It depends what you mean by simple. XSLT has no access to the
declarations in a DTD (or at least the XSLT programmer has no access via
XSLT) so you have to put the information in "by hand" so it's simple but
tedious if the dtd is big

<xsl:template match="*[not(node())]"/> 
zaps all empty elements, except...

<xsl:template match="wibble/[not(node())]">
<xsl:copy-of select="."/>
</xsl:template>

empty elements that are children of wibble, which are copied.
