Selecting models with xi:include and concat()

I need to select a model for xForm upon a parameter.
For that I use
<xsl:choose>
        <xsl:when>
                <xi:include .... />
        </xsl:when>
        <xsl:otherwise>
                <xi:include .... />
        </xsl:otherwice>
</xsl:choose>


Problem sits in <xi:include/>.

Line <xi:include
href="http://wsasd464:8080/exist/rest/db/TBAHtest/aaa.xml"/> works fine,
While <xi:include
href="concat('http://wsasd464:8080/exist/rest/db/','TBAHtest/aaa.xml'"/>
gives me finger in form of:

Exception Class org.orbeon.oxf.resources.ResourceNotFoundException
Message Cannot load
"/PCSentry_DEV/detail/concat('http://wsasd464:8080/exist/rest/db/','TBAH
test/aaa.xml')" with webapp loader

What am I doing wrong?

Thanks,
-Taras

Your href attribute will just be seen as straight text I think, that's
why it's not doing the concat.

You'll (I think) need to use syntax more like the following to build
your xi:include elements, so that xsl processes the concat

<xi:include>
        <xsl:attribute name="href">
                <xsl:value-of select="concat('first bit', 'second
bit')"/>
        </xsl:attribute>
</xi:include>

Or something similar....  But you see the point I'm making hopefully

  I guess you are in an XSLT processor.  The inclusion is
done before passing the script to the XSLT processor.  So
Orbeon try to load two documents (and one with a name
containing the caracters "concat(...") before fireing the
tranformation.

  One solution could be to mak first the transformation,
then post-process the result with the XInclude processor:

    <p:processor name="oxf:xslt">
      ...
        <xsl:transform
            xmlns:xi="http://www.w3.org/2001/XInclude"
            xmlns:xi_="http://www.w3.org/2001/XInclude/Alias"
            ...>
          <xsl:namespace-alias stylesheet-prefix="xi_"
                               result-prefix="xi"/>
            ...
            <xsl:choose>
              <xsl:when>
                <xi_:include .... />
              </xsl:when>
              <xsl:otherwise>
                <xi_:include .... />
              </xsl:otherwice>
            </xsl:choose>
            ...
        </xsl:transform>
      ...
      <p:output name="data" id="tranformed"/>
    </p:processor>

    <p:processor name="oxf:xinclude">
      <p:input  name="config" ref="transformed"/>
      <p:output name="data" ref="data"/>
    </p:processor>

  Not tested.

Or as an alternative, you could skip xi:include altogether.

Use your xsl:choose to assign the name of the document to a variable, eg

<xsl:variable name="include-doc" select="http://wsasd464:8080/exist/rest/db/TBAHtest/aaa.xml"/>

Then use xsl:copy-of and the document() function to insert the document, eg

<xsl:copy-of select="document($include-doc)"/>

Not tested either... but in theory it should work...

Taras,

Your code below is incorrect. In XSLT, attribute values on literal
elements are also literal, so XPath expressions in them won't be
interpreted unless you use attribute value templates, that is you use
curly brackets around:

href="{concat('http://wsasd464:8080/exist/rest/db/','TBAHtest/aaa.xml'}"

Also, note that XInclude processing takes place *before* XSLT
processing. This may or may not be an issue in your case.
