Re: newbie xsl:if

I asked a similar question a long time ago (and repeated it when the latest draft came out). I didn't get an aswer then, but was playing with it yesterday and worked out a (trivial) solution. You need to be using something which conforms to the latest draft (or supports variables properly). It is also possible to do something non-standard using the MS processor.

XML Fragment:

-----
<area name="foo">
  <page name="index">
  ...
  </page>
  <page name="foo">
  ...
  </page>
</area>
-----

XSL Fragment:

-----
<xsl-template match="page">

<!-- ** The trick is to set a variable, because you can control the context of the variable when you set it -->
<!-- extract the parents "name" -->
<xsl:variable name="parent" expr="from-parent(node())/from-attributes(name)" />

<!-- Now you can compare the current name with the variable. It doesn't matter what context you use because the variable is now set -->
<xsl:if test="from-attributes(name)=$parent">
Found element .....
</xsl:if>

</xsl-template>

Hope this helps. It certainly should work in the latest version of XT, although I might have made an error when I translated it!

PS I deliberately used the unified (aka long) syntax to make it clear that it worked only with the new version

Hi,

I am trying to learn XSL and have a question:
How would I form a match statement for an xsl:if that would match a
parent's value with the value of the current element?  In other words, I
have a list of sub-elements and want to determine which element has the
same value as the parent.

Thanks,

-James
