Doubt with Regular Expression

Hello everybody!
I have a question with regular expressions; I am trying to obtain the pattern for the examples:

9620314387631 LGF.pdf
9620252215751 NOV.pdf

and I have gotten a match → ^ [9]+\d{12}+[ ]+\w{2}[A-Za-z].pdf (in the web checker regex101.com), but this same pattern is not validated in the web checker regexr.com (error with the + signs; I have tried replacing +[ ]+ with \s , but it does not detect the pattern either. This web always works for me).

It doesn’t work in my project either and I don’t quite understand how to get it.

Thanks in advance!

Hi @mbercianop

Try this regex:
\d+\s\w+.pdf
or
\d{13}\s\w{3}.pdf

Use https://regexr.com/ website for regex.

Hi,

I think the pattern should be as the following.

^9\d{12} +\w{2}[A-Za-z]\.pdf

Can you check if you set .net(C#) mode in regex101?

Thank you all. It was also my lack of knowledge of configuration by not selecting C# (@Yoichi) and multiline (@mkankatala ).

They all work correctly.

Have a great day!!
