Re: Figuring out for-group-by

I am running into trouble doing a transform with for-group-by. I am currently running Saxon 7.9.1 and am in the process of upgrading to 8.0. I thought I would post what I am up to in case my approach is wrong.

I have an XML file that looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<plist version="1.0">
<dict>
<key>Major Version</key><integer>1</integer>
<key>Minor Version</key><integer>1</integer>
<key>Application Version</key><string>4.6</string>
<key>Music Folder</key><string>file://localhost/Volumes/120%20GB/Music/iTunes/iTunes%20Music/</string>

   <key>Library Persistent ID</key><string>4AB531F8615308F0</string>
   <key>Tracks</key>
   <dict>
       <key>35</key>
       <dict>
           <key>Track ID</key><integer>35</integer>
           <key>Name</key><string>Last Time</string>
           <key>Artist</key><string>Fuel</string>
           <key>Album</key><string>Something Like Human</string>
           <key>Genre</key><string>Rock</string>
           <key>Kind</key><string>AIFF audio file</string>
           <key>Size</key><integer>39233574</integer>
            <!-- more key-value pairs -->
       </dict>
        <!-- more dict groups -->
   </dict>
</dict>
</plist>
