XML::DOM::CharacterData - phpMan

NAME
    XML::DOM::CharacterData - Common interface for Text, CDATASections and
    Comments

DESCRIPTION
    XML::DOM::CharacterData extends XML::DOM::Node

    The CharacterData interface extends Node with a set of attributes and
    methods for accessing character data in the DOM. For clarity this set is
    defined here rather than on each object that uses these attributes and
    methods. No DOM objects correspond directly to CharacterData, though
    Text, Comment and CDATASection do inherit the interface from it. All
    offsets in this interface start from 0.

  METHODS
    getData and setData (data)
        The character data of the node that implements this interface. The
        DOM implementation may not put arbitrary limits on the amount of
        data that may be stored in a CharacterData node. However,
        implementation limits may mean that the entirety of a node's data
        may not fit into a single DOMString. In such cases, the user may
        call substringData to retrieve the data in appropriately sized
        pieces.

    getLength
        The number of characters that are available through data and the
        substringData method below. This may have the value zero, i.e.,
        CharacterData nodes may be empty.

    substringData (offset, count)
        Extracts a range of data from the node.

        Parameters: *offset* Start offset of substring to extract. *count*
        The number of characters to extract.

        Return Value: The specified substring. If the sum of offset and
        count exceeds the length, then all characters to the end of the data
        are returned.

    appendData (str)
        Appends the string to the end of the character data of the node.
        Upon success, data provides access to the concatenation of data and
        the DOMString specified.

    insertData (offset, arg)
        Inserts a string at the specified character offset.

        Parameters: *offset* The character offset at which to insert. *arg*
        The DOMString to insert.

    deleteData (offset, count)
        Removes a range of characters from the node. Upon success, data and
        length reflect the change. If the sum of offset and count exceeds
        length then all characters from offset to the end of the data are
        deleted.

        Parameters: *offset* The offset from which to remove characters.
        *count* The number of characters to delete.

    replaceData (offset, count, arg)
        Replaces the characters starting at the specified character offset
        with the specified string.

        Parameters: *offset* The offset from which to start replacing.
        *count* The number of characters to replace. *arg* The DOMString
        with which the range must be replaced.

        If the sum of offset and count exceeds length, then all characters
        to the end of the data are replaced (i.e., the effect is the same as
        a remove method call with the same range, followed by an append
        method invocation).
