Re: [xsl] recursive counter not incrementing

[Christopher Hansen <chansen1@xxxxxxxxx>]

Ultimately i am trying to check if the items in $s1 can also be found in $s2.  
For example - 
$s1 would consist of 2 items, $s1/item/Milk and $s1/item/Sugar
$s2 would consist of 10 different items, Milk and Sugar are among them.  
I've accomplished this using the for-each loop you suggested, however
i need a way to signal that ALL items have been found after the loop,
and not only some of them.

I'm thinking something like:

<xsl:for-each select="$s1/item[.=$s2/item]">
   <!--now, try to place the items that it found matches for, into a
nodeset and compare it to the original $s1 itemset.  If the results
from the for-each loop and the $s1 itemset contain the same items,
output COMPLETE MATCH-->
       
However, i'm not sure how to accomplish getting every matched item it
finds into a nodeset of some sort that i can use for a comparison
later on.  Any help would be appreciated...I'm a beginner and
frustration is setting in, but so far you guys have helped me a good
deal. Thanks.

Chris
