Hi, I have a script that takes an xml template, and populates various fields. The order of the elements is important. Anyway, I've been using XML::Smart, and it works like a dream for the most part. The one thing I can't figure out is an easy way to remove empty elements. For example: 

<?xml version="1.0" encoding="utf-8" ?>
<?meta name="GENERATOR" content="XML::Smart/1.6.9 Perl/5.010000 [cygwi
+n]" ?>
<mgdToneUpdate xmlns="http://www.blah.net/telcel/mgdTone" xmlns:blah="
+http://www.blah.com/content" xmlns:jcr="http://www.jcp.org/jcr/1.0">
  <blah:ppuid>blah602527000831</blah:ppuid>
  <thumbnailUpdate/>
  <prelistenUpdate>
    <prelistenMp3ResourceUpdate/>
    <prelistenWavResourceUpdate/>
    <prelistenSmafResourceUpdate/>
    <prelistenAmrwbResourceUpdate/>
    <prelistenRmfResourceUpdate/>
  </prelistenUpdate>
  <premiumUpdate>
    <mp3ResourceUpdate>
      <blah:resourceFilename/>
      <blah:resourceFilename>prelistenMTT00602527000831.mmf</blah:reso
+urceFilename>
      <blah:deviceId/>
      <blah:deviceId>blackberry9000_ver1</blah:deviceId>
      <blah:deviceId>nokia_e71_ver1_subua2</blah:deviceId>
      <blah:deviceId>mot_l6_ver1</blah:deviceId>
    </mp3ResourceUpdate>
    <wavResourceUpdate/>
    <smafResourceUpdate/>
    <amrwbResourceUpdate/>
    <rmfResourceUpdate/>
  </premiumUpdate>
</mgdToneUpdate>

I don't have a dtd file (not really sure how to make one), or if there is some other way to remove the empty elements (but otherwise maintain order of the xml).

Any tips appreciated!
