<xsl:template match="*">
  <xsl:if test="child::* or (string-length(.) != 0)">

</xsl:template>

Is there a simple way to strip empty elements from an XML while still conforming to the requirements of the DTD? I know how to use the string() function to copy only those elements that contain data, but this often removes child elements required by the DTD.

Thanks for your help.
