Re: [Exist-open] FLWOR into XIncludes

My simple test-case works perfectly: --------- xquery version "3.0"; declare default element namespace "http://www.w3.org/1999/xhtml"; import module namespace util="http://exist-db.org/xquery/util"; declare namespace xi="http://www.w3.org/2001/XInclude"; import module namespace xmldb="http://exist-db.org/xquery/xmldb"; let $testContents := <html> <body> <p>Para 1</p> <p>Para 2</p> <xi:include href="http://hotpot.uvic.ca/"> <xi:fallback><div xmlns="http://www.w3.org/1999/xhtml">Unable to find xincluded content.</div></xi:fallback> </xi:include> </body> </html>, $storedDoc := xmldb:store('/db/test/', 'text.xml', $testContents, 'application/xml'), $test2 := <html> <body> <xi:include href="{$storedDoc}"> <xi:fallback><div xmlns="http://www.w3.org/1999/xhtml">Unable to find xincluded content.</div></xi:fallback> </xi:include> </body> </html>, $test3 := util:expand($test2, "enable-xincludes=yes") return $test3//p -------- Result: <p xmlns="http://www.w3.org/1999/xhtml">Para 1</p> <p xmlns="http://www.w3.org/1999/xhtml">Para 2</p> So there's obviously some complicating factor in my application. I suspect it's something to do with using relative paths; the relative path in the href attribute in the XInclude is relative to the containing document, but perhaps the execution context is the location of the XQuery document that's doing the work.
