Question

I need your help regarding RegexMatch (c#) for file endings:

I need always the number between the extension .html and before the first minus (if you read from right to left)

example:

-213.html
looking for 213

-93-32.html
looking for 32

I tried already -([^\”]*).html, but in the secone example it gives me -93-32 back.

(btw. with my current solution above, i also get the minus, if you know how i can exlude it, please let me know, currently i’m doing a replace “-” with “” afterwards)

Thanks in advance,
Ralf

Answer 1

(\d+)\.html$ should do it. here $ means end of the line anchor.

If you dont want to capture .html use (\d+)(?:\.html)$ ( haven’t tested it though ).

Without anchor, if you read left to right, it would be -(\d+)\.html
