::class xmlCDATASection public subclass xmlText

CLASS: xmlCDATASection

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 cannot be nested. Their primary purpose is for including material such as XML fragments, without needing to
escape all the delimiters.

The xmlCharacterData data attribute 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 from the xmlCharacterData interface through the xmlText interface. Adjacent
xmlCDATASection nodes are not merged by use of the normalize method of the xmlNode interface.

No lexical check is done on the content of a CDATA section and it is therefore possible to have the character sequence
"]]>" in the content, which is illegal in a CDATA section per section 2.7 of [XML 1.0]. The presence of this character
sequence must generate a fatal error during serialization.

Note: Because no markup is recognized within a xmlCDATASection, character numeric references cannot be used as an
escape mechanism when serializing. Therefore, action needs to be taken when serializing a CDATASection with a
character encoding where some of the contained characters cannot be represented. Failure to do so would not produce
well-formed XML.

One potential solution in the serialization process is to end the CDATA section before the character, output the
character using a character reference or entity reference, and open a new CDATA section for any further characters in
the text node. Note, however, that some code conversion libraries at the time of writing do not return an error or
exception when a character is missing from the encoding, making the task of ensuring that data is not corrupted on
serialization more difficult.
