[xquery-talk] Looking for an example - calling XQuery 3.0 function module from XSLT 3.0

[Michael Kay]

Here's a very simple test case from my test suite (though it uses XSLT 
2.0 and XQuery 1.0):

test.xsl

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
version="2.0"
xmlns:saxon="http://saxon.sf.net/" xmlns:qf="library.uri">

<xsl:template match="/">
<out>
   <xsl:value-of select="qf:distinct-countries(.)"/>
</out>
</xsl:template>

<saxon:import-query href="test.xq" namespace="library.uri"/>

</xsl:stylesheet>

test.xq:

xquery version "1.0";
module namespace qf = "library.uri";
declare function qf:distinct-countries($root as document-node()) as 
xs:string* {
   distinct-values($root//city/@country)
};

One word of advice, I would advise avoiding use of global variables in 
the query library. There are some unresolved bugs relating to use of 
global variables in separately compiled query libraries.

I would also suggest, if you're having problems, it's best to say what 
you are doing and how it is failing. That way, it's easier to see where 
you are stuck and what information you need to help you move forward. 
It's even possible you've hit a bug - you're a little off-piste when you 
use extensions like this, so the risk of finding bugs is greater.
