This is actually quite easy. The controller gives you the possibility to pass groups matched by the regexp matcher into the XForms instance. There is an example here:
http://www.orbeon.com/oxf/doc/reference-controller#N10225
So you have to create an XForms model, for example:
<xf:model xmlns:xf="http://www.w3.org/2002/xforms";> <xf:instance> <form> <path/> </form> </xf:model>
Then, pass the instance to your default.xpl:
<p:param name="instance" type="input"/>
Then, you can access to the path with /form/path. What you probably want to do at that point is use the URL generator to create the local URL, for example:
<p:processor uri="oxf/processor/url-generator">
<p:input name="config" href="aggregate('config', #instance#xpointer(concat('oxf:/', /form/path)))"/>
<p:output name="data" id="file"/>
</p:processor>
What I am doing here in the input href is creating a configuration document for the URL generator. You may also do this with XSLT:
<p:processor uri="oxf/processor/xslt">
<p:input name="data" href="#instance"/>
<p:input name="config">
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/">
<config><xsl:value-of select="/form/path"/></config>
</xsl:template>
</xsl:stylesheet>
</p:input>
<p:output name="data" id="url-config"/>
</p:processor>
Which is even easier with XSLT 2.0:
<p:processor uri="oxf/processor/xslt-2.0">
<p:input name="data" href="#instance"/>
<p:input name="config">
<config xsl:version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:value-of select="/form/path"/>
</config>
</p:input>
<p:output name="data" id="url-config"/>
</p:processor>
You can reference the data by referring to href="#file" in a processor input.
If the file is actually an HTML file, you will have to specify the content-type in the generator:
<p:processor uri="oxf/processor/xslt-2.0">
<p:input name="data" href="#instance"/>
<p:input name="config">
<config xsl:version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<url><xsl:value-of select="/form/path"/></url>
<content-type>text/html</content-type>
</config>
</p:input>
<p:output name="data" id="url-config"/>
</p:processor>
You have to use the URL generator because the input href="..." only support statically constructed references to either URLs (e.g. href="oxf:/myfile.html"), or references to processor outputs or pipeline inputs (e.g. href="#my-output").
I hope this helps.
