Re: [Qexo-general] Using qexo from Java with unusual input & output formats

[John Ohno]

I'm sorry -- I think my question wasn't clear enough.

I don't want to specify an XML filename. I want to specify an already-parsed DOM Document or Node object -- because my source file is in FastInfoset format, not XML.

While the second part is relatively straightforward, I can't figure out how to convince qexo of the default XML context.

Setting an external input variable (as described in the 27 Sep 2005 message)
seems to work - I just tried it:

$ kawa input=kawa-sources/gnu/xquery/testsuite/bib.xml --xquery -e 'declare variable $input external; doc($input)/bib/book/title'
<title>TCP/IP Illustrated</title><title>Advanced Programming in the Unix environment</title><title>Data on the Web</title><title>The Economics of Technology and Content for Digital TV</title>

(I tried bib.xml in the Kawa source tree.)

Seems to still work.
