Storing XQuery files as *.xq

Hello,

    I am rather new to OPS, and am trying to send XQuery to an eXist
database. I've gotten everything working by embedding my query in the
'query' input to the 'oxf:xmldb-query' processor, (like in the DMV
example) but what I want to do is store my queries in *.xq files. (in
'model/xqueries/')

I've tried several different things, from xslt to xinclude to identity,
but I can't seem to get it right. Can anyone give me a quick example on
how to read in a *.xq, wrap it in a xdb:query, (the collection is always
the same) and pass it off to the oxf:xmldb-query processor?

Many Thanks,
Daniel E. Renfer (http://kronkltd.net/)

Daniel,

The problem is that a .xq file is not an XML file. Currently, the XML:DB
processors only support XQuery embedded within XML, as you have seen.

One solution would be to update the XML:DB processors to support loading
external queries. I have added a bug for this:

Another, temporary solution would be for you to write some code to
process .xq files. You could use the URL generator to read the file as
text, forcing the content-type to text/plain. Then with the XSLT
processor, prepend "<root>" to the string read, append "</root>", and
use saxon:parse to try to parse the resulting file as XML. Then feed
this enclosed into an <xdb:query> element to the XML:DB processor. Not
trivial, but in principle it should work.
