Thanks Mike :)  That's exactly what I needed here :)

The display logic at the two places are little different.  I see (b) and (d)
should work for my situation, I just don't know how to use them :(
I tried to use (d) like the following:

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">
<!-- get a copy of shipto element -->
<xsl:variable name="ShipTo">
<xsl:copy-of select="/pick/addressinfo/shipto"/>
</xsl:variable>
......

IE5 respond with "Keyword xsl:variable may not be used here."  What I did
wrong here?  Also, when I use it, can I just use it like the following?
<xsl:value-of select="ShipTo/firstname" />

Much thanks,
