Applying style to CDATA content
Hi guys,
Is it possible to apply templates to data contained within CDATA tags? E.g. if I have to following structure:
Code:
<somedata>
<![CDATA[Here some <link>somewhere</link>]]>
</somedata>
If I would like to apply a template to the <link> tag, would that be possible? If not, can anyone suggest a good work around?
Thanks!

Not in a pure XSLT way as the data in a CDATA section is text, not mark up. That's why people advise against using CDATA in this way. In Saxon you could read the text, use the saxon:parse extension and then pass the value to a function for manipulation, or a named template if you're using version 1.0.

<link> isn't a tag, it's ordinary text. It would be a tag if it weren't in CDATA. The reason (the ONLY reason) for using CDATA is to tell the recipient that everying inside is to be treated as text, not as markup.

That makes sense. However, if I would remove the CDATA tags and put HTML markup in there, like <br />, the markup seems to disappear in the output. ???

Can you show an example of disappearing mark up? You'll need to detail how you're transforming and displaying etc.

If you use <xsl:copy-of> to copy the <somedata> node then it will retain all inner elements. If you are however using <xsl:value-of> then you are making a copy of the textual value of the somedata node, which doesn't include inner markup.

That usually means you used xsl:value-of - but expecting us to debug your code without showing your code is asking for a lot.
