xtags question with when tag

[Richard Sand <rs...@vgalleries.com>]

Hi all,

I have a simple xtags file that loops through all of the topics and keywords
in an xml help file.

My loop is:

<xtags:forEach select="/help/topic | /help/keyword">

Within this loop, I want to process topics different than keywords.  I
haven't been able to find a way to do this. I tried to do it by testing for
the existence of a child that only exists for a keyword, but the xtag:when
tag doesn't seem to accept wildcards in its test parameter, i.e.:

<xtags:forEach select="/help/topic | /help/keyword">
   <xtags:choose>
      <xtags:when test="keyword_file=*">
         ....
      </xtags:when>
      <xtags:otherwise>
         .....
      </xtags:otherwise>
   </xtags:choose>
</xtags:forEach>

Is there some way to do this?

Thanks!

-Richard

You could try this...

<xtags:when test="keyword_file">

which will match if the current node (a <keyword> or <topic>) has at least
one child <keyword_file> child.

Maybe something like this, iterate through all children of <help> then
branch based on the name

<xtags:forEach select="/help/*">
   <xtags:choose>
      <xtags:when test="name()='topic'">
         ....
        process a <topic>
        ...
      </xtags:when>
      <xtags:when test="name()='keyword'">

         ....

        process a <keyword>
        ...
      </xtags:when>
      <xtags:otherwise>
         .....
      </xtags:otherwise>
   </xtags:choose>
</xtags:forEach>
