HTML::DOM::CharacterData(3) User Contributed Perl Documentation HTML::DOM::CharacterData(3)
 

HTML::DOM::CharacterData - A base class shared by HTML::DOM::Text and ::Comment

Version 0.058

This class provides those methods that are shared both by comments and text nodes in an HTML DOM tree.

The following DOM attributes are supported:
data
The textual data that the node contains.
length
The number of characters in "data".
length16
A standards-compliant version of "length" that counts UTF-16 bytes instead of characters.

substringData ( $offset, $length )
Returns a substring of the data. If $length is omitted, all characters from $offset to the end of the data are returned.
substringData16
A UTF-16 version of "substringData".
appendData ( $str )
Appends $str to the node's data.
insertData ( $offset, $str )
Inserts $str at the given $offset, which is understood to be the number of Unicode characters from the beginning of the node's data.
insertData16
Like "insertData", but $offset is taken to be the number of UTF-16 (16-bit) bytes.
deleteData ( $offset, $length )
Deletes the specified data. If $length is omitted, all characters from $offset to the end of the node's data are deleted.
deleteData16
A UTF-16 version of the above.
replaceData ( $offset, $length, $str )
This replaces the substring specified by $offset and $length with $str.
