[xsl] xpath problem

["Aananth.S" <aananth.solaiyappan@xxxxxxxxxx>]

Hi all,


   We have the following XML fragment.

   <article> som text here    <var name="OKC$S_CURRENCY_NAME" type="S" 
meaning="Currency Name" />  </article>
.........
 <VariablesMetadataVO type="VO" name="VariablesMetadataVO">
   <VariablesMetadataVORow> 
     <ArticleVersionId>101130763</ArticleVersionId>
     <VariableCode>OKC$S_CURRENCY_NAME</VariableCode>
     <VariableType>S</VariableType>
     <DocType>QUOTE</DocType>
     <ViewObjectName>HeaderVO</ViewObjectName>
     <AttributeName>CurrencyName</AttributeName>
   </VariablesMetadataVORow>
................
<HeaderVO>
  <HeaderVORow>
     <CurrencyName>Dollars</CurrencyName>
  </HeaderVORow>
</HeaderVO>
..........


And the following XSL tempalte to match the *var*  tags.

   <xsl:template match="var[@type='S']">
       <xsl:variable name="system" 
select="//VariablesMetadataVO/VariablesMetadataVORow[VariableName=current()/@name]"/>
           <xsl:value-of 
select="//descendant::[name(.)=$system/ViewObjectName]/descendant::[name(.)=$system/AttributeName]"/>                               

     </xsl:template>

the result of applying the template should be some thing like

<article>som text here   Dollars </article>


   The var tag in the article text points to metadata which in turn 
points to the value that has to be substituted in place of the var 
tag.We are currently using the folowing Xpath .. but the parser fails as 
the XPath seems to be malformed. What are we missing here?Any 
suggesiotns for alternative XPaths?any help is highly appreciated.

TIA,
Aananth
