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 and others do inherit
the interface from it. All offsets in this interface start
from 0.

public java.lang.String getData()
throws DOMException
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.DOMString variable on the implementation
platform.
public void setData(java.lang.String data)
throws DOMException
public int getLength()
data and
the substringData method below. This may have the value
zero, i.e., CharacterData nodes may be empty.
public java.lang.String substringData(int offset,
int count)
throws DOMException
offset - Start offset of substring to extract.count - The number of characters to extract.offset and
count exceeds the length, then all
characters to the end of the data are returned.data, or if the
specified count is negative.
DOMString.
public void appendData(java.lang.String arg)
throws DOMException
data provides access to the concatenation of
data and the DOMString specified.arg - The DOMString to append.
public void insertData(int offset,
java.lang.String arg)
throws DOMException
offset - The character offset at which to insert.arg - The DOMString to insert.data.
public void deleteData(int offset,
int count)
throws DOMException
data and length reflect the change.offset - The offset from which to remove characters.count - The number of characters to delete. If the sum of
offset and count exceeds length
then all characters from offset to the end of the data
are deleted.data, or if the
specified count is negative.
public void replaceData(int offset,
int count,
java.lang.String arg)
throws DOMException
offset - The offset from which to start replacing.count - The number of characters to replace. 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).arg - The DOMString with which the range must be
replaced.data, or if the
specified count is negative.
