Regex for path like string

Question

I need to validate that strings has the following pattern:

component/1.2/text
component/1.2.3/othertext
component/1.2.32/text
component/10.21.32/yetanothertext

So always contains two path separators, starts with component followed by major.minor or major.minor.bug and ends with some text.

Any suggestion for a regular expression that can be used to discard anything NOT following the above pattern, e.g.:

component/4/base
comp/4/samples
...

/^component\/\d+(?:\.\d+){1,2}\/\w+$/ ... regex101.com/r/aE8cP4/1 — Pranav C Balan

Try this regex. ^component\/\d+(?:\.\d+){1,2}\/\w+

Here's a visualization.

0

and another soultion:

component/([\d\.]{1,2})/\w+

Or you can try also with {0,1}, not {1,2}
