I have 2 variants of strings:
I need only 'needed part' to be matched.
Left boundary is always dot.
Right boundary is asterisk (if exists) or end of line.
Already tried:
/.*[.](.*)[*].*/ - is working for first case
/.*[.](.*)/ - is working for second case
How to do the same with one regex?
You can use
/\.([^*]+)/
See the regex demo.
Details
\. - a dot([^*]+) - Group 1: any one or more chars other than a *.You can also make sure you get the rightmost match by using .* before the pattern (as in the original regex):
/.*\.([^*]+)/
If supported, you might also use a lookbehind to assert a . to the left.
(?<=\.)[^*]+
The pattern matches:
(?<=\.) Positive lookbehind, assert . directly to the left[^*]+ Match 1+ times any char except * using a negated character class
