In an RSS feed I notice that some of the post texts are emrbaced in "<![CDATA[" tags and some are not, whats this mean and whats the difference?

Certain characters such as < > ", non english characters and so on confuse the format the RSS feed is produced in, to get everything to ignore these confusing characters, and just accept them as they are, they are put inside a <![CDATA[ ... ]]> block

It's part of the XML Standard if you're wondering... For example, if it wasn't for <!CDATA[ ]> tags - you couldn't embed XML in XML (if that makes sense).

Cheers, not really done alot with XML, some very simple parsing for making pages out of stats given out in XML (like shoutcast) but thats it, but I now wanna utilise the RSS feeds in ibforums to make a few more dynamic sections on my site whilst allowing my users to contibute
