Hi

I have another query. I am trying to create a generic <xsl:template> which will loop through the entire XML file looking for the word 'ELEMENT' in the attribute rm_class. A portion of the XML file is

------------------------
<archetype xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" archetype_id="Pain.v1draft">
<definition>
<node type="complex object constraint" occurrences="1" id="at0000" rm_class="EVALUATION">
<level>0</level>
<text>Pain</text> <data type="relationship constraint">
<node type="complex object constraint" occurrences="1" id="at0001" rm_class="TREE">
<level>1</level>
<parent>at0000</parent>
<text>Tree</text>
<items cardinality="0..1; ordered" type="relationship constraint">
<node type="complex object constraint" occurrences="1" id="at0003" rm_class="ELEMENT">
<level>2</level>
<parent>at0001</parent>
<text>Pain</text>
<runtime_label type="relationship constraint">
<node type="complex object constraint" occurrences="1" rm_class="CODED_TEXT">
<level>3</level>
<parent>at0001</parent>
<code type="relationship constraint">[ac0001]</code>
<text>Pain</text>
</node>
</runtime_label>
<value type="relationship constraint">
<node type="complex object constraint" occurrences="1" rm_class="TEXT">*</node>
</value>
</node>
</items>
</node>
</data>
</node>
</archetype>
------------------------


The trouble I'm having is in keeping the code independent of the actual file structure. Each XML file that I receive has a slightly different structure which might be Tree, List etc. What I mean is that I will not be able to rely on the XPATH expression '/data/node/items/node' always. I thought I might be able to use the 'following' axis to trace through the XML from the <items> to check all the <node> which have an attribute rm_class="ELEMENT". But thats not working in the <xsl:for-each> construct.

----------------
<xsl:for-each select="following::node/@rm_class='ELEMENT'">
       <xsl:message>Done</xsl:message>
</xsl:for-each>
----------------

All I want is a tree which lists the ELEMENT and its <value>.

How do I go about it sensibly?

Thanks
Rahil
