Re: Something similar to managing behavior with a va

Hi Wendell;

Here is what I have now (it doesn't compile because of $cur_path):

<xsl:for-each select="$resultstring[contains($cur_path, 'mtrd')]">
<xsl:sort select="DATA/VERSION/ITEM[@NAME='SCORE']" order="descending"
data-type="number" />
<xsl:variable name="cur_path" select="concat(@PATH, @FNAME)"/>
<xsl:variable name="position" select="position()" />
<xsl:call-template name="showresult">
<xsl:with-param name="position" select="$position"/>
<xsl:with-param name="page" select="$page"/>
</xsl:call-template>
</xsl:for-each>

My problem is part of my condition is based on information from the node I'm
on while processing.
Is it possible to loop through and create a node set of the nodes that meet
the condition and than loop through again writing them? Is there a better
way?

Thanks,

Luke
