XML char data breaking on HTML entities

adcworks

Hi,

I am parsing an RSS feed using PHP's XML parser stuff. I have the parser working quite nicely but I've noticed that entities in character data do not come out properly, that is, I don't get most of the text for an element containing cdata with entities in it.

One such example would be £ for a UK pound sign. If the cdata has one of these, e.g

<element>Chocolate bars to go up £20 in april!</element>

Then I get out of the characterData($parser, $data) function for $data

#163;20 in april!

So it breaks on the ampersand I suppose. I found like one post on the whole of Google about this but did not really get anywhere.

Your help appreciated

ok, cool, i finally found what the issue with this is. apparently the character data handler function can be called multiple times per tag. therefore a developer should concatenate the cdata in the character data to whatever global cdata store they are using at any particular tag instance.

a 1024 byte limit is also placed on the character data function, so 1024 boundaries will also need concatenation to process all the cdata.

Yep; entities are XML nodes in their own right to allow XML parsers access to them.
