I don't know if anybody has mentioned this before: I disagree, though I thought the same at first when saw Mike's great post ... what you have will be those in $nodes1 not in $nodes2, but not those in $nodes2 not in $nodes1. I figured you would need: ( $ns1[count(.|$ns2)!=count($ns2)]
| $ns2[count(.|$ns1)!=count($ns1)] )to get the true difference as I understand it, that being all nodes in both sets not in the other set. I have an example below. I hope this helps. .......... Ken T:\ftemp>type diff.xsl
