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.
 public interface CharacterData extends Node {
// Public Instance Methods
void appendData (String arg ) throws DOMException;
void deleteData (int offset , int count ) throws DOMException;
String getData ( ) throws DOMException;
int getLength ( );
void insertData (int offset , String arg ) throws DOMException;
void replaceData (int offset , int count , String arg ) throws DOMException;
void setData (String data ) throws DOMException;
