[xsl] How to select specific nodes using xsl:template match or similar?

["Bhaskar Venkateswaran" <bhaskarji@xxxxxxxxxxx>]

Hi,

I tried posting twice before but couldn't get the code inserted - sorry 
about that.

Here's is a snippet of an XML I have:

<?xml version="1.0"?>
<rep>
 <data name = "20050102">
   <data name = "AAA">
   </data>
   <data name = "BBB">
   </data>
 </data>
 <data name = "20050103">
   <data name = "AAA">
   </data>
 </data>
 <data name = "20050104">
   <data name = "BBB">
   </data>
   <data name = "CCC">
   </data>
 </data>
</rep>

My objective is to choose all first-level data nodes (i.e, nodes with names 
20050102, 20050103 & 20050104 above) within a specified range of dates. In 
other words, what is the best way to, say, choose only the nodes whose 
name-value is between 20050102 and 20050103 (both inclusive). I want to be 
able to choose such nodes at the top-level WITHOUT using a for-each loop. 
That is, I don't want to do something like this because here I am running 
through all nodes that meet my condition as opposed to just selecting all 
such nodes in one query:

 <xsl:variable name="startDate">20050102</xsl:param>
 <xsl:variable name="endDate">20050103</xsl:param>
 <xsl:template match="rep">
   <xsl:for-each select="data">
     <xsl:variable name="date" select="@name"/>
     <xsl:if test="$date &gt;= $startDate and $date &lt;= $endDate">
       <xsl:value-of select="$date"/>
     </xsl:if>
   </xsl:for-each>
</xsl:template>

Hope I am clear. Any help/idea is much appreciated.

Another question: I am trying to use xsl:for-each-group method for the first 
time in an XSL and tried running it using Xalan (C version 1.10.0) with 
Xerces (C version 2.7.0) but I get the following warning:

XSLT Warning: The element xsl:for-each-group is an unknown XSLT element. 
(sample.xsl, line 34, column 71.)

Does it mean I need to upgrade?

Thanks,
Bhaskar
