Hi all!

I'm trying to use the key() function together with <xsl:key> element in the following way: I have the input document:
################################################## ##################
          <A>
             <B>
                <C1 atr1="_10">
                   <D1>name1</D1>
                </C1>
             </B>
          </A>
          ............
          <A>
             <B>
                <C2>
                    <D2>name</D2>
                    <E2>
                       <F2 atr2="_10"/>
                    </E2>
                </C2>
             </B>
          </A>
################################################## ###################

So when I process this document, when I reach <C2>, I need to insert the "name" value that corresponds to the key "_10" from "atr2", which is the one from "atr1" of tag "C1"; so that would be the name from <D1>.

I tried with:
<xsl:key name="id_to_name" match="A/B/C1" use="@atr1"/>
and call it like this:
<xsl:template match="B/C2">
   <myTag>
      <xsl:value-of select="key('id_to_name', @atr2)/D1"/>
   </myTag>
</xsl:template>

but I get no results.

If anybody can help me it would be great.

Best regards,
Fred

The C2 element does not have at attribute called @atr2. You need key(..., E2/F2/@atr2)
