I'm having trouble with the following. Let's say I have a soap message:

<soapenv:Body xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
 <myResponse xmlns="http://whatever">
  <ns1:ObjectReturn xmlns:ns1="whatever">
   <ns1:somefield>true</ns1:somefield>
   <ns1:collection>
    <ns2:SomeObject xmlns:ns2="whatever">
     <ns2:fieldA>2</ns2:fieldA>
     <ns2:rank>2</ns2:rank>
    </ns2:SomeObject>
    <ns2:SomeObject xmlns:ns2="whatever">
     <ns2:fieldA>1</ns2:fieldA>
     <ns2:rank>1</ns2:rank>
    </ns2:SomeObject>
   </ns1:collection>
  </ns1:ObjectReturn>
 </myResponse>
</soapenv:Body>

and I have a variable:

<xsl:variable name="myVar" select="*[local-name()='collection']/*[local-name()='SomeObject']/*[local-name()='fieldA']"/>

this returns me the value of fieldA in the first occurrence of SomeObject. Now to refine it, I want to get the same value but only in the occurrence where rank = 1. How do I do that?

Thanks in advance

If you were using conventional QName-based paths, it would be

ns1:collection/ns2:someObject[ns2:rank=1]/ns2:fieldA

You can translate that back into your local-name predicates if you wish.
