Re: Insert refs

This is a grouping problem, so use the usual key grouping method:

first key your to elements
<xsl:key mame="to" match="email/to" use="."/>

Then

<xsl:for-each select="email/to[generate-id(.)=generate-id(key('to',.)[1])]">
    <to id="{generate-id()}"><xsl:value-of select="."/></to>
</xsl:for-each>



then


<xsl:template match="to">
 <to ref="{generate-id(key('to',.)[1])}"/>
<xsl:template>



untested...
