Hi,
I am trying to output a "select" field from the sample XML below:

<tree>
<option>Ducks</option>
<option>Cows</option>
<option>Sheep</option>
<option>Sheep</option>
<option>Ducks</option>
<option>Cows</option>
<option>Cows</option>
</tree>

I need to group the option values to produce the sample HTML:

<select name=&quot;animals&quot;>
<option>Cows</option>
<option>Ducks</option>
<option>Sheep</option>
</select>

Can anyone help me with the grouping in XSLT?

I have read about Meunchian Grouping, but am confused...

Thanks!

Try this:

<?xml version=&quot;1.0&quot; encoding=&quot;ISO-8859-1&quot; standalone=&quot;yes&quot;?>
<xsl:stylesheet xmlns:xsl=&quot; version=&quot;1.0&quot;>
<xsl:eek:utput method=&quot;html&quot; indent=&quot;yes&quot; encoding=&quot;iso-8859-1&quot; omit-xml-declaration=&quot;yes&quot;/>

<xsl:template match=&quot;/tree&quot;>

<HTML>
<BODY>
<TABLE>
<TR>
<TD>
<SELECT>
<xsl:for-each select=&quot;option&quot;>
<xsl:variable name=&quot;pre-option&quot;>
<xsl:for-each select=&quot;preceding-sibling::*&quot;>
<xsl:value-of select=&quot;concat(.,',')&quot;/>
</xsl:for-each>
</xsl:variable>
<xsl:if test=&quot;not(contains($pre-option, . ))&quot;>
<OPTION>
<xsl:value-of select=&quot;.&quot;/>
</OPTION>
</xsl:if>
</xsl:for-each>
</SELECT>
</TD>
</TR>
</TABLE>
</BODY>
</HTML>
</xsl:template>

</xsl:stylesheet>
