I am using the XSLT processor that .NET uses. I am assuming that it is with 
the latest version of MSXML. When I form the XML string and pass it as an 
argument it seems that the XSLT processor (at least with .NET) 
"automatically" turns it into an XmlDocument. I have been using this for some 
time now, using the expression as part of an XPath expression in the XSLT 
stylesheet:

<xsl:if test="current()/Relationship/Relation/SKU = 
$IdenticalList/root/list/sku">

looping through the values, etc. I hae just run into this problem with the 
function count().

I think what you are describing below is the behavior that I have come to 
rely on. Now I just want to return the count of an XPath expression on that 
node list. Any ideas on how to do that?

Thank you.
