Regex for leading zeros and exclude normal zeros -

i looking 2 traverse list of alphanumerics this:

0012-0103

i want remove leading zeros keep ones belong given number value.

i have gets zeros:

/0*([1-9][0-9])?0/ 

any suggestions. still review regex documentation.

you can use following:

\b0+ 

see demo

explanation:

• \b word boundary.. check boundaries separated word , non word (digits part of word)
• 0+ match more 1 zeros

therefore, match zeros not in middle..
