Thanks to Gerrit and Michael I am closer but not quite all the way there yet.

I removed the namespace from the second input file and modified my
apply-templates to:

        <xsl:apply-templates select="$myActionSet/casActions/actionSet[1]"/>


I now get to the actionSet templates.

How do I include the namespace info in the apply-templates call? I don't see
how to do this so that's why I temporarily removed the namespace declaration
from my second input and the declaration for it from my transform.

I'll try adding modes tomorrow to see if that also helps.

Thanks,
  Craig

Hi All,
  I am trying to use the doc( ) function, in XSLT 2.0, to get a second input
file in one of my transforms. The primary input contains an element
"refActionSet" that triggers the logic to fetch the second input.

  Within that template I do:

        <xsl:variable name="myActionSet"
          select="doc('file://sashq/root/pub/pubs_xiswork/sascrs/prod/v16/ecl
ipse/workspace/castest/xml/actions.xml'<file:///\\sashq\root\pub\pubs_xiswork
\sascrs\prod\v16\eclipse\workspace\castest\xml\actions.xml'>)"/>

  Which is successfully getting the second file. I know this because I can
write out to the log the contents of the file and I see the text (no markup).

  But when I try to process this second file using:

        <xsl:apply-templates select="$myActionSet"/>

  My transform fails due to the root element template being executed a second
time. In the root template I setup some java extension processes that can only
be run once so the second time through they cause the transform to fail.

The usual way to solve this problem is with modes. Use

 <xsl:apply-templates select="$myActionSet" mode="actionSet"/>

and add mode="actionSet" to the template rules for the second input file.




  I've tried to solve the problem two different ways, but neither works. First
I tried adding a xpath specification to the doc function so that the returned
XML would start at the element I was interested in, like so:

        <xsl:variable name="myActionSet"
          select="doc('file://sashq/root/pub/pubs_xiswork/sascrs/prod/v16/ecl
ipse/workspace/castest/xml/actions.xml'<file:///\\sashq\root\pub\pubs_xiswork
\sascrs\prod\v16\eclipse\workspace\castest\xml\actions.xml'>)//actionSet[@id=
'abc']"/>

but that caused the function to fail and not fetch the second file.

I think it did fetch the second file. But the path expression //actionSet
didn't select anything, because the actionSet elements are in a namespace, and
you didn't tell it to use a namespace.


I also tried a fragment specification "#actionSet" but this also failed.

  I then tried to kick the second input files root element out of my root
template with a test for ancestor-or-self::casActions and a test for
descendant-or-self::casActions. But neither of these tests worked on the
fetched second file.

Again, that's because you overlooked the namespace declaration.


  Any help would be appreciated in solving this problem.


Note the namespace:
xmlns="http://www.sas.com/xml/namespace/sas_doc_cas_actions-1.0"
