Hi all ,

I know that the rule to sort should be immediately after <xsl:for-each > I am in a situation where i have to read the criteria to sort from some some node in the beginning of XML and based on which i need to make a decision to sortBY corresponding node somewhere down the line....

But as you know the following way doesnt work ...
<xsl:for-each select="somenode">
    <xsl:choose>
       <xsl;when test="$prevnode = 'criteriavalue' ">
             <xsl:sort  order="ascending"  select="node_to_be_sorted"/>
      </xsl:when>
    </xsl:choose>
</xsl:for-each>

Note: dont worry about syntax check on this ...

Is there a way to sneak around and get this Sorting to work based on some criteria ...Or any other work arounds, suggestions?

I think the answer depends on what the tests are (e.g. What is $prevnode?). If your test is based on some value of the nodes selected by the for-each, then you're asking to re-order everything after you get and test the first item. This is not good. The workaround here is to select items based on that value in the original for-each selection.

If, on the other hand, your tests are based on some external value, it's pretty easy. You just create multiple for-each's and only execute the one you need. <xsl:choose> <xsl:when test="$prevnode='criteriavalue1'"> <xsl:for-each select="somenode"> <xsl:sort order="ascending" select="node_to_be_sorted"/> </xsl:for-each> </xsl:when> <xsl:when test="$prevnode='criteriavalue2'"> <xsl:for-each select="somenode"> <xsl:sort order="descending" select="other_node_to_be_sorted"/> </xsl:for-each> </xsl:when> </xsl:choose>
