Formatting string (Removing leading zeros)

Question

I am newbie to xslt. My requirement is to transform xml file into text file as per the business specifications. I am facing an issue with one of the string formatting issue.

Answer 1

As a simple alternative in XSLT 2.0 that can be used with numeric or alpha-numeric input, with or without leading zeros, you might try:

replace( $value, '^0*(..*)', '$1' )

This works because ^0* is greedy and (..*) captures the rest of the input after the last leading zero. $1 refers to the captured group.

Note that an input containing only zeros will output 0.
