CharacterData

Synopsis

This interface is a generic one that is extended by Text, CDATASection (which extends Text) and Comment. Any node in a document tree that implements CharacterData also implements one of these more specific types. This interface exists simply to group the string manipulation methods that these text-related node types all share.

The CharacterData interface defines a mutable string. getData( ) returns the “character data” as a String object, and setData( ) allows it to be set from a String object. getLength( ) returns the number of characters of character data, and substringData( ) returns just the specified portion of the data as a string. The appendData( ), deleteData( ), insertData( ), and replaceData( ) methods mutate the data by appending a string to the end, deleting region, inserting a string at the specified location, and replacing a region with a specified string.
