regex could simply be something like "(\w+)" if your identifiers are comprised only of "word characters" (letters, underscore) — Pac0

If your identifiers are comprised of word characters only:

this regex works: (?<=id=")\w+(?="). The full match is the id. However, this could cause compatibility issue in Safari, that doesn't support lookbehinds ((?<= ))

Test it on Regex101

You can also use capture groups with id="(\w+)". The only captured group will be the id you're looking for.

FYI. It's better to use capture groups since safari doesn't support lookbehinds.

You can use id="(\w+)" as the regex.
