Firstly I apologise if this has been asked before, but I cannot work out how to search this mailing list without downloading all the archives first. I am working through the XQuery in 10 minutes tutorial and trying this XQuery:
declare variable $firstName as xs:string external;
<videos featuring="{$firstName}">
{
let $doc := doc('http://www.stylusstudio.com/examples/videos.xml')
    for $v in $doc//video,
       $a in $doc//actors/actor
    where ends-with($a, $firstName)
       and $v/actorRef = $a/@id
    order by $v/year
    return
<video year="{$v/year}">
          {$v/title}
</video>
}
</videos>
It's fine in standalone mode (command line), but I cannot find a way of supplying an external variable in the GUI. Thanks and regards.

You can either specify external variable bindings via the "set" command in the Command mode.. set bindings $firstName=x ..or add a default value to your XQuery expression (this feature is avaiable since XQuery 3.0):
  declare variable $firstName as xs:string external := 'x';
  $firstName
Hope this helps, Christian

Thanks! By the way, is it just me or is there a problem with the results formatting in Firefox 4? (seems fine in IE8)

Hi Mike (cc @ basex-talk), you're right, Firefox seems to have problems rendering the page (Opera and Chrome didn't cause any problem in my ad-hoc test).. Christian
