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

     4 

     5 =head1 DESCRIPTION

     6 

     7 XML::DOM::CDATASection extends L<XML::DOM::CharacterData> which extends

     8 L<XML::DOM::Node>.

     9 

    10 CDATA sections are used to escape blocks of text containing characters

    11 that would otherwise be regarded as markup. The only delimiter that is

    12 recognized in a CDATA section is the "]]>" string that ends the CDATA

    13 section. CDATA sections can not be nested. The primary purpose is for

    14 including material such as XML fragments, without needing to escape all

    15 the delimiters.

    16 

    17 The DOMString attribute of the Text node holds the text that is

    18 contained by the CDATA section. Note that this may contain characters

    19 that need to be escaped outside of CDATA sections and that, depending

    20 on the character encoding ("charset") chosen for serialization, it may

    21 be impossible to write out some characters as part of a CDATA section.

    22 

    23 The CDATASection interface inherits the CharacterData interface through

    24 the Text interface. Adjacent CDATASections nodes are not merged by use

    25 of the Element.normalize() method.

    26 

    27 B<NOTE:> XML::DOM::Parser and XML::DOM::ValParser convert all CDATASections 

    28 to regular text by default.

    29 To preserve CDATASections, set the parser option KeepCDATA to 1.
