Hi Will,
Not sure if this is what you want - but try...
== XSL ==========================================
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:param name="filterparam"/>
<xsl:variable name="ifilter"
select="//person[string-length($filterparam) = 0] |
//person[string-length($filterparam) != 0][cat = $filterparam]"/>
<xsl:template match="/">
<table>
<xsl:for-each select="$ifilter">
<tr>
<td><xsl:value-of select="cat"/></td>
<td><xsl:value-of select="dog"/></td>
<td><xsl:value-of select="fish"/></td>
</tr>
</xsl:for-each>
</table>
</xsl:template>
</xsl:stylesheet>
== end of XSL ===================================
Hope this helps

okay, here is my attempt...not working...very frustrating.
my error: Can not convert #STRING to a NodeList!
