[oXygen-user] XQuery

[Brett Zamir]

Excellent, thanks... and thanks for the tip about document-uri(). Pretty 
new to XQuery...

One other question if I may...

I'm trying to get a listing of distinct elements across files in a 
directory... and for each distinct value, I'd like to know what one of 
the files was from which that distinct value came (or even better, a 
concatenated list of file names). But since I only want distinct values, 
I don't want to add the filename to the result since it will cause the 
value to not be distinct (though I'd like to store information about the 
filename).

For example, I'd like to search for all values of <myElement> and get 
back something like this as a list of distinct values:

<a>Files: a.xml, q.xml, z.xml:  "Value 1"</a>
<a>Files: b.xml, c.xml:  "Value 2"</a>

or at least get one of the files in which the value is present to show up:

<a>Files: a.xml:  "Value 1"</a>
<a>Files: b.xml:  "Value 2"</a>

I've tried the following, but it causes each value to be repeated, since 
it iterates over each filename listing as a distinct result:

<result>
{
for $b in distinct-values(
    for $a in collection("file:///C:/mypath")
    for $c in document-uri(collection("file:///C:/mypath"))   
    return <a>Files: {$c}: {$a//myElement/string()}</a>
)
return
<b>{$b}</b>
}
</result>

Same result if I try to add $c to the outer level...

thanks,
Brett
