VC xml parsing notes

Document directory

• CDATA considerations:

The following are five pre-defined entities in the XML document:

& Lt;	<	Yu no.
& Gt;	>	Yu no.
& Amp;	&	And
& Apos;	'	Single quotes
& Quot;	"	Double quotation marks

The object must start with the symbol "&" and end with the symbol.

Note: Only the "<" and "&" characters are strictly forbidden for XML. The rest are legal. It is a good habit to use entities to reduce errors.

CDATA parts

All content in CDATA is ignored by the parser.

If the text contains many "<" characters and "&" characters-like program code, it is best to put them in the CDATA component.

A CDATA part starts with "<! [CDATA ["Mark start, end with"]> "mark:

<script> <![CDATA[ function matchwo(a,b) { if (a < b && a < 0) then { return 1 } else { return 0 } } ]]> </script>

In the previous example, all texts between CDATA components are ignored by the parser.

CDATA considerations:

CDATA components cannot be nested ). If the CDATA part contains the character "]>" or "<! [CDATA [", which may cause errors.

Note that there is no space or line break between the string "]>.
