NAME

       XML::DOM::CDATASection - Escaping XML text blocks in XML::DOM

DESCRIPTION

       XML::DOM::CDATASection extends XML::DOM::CharacterData which extends XML::DOM::Node.

       CDATA sections are used to escape blocks of text containing characters that would otherwise be regarded
       as markup. The only delimiter that is recognized in a CDATA section is the "]]>" string that ends the
       CDATA section. CDATA sections can not be nested. The primary purpose is for including material such as
       XML fragments, without needing to escape all the delimiters.

       The DOMString attribute of the Text node holds the text that is contained by the CDATA section. Note that
       this may contain characters that need to be escaped outside of CDATA sections and that, depending on the
       character encoding ("charset") chosen for serialization, it may be impossible to write out some
       characters as part of a CDATA section.

       The CDATASection interface inherits the CharacterData interface through the Text interface. Adjacent
       CDATASections nodes are not merged by use of the Element.normalize() method.

       NOTE: XML::DOM::Parser and XML::DOM::ValParser convert all CDATASections to regular text by default.  To
       preserve CDATASections, set the parser option KeepCDATA to 1.
