same document as this cursor.

      `a.comparePosition(b) == 0` means a is at the same position as b.
      `a.comparePosition(b) > 0` means a is to the right of b.

      The sort order of cursors in the document is the token order. For example, if cursor "a" is at a START token and the cursor "b" is at a token within the contents of the same element, then a.comparePosition(b) will return -1, meaning that the position of a is before b.

      Parameters:
        `cursor` - The cursor whose position should be compared with this cursor.
      Returns:
        1 if this cursor is after the specified cursor; 0 if this cursor is at the same position as the specified cursor; -1 if this cursor is before the specified cursor.
