Re: concat with unspecific length

Hello
I have following xml bellow and want to concat together as here:
Field1 [from position 1, length varies] + " " [until position 11] +
Field2 [from position 12] + " " [until position 16]+ Field3 [from position 17, length always 10] +
" " [until position 27] + Field4

Input

substring(concat(Field1,'           '),1,11),
substring(concat(Field2,'    '),1,5),
substring(concat(Field3,'          '),1,10),
