[xquery-talk] suppressing inter-item spaces

[Priscilla Walmsley]

How about moving the call to string-join out, as in:

<string-join>
{  string-join(
      let $nums := ( "1", "2", "3" )
      for $word at $i in ( "a", "b", "c" )
      return ( $word, $nums[ $i ] ) 
   , "")
}
</string-join>   

Hope that helps,
Priscilla
