David's solution looks correct to me.

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.
