[xquery-talk] if statements within where clauses?

[Jonathan Robie]

Ooops, I forgot the "then" keyword:

   where contains($text, $keyword)
     and if ($var ='all')
           then
             $entries//classcode = $region
           else
             true()

But you probably caught that error ;->
