regex parse multiple expressions

Question

I have a requirement to parse part of url with multiple expressions using regex, expressions are like /abc/def (or) /z/a (or) /v/g. I have a regex that satisfies single expression, but not sure how to do for multiple expression.

(?<volga>.+?\/abc\/def.+?)

volga is a named capturing group. Above regular expression satisfies anything before /abc and anything after /def, the same way url also has /z/a and /v/g. This is kind of either /abc/def/ or /z/a or /v/g can exist in url. How to write a regular expression that checks for all of above expressions.

Examples of url:

/api/com/abc/def/710660716/847170/

/api/com/z/a/

Do you know the regex OR: '|' Try inserting that in your regex. — Poul Bak, Mar 22 '20 at 23:00
I misunderstood the question. I thought you were looking for multiple matches, not matching multiple patterns. — Barmar, Mar 22 '20 at 23:02
```| rex field=requestPath "(?.+?(\/abc\/def) | (\/z\/a) | (\/v\/g.+?)"```, Is this regular expression okay? — Vipul, Mar 22 '20 at 23:17

Maybe this:

(?<volga>.+?\/((abc\/def)|(z\/a)|(v\/g)).*)

Matches any string containing
- abc/def
- or z/a
- or v/g
