1regex could simply be something like `"(\w+)"` if your identifiers are comprised only of "word characters" (letters, underscore) – Pac0 Feb 24 '21 at 08:48

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

1FYI. It's better to use capture groups since safari doesn't support lookbehinds. – Hao Wu Feb 24 '21 at 08:58
