XML::DOM::CharacterData - Common interface for Text, CDATASections and Comments
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.
getData and setData (data)
substringData (offset, count)
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.
insertData (offset, arg)
Parameters: offset The character offset at which to insert. arg The DOMString to insert.
deleteData (offset, count)
Parameters: offset The offset from which to remove characters. count The number of characters to delete.
replaceData (offset, count, arg)
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).
