Re: [xsl] Newbie Problem

[Mike Trotman <mike.trotman@xxxxxxxxxxxxx>]

I think you're failing to retrieve the <fristName> you expect because 
<xsl:for-each> has changed the current context to be your result-tree 
fragemtn - rather than a node in the document.

One normal solution to this is to define a variable containing a node 
from your input document before you enter the <xsl:for-each> loop.
e.g.
<xsl variable name='docroot' select='/wi:root'/>

and then use this variable to retrieve your desired <firstName>.

                   <td><xsl:value-of select="$docroot/changeLog/log[@id 
= $cID]/@firstName" /></td>

I haven't tried this using a for-each loop on a node-set but it should work.
I'm never sure of the differences in the implementation of node-set in 
different processors.
I have some style sheets using node-set that work fine under some XSLT 
processors - but just throw errors under others.
