I'm using IE6 & MSXML to transform,sort and count 2 separate xml docs,

As a beginner, I obviously have understood something wrong, I'm using
the so-called "Muenchian method" here (...wtg for the XSLT 2.0 to MSXML)

The Muenchian method works only in a single document context.



I've posted before about using variable-based grouping across 
multiple documents:



  http://www.biglist.com/lists/xsl-list/archives/200410/msg00412.html



In our hands-on training for XSLT 1.0 (next one in less than two 
weeks) we cover three ways of doing grouping:  axis-based, key-based, 
and variable-based ... each have their place in document 
transformation solutions.  Axis-based is good for the adjacent 
context (hiding adjacent duplicates), key-based is good for a 
document-wide context, and variable-based is good for either 
sub-document context or a multiple-document context.



I hope the answer below helps.
