Interface CDATASection
- public interface CDATASection
- extends Text
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 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 from the
CharacterData
interface through the Text
interface.
Adjacent CDATASection
nodes are not merged by use of the
normalize
method of the Node
interface. Because no
markup is recognized within a CDATASection
, 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.
