All text in an XML document will be parsed by the parser.
Only CDATA section, the text will be ignored by the parser.
PCDATA - parsed character data
XML parsers normally parse all the text in an XML document.
When an XML element is parsed, the text between the tags it will be resolved:
Parser did so because XML elements can contain other elements, as in this instance, where <name> element contains two other elements (first and last):
The parser will break it down into sub-elements like this:
Parsed character data (PCDATA) is a term used in the text data in the XML parser.
CDATA - (unresolved) character data
The term CDATA is text data should not be parsed by the XML parser.
Like "<" and "&" character in the XML element is illegal.
"<" Will generate an error because the parser will interpret the character as the start of the new element.
"&" Will generate an error because the parser will interpret the character as the start character entities.
All content CDATA section will be ignored by the parser.
CDATA part by the"<! [CDATA [" Start by "]]>"End:
if (a < b && a < 0) then
In the example above, the parser will ignore CDATA section all content.
Notes on CDATA section:
CDATA section can not contain the string "]]>." It does not allow nested CDATA sections.
Marks the end of a CDATA section. "]]>" Can not contain spaces or line breaks.
