Match string using regex which includes vertical bar

Question

I have:

|123|456|789|

I can capture only |123| using regex

\|(\d*)\|

But not sure how to capture the full string. I am quite new to this.

I will be thankful for any help

Answer 1

^\|(\d*\|?)*

This should work. Start with vertical bar and repeat numbers and optional vertical bar.

Answer 2

You can do:

^\|[\d|]*

• ^\| matches literal | at start, as | is a Regex token we need to escape it

• [\d|]* matches any number of digits or |, | inside [] is treated literally

From comment, if there must be a | at the end, do:

^\|[\d|]*\|$
