<id>. ?<\/id>

but how to find only numbers with hyphens Thanks!

CodePudding user response：

If you want to find only numbers with a hyphen in between:

<id>\K\d -\d (?=<\/id>

Explanation

<id> Match literally
\K Forget what is matched so far
\d -\d Match - surrounded by 1 digits
(?=<\/id> Assert </id> directly to the right
