Description

TDOMCharacterData is a TDOMNode descendant that implements the CharacterData interface from the DOM specification. TDOMCharacterData provides properties and methods used to access and manipulate character data in the DOM APIs.

Remark: Methods which alter character data use 0-based offsets; the offset values are converted internally to the 1-based offsets used in FPC / Lazarus.

TDOMCharacterData is the ancestor class for other DOM Node specializations like TDOMText and TDOMComment. TDOMCharacterData is not used directly. Use one of the descendent classes.

Use TDOMCDATASection for the CDATA interface defined in the DOM specification.
