[xquery-talk] nested if, then, for statements

[Cindy Girard]

Hi ,

  I'm trying to do something like the statement below, but I'm getting
  errors. Do I have the syntax wrong, or do I need to go about it
  completely differently?

  The error is on the 3rd line:
   unexpected token: in [at line ... ]

  Thanks,
  Cindy

   $query := if ($ttl != "")
      then (
         for ($entries in collection('{$collctn}')//TEI.2[. &= '*{$kwds}*' and descendant::head &= '*{$ttl}*'])
            (if $entries/@id = "ppp.00271"
             (
                then ...
             )
             else if $entries/@id = "ppp.00237"
              (
                then ...
              )
              else if $entries/@id = "ppp.00473"
               (
                 then ...
               )
               else
                (
                   ...
                )
              )
              else if (...)
                then ...
              else
                ... ,
