Remove Cdata from xslt output

In this file:
http://rss.wunderground.com/auto/rss_full/CO/Aurora.xml?units=both
You will see a Cdata section under <description>.
I would like to use all the <description> elements except that one. Can I omit Cdata sections?
This is what I have so far:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="channel">
<xsl:apply-templates select="item" />
</xsl:template>
<xsl:template match="item">
<xsl:apply-templates select="item" />

 <xsl:value-of select="title" /> 
 <xsl:value-of select="description" />
 
</xsl:template>
</xsl:stylesheet>

Could you write me an example using the
http://rss.wunderground.com/auto/rss_full/CO/Aurora.xml?units=both
as your file? The reason I ask is because I am not sure I understand the syntax of [not(*)].

Gertone (Geert Bormans)

joseph,
I don't think not(*) will work because the <img> you are refering to,
is inside the CDATA section and will not be accessed as a child node, but as a "<img ...." text node

if the existence of teh img pseudo tag is a possible trigger
you could use
description[contains(., '<img')]
which is similar to checking for "|"

Bottom line is
- if you can find a trigger inside the text that will tell you not to use that description (eg. teh img pseudo tag or a | or whatever)
you can use the contains() in the test
- if not you will have to preprocess the XML before the parser gets to it

in your code that would mean

replace
<xsl:value-of select="description" />

with
<xsl:if test="not(contains(description, '<img'))">
<xsl:value-of select="description" />
</xsl:if>

if for one reason or another you would like the content of description, but not in its escaped form
you can do this
<xsl:value-of select="description" disable-output-escaping="yes"/>

Okay, I think I understand now.
I would love to split the points between you two if possible. Would that be okay with you guys?

PS: if you don't need to do it in one pass, then you can use XSLT 2.0 both for preprocessing (regex) and processing (xslt), like Geert proposed.

You could use xpath to work around it.

Gertone (Geert Bormans)

I see that the asker has added a suggestion and asks that to be accepted as the solution.
What the asker suggests is NOT a solution to the original question.
His solution requires parsing the XML to allow XPath to access to it, CDATA sections will be long gone then, as has been mentioned before.
The question has been answered correctly and extensively before.
So I DO object to this measure.
