RE: [xsl] Using xsl:sort to sort child elements

["Michael Kay" <mhk@xxxxxxxxx>]

By the time you are processing an Address, it's too late to sort the
addresses. When you write

<xsl:template match="EntryData/Applicant/Address">
  <xsl:copy>
    <xsl:apply-templates> 
     <xsl:sort select="ZipCode"/>
   </xsl:apply-templates> 
  </xsl:copy>
</xsl:template>

the apply-templates is selecting the children of the Address, and
evaluating child::ZipCode for each one: but the nodes being sorted are
Type, City, and ZipCode nodes, and none of these has a ZipCode child.
You need to sort the addresses at the point where you are processing the
Applicant.
