[xquery-talk] function definitions

[Dmitri.Colebatch at toyota.com.au]

hey all,

another question.... hopefully not quite as trivial as the last.

I'm trying to define my own function, and have the following in my header,
however I am getting parse exceptions from the bea weblogic implementation.
Can someone tell me if this is a problem with my code or their
implementation...

define function convertSAPDateTime($dateNode as node(), $timeNode as
node())
      as xs:dateTime
{
      let $dateStr := data($dateNode)
      let $yyyy := xf:substring($dateStr, 1, 4)
      let $mm := xf:substring($dateStr, 5, 2)
      let $dd := xf:substring($dateStr,7, 2)

      let $timeStr := data($timeNode)
      let $HH := xf:substring($timeStr, 1, 2)
      let $mi := xf:substring($timeStr, 3, 2)
      let $ss := xf:substring($timeStr, 5, 2)

      return xf:dateTime(xf:concat($yyyy, '-', $mm, '-', $dd, 'T', $HH,
':', $mi, ':', $ss))
}

the code inside the braces works fine when not defined as part of a
function, but I am getting parse exceptions on the "as" in "$dateNode as
node()".  If I remove the "as node()" then it works fine, however I then
have the wrong type for the data function... I assume could cast it, but as
I understand it the above should work...

fwiw I'm using http://www.w3.org/TR/xquery/#FunctionDefns as my reference.

thanks again for your help.

cheers
