right padding with zeros

Hi,
 How can i right pad a string with zeroes

if a value of 5 digits obtained is 234 it has to be 23400 and not 00234. Is it
possible in format-number.?
I tried but getting only right padded

See
  http://xml.apache.org/fop/running.html#check-input
for generating the intermediate FO as a file.
