Thanks Joelle
My advice is partially wrong.
I just read an example on p320 of Beginning XSLT by Jeni Tennison that is very similar to your problem.
Apparently disable-output-escaping is not implemented on all XSLT processors. (because it can cause the output to not be well formed XML). The book recommends the following as a different strategy: Instead of wrapping the data in CDATA, use a namespace to distinguish between the wrapper element and the content you're interested in. ie <content> <html:p>This is well-formed XML.</html:p> </content>
But if you don't have the luxury to stop using the CDATA... then I would pre-process.

Hi Joelle,
The problem is that the text inside the CDATA is parsed as character data. It has no structure to it according to the XML parser that is passing the information along to XSLT.
The disable-output-escapting attribute you tried only applies to the output... Your interest is to have the CDATA parsed so that you can process it with XSLT.
I would pre-process the XML and remove the CDATA so that the XML parser has an opportunity to parse the data inside.
I think the reason the CDATA was inserted was for security... So you may want to investigate possible security issues when you strip out the CDATA.

Using xsl 1.0 with php 5.x
I'm trying to consume an atom feed and I'd like to print out the full body of the content. It's wrapped in a CDATA section so I'm having trouble getting it to display correctly. The tags come out escaped despite adding the disable-output-escaping. I've looked via google and not found an answer.
Sites do this so it must be possible somehow. Right? Snippets below Links to a manual to read are fine too.
Thanks! Joelle

My xsl snippet:
<xsl:template match="atom:entry[position() = 1]"> <h3> <xsl:apply-templates select="atom:title"/> <xsl:text> </xsl:text> <span class="feed_posted">Posted on: <xsl:apply-templates select="atom:updated"/></span> </h3> <xsl:value-of disable-output-escapting="yes" select="atom:content"/> </xsl:template>
It generates:
