Re: [eXist-TEIXML] passing arguments to XQuery functions

[Christopher T. <chr...@ca...>]

Hi Martin,

I'm not using <listPerson> as I believe <person> can be used directly in 
<particDesc>. Each entry in the annotated bibliography I'm working on is 
about a single author so I'll only have one <person> element per 
header.  An extra slash after the $doc variable doesn't seem to make any 
difference either, unfortunately.

I find I can get the code working in my main query, but as soon as I 
move it to the module and call it using { bibl:dob($doc) } it no longer 
works.  However, functions declared in bibl.xqm do work when they 
contain no XQuery expressions but only HTML and boilerplate text.  This 
leads me to believe there's a problem with passing the argument $doc to 
the function held in bibl.xqm.

This slightly more sophisticated version below returns dates of birth as 
a FLWOR expression within the main query.  But, declared as a function 
in the module and called in the main query it no longer returns anything.

declare function bibl:dob($doc) {
             let $dob := 
$doc/tei:teiHeader/tei:profileDesc/tei:particDesc/tei:person/tei:birth/text()
             let $dod := 
$doc/tei:teiHeader/tei:profileDesc/tei:particDesc/tei:person/tei:death/text()
             let $dob-separator := ' - '
             return
             if (exists($dod)) then (<p>{concat($dob, $dob-separator, 
$dod)}</p>)
             else (<p>{concat($dob, $dob-separator)}</p>)
};

Any other ideas?  Thanks for your help so far.

Cheers,
Chris
