Re: [xsl] Trying to check if key is NOT found

I like that! That is very elegant. I'll give that a try!

Thanks,

 Hi,

I have a snippet of xsl to try and look through our document xml, and let me know if a given CrossRefence href attribute does NOT contain an element with a matching Target attribute. The href attribute value is some string of characters, prefixed by a '#'. There are several elements that can have a Target attribute so i wrote my xsl like the following:

 .c9Y6TC { color:#0000ff; }.c49DIK { color:#ac306d; }.c18YC0 { color:#d00020; }.c5M9S0 { color:#000090; }.c69ORU { color:#aaaba0; } <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">

 <xsl:key name="target_ref_key" match="*[@Target]" use="@Target" />

 <xsl:template match="CrossReference">

 <xsl:variable name="unhash_name" select="substring-after(@href, '#')"/>
 <xsl:variable name="matched" select="key('target_ref_key', $unhash_name)"/>
 <xsl:if test="not($matched)">
 No target for:
 <xsl:value-of select="$unhash_name"/>
 </xsl:if>

 </xsl:template>


</xsl:stylesheet>



Assuming the code above is correct why not 


<!-- for the ones that match -->
<xsl:template match="CrossReference[key('target_ref_key',substring-after(@href,'#')]">
 ....
</xsl:template


<xsl:template match="CrossReference">
 <!-- the ones that don't match will fall through to here -->
</xsl:template>

I had read some place on the web that this xsl:if would work to let me know when a key did NOT find any value, but it doesn't seem to be being called. I get the xml file as it is.

Is this the correct way to do this, or is there a better way?

thanks for any help,


Russ
