[xsl] Interrogating attributes values to get text (part deaux)

[Charles Flanders <cflanders@xxxxxxxxxx>]

Thank you David for your template.

My apologies for not providing a complete example of my XML. In my quest to be brief, I did give a full picture of my problem. The problem is that there are multiple <nameloc> elements to interrogate. The template you wrote always returns the value for the child of the first <nameloc>. I need to interrogate each <nameloc> id value to find the one that matches @linkend for the current <HYPERTEXT>. I've tried creating a variable using <xsl:for-each>, and then evaluating that against the value of @linkend, but I end with the the first <nameloc> child "P3-11" each time.

My sample should have looked like this:

<document>
  <nameloc id="M05-08.-HT1">
     <nmlist nametype="element" dtdorlpd="BODY" type="PARA0">P3-11</nmlist>
  </nameloc>
  <nameloc id="M05-08.-HT2">
     <nmlist nametype="element" dtdorlpd="REAR" docorsub="APPX-F" elemtype="ROW">item1</nmlist>
  </nameloc>
  <nameloc id="M05-08.-HT3">
     <nmlist nametype="element" dtdorlpd="REAR" docorsub="APPX-G" elemtype="ROW">item2</nmlist>
  </nameloc>
  <nameloc id="M05-08.-HT4">
     <nmlist nametype="element" dtdorlpd="REAR" docorsub="APPX-G" elemtype="ROW">item9</nmlist>
  </nameloc>
  <nameloc id="M05-08.-HT5">
     <nmlist nametype="element" dtdorlpd="REAR" docorsub="APPX-G" elemtype="ROW">item36</nmlist>
  </nameloc>



<STEP>
                   <HYPERTEXT linkend="M05-08.-HT2">Service
                   air cleaner assembly.</HYPERTEXT>
               </STEP>
</document>

Result to be:


<step>Service air cleaner assembly.<link item="item1"></step>

I could use help with problem that I just don't seem to have the 
programming chops to conquer. I don't have template for anyone to 
analyze, I can't seem to get to that state. I'm using XSL 1.0.

Here is my conundrum:

I have an element <HYPERTEXT>, that has an attribute called "linkend". 
The value of "linkend" corresponds to an ID attribute on an element 
further up the tree (preceding). This element is named <nameloc>. This 
element has a child, <nmlist>.  My goal is to convert <HYPERTEXT> to 
<link> (easy enough). But my problem is I can't seem to write an 
expression (xsl:if? xsl:when?) to can go find the <nameloc> element that 
has the corresponding ID, then get the text of <nmlist> as the value of 
an "item" attribute on <link>.

The following are just snippets of XML. The entire tree structure should 
be irrelevant. Also, the <nameloc> and <nmlist> elements are eliminated 
in the results (not converted or output).

Current XML:

<document>
   <nameloc id="M05-08.-HT2">
       <nmlist nametype="element" dtdorlpd="REAR" docorsub="APPX-F"
       elemtype="ROW">item1</nmlist>
   </nameloc>

<STEP>
                   <HYPERTEXT linkend="M05-08.-HT2">Service
                   air cleaner assembly.</HYPERTEXT>
               </STEP>
</document>
The result I need to create is this:

<step>Service  air cleaner assembly.<link item="item1"></step>

How do I write a test will get me text of <nmlist> based on the 
comparison of "linkend" and "id"?

Thanks.

<xsl:template match="HYPERTEXT">
<link item="{key('id',@linkend)/nmlist}"/>
