Loop twice, then inside loop select nodes??
If I have a for-each loop that I want to loop through 2 times and then select nodes inside that??

When I try to do this I get error ="cannot select nodes here as the context item is atomic"

I understand the error but was wondering if there was a work around?

xsl:for-each changes the context item. If, within the loop, you want to access the item that was the context item outside the loop, you need to bind a variable before the context item disappears:


<xsl:variable name="c" select="."/>
<xsl:for-each select="....">
    <xsl:value-of select="$c/x/y/z"/>

This applies regardless whether the inner for-each selects nodes or atomic values, but in the case where it selects atomic values there is the advantage that you get an error message.
