Gerben,

I do not know if it is possible with Context. 

But this definitely works with an xsl operation. 

You will need an xsl file like this:

myxslfile.xsl:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

  <xsl:template match="contacts">
  <xsl:for-each-group select="contact" group-by=“contact/@ad">
    <xsl:result-document href="groep-{current-grouping-key()}.xml">
       <contacts>
         <xsl:copy-of select="current-group()"/>
       </contacts>
    </xsl:result-document>
  </xsl:for-each-group>
</xsl:template>
<!-- alleen met Saxon, xslt: versie 2 -->

</xsl:stylesheet>


myxmlfile.xml

<contacts>
<contact>
<name ad=“BAR">John</name>
</contact>
<contact>
<name ad=“BAR”>Gerben</name>
</contact>
</contacts>

Use it like this with saxon (xsl version 2).

saxon -xsl:myxslfile.xsl -s:myxmlfile.xml -o:dummy.xml

This program will generate an empty dummyfile.xml but also xml files, (e.g. BAR.xml) in which it will collect al contact that have @ad=‘BAR', and there will be as many files as you have different values of @ad in your xml file. I am very far from being a specalist on xsl, please refer for further information to xsl forums. Have fun experimenting!

I do this myself and then have a script generate the pdfs.

Hope this helps.

Robert
