Adding leading zeroes to record in xslt

Question

We have a number in XML that can go up to 3 digits in a large XML file that has to be converted to fixed length text using xslt for loading into another system.

I need to pad this with leading zeros to a length of 3 in the output (which is fixed length text)

Examples:

• 1 becomes 001
• 11 becomes 011
• 250 becomes 250

Please help.

Answer 1

format-number($n, '000') should do the trick. Alternatively, substring(string(1000+$n), 2).
