/**
|
|
* 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.
|
|
* <p>The <code>DOMString</code> attribute of the <code>Text</code> 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.
|
|
* <p> The <code>CDATASection</code> interface inherits from the
|
|
* <code>CharacterData</code> interface through the <code>Text</code>
|
|
* interface. Adjacent <code>CDATASection</code> nodes are not merged by use
|
|
* of the <code>normalize</code> method of the <code>Node</code> interface.
|
|
* Because no markup is recognized within a <code>CDATASection</code>,
|
|
* character numeric references cannot be used as an escape mechanism when
|
|
* serializing. Therefore, action needs to be taken when serializing a
|
|
* <code>CDATASection</code> 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.
