regexp

Hi,

 

 

I'm trying to match via a simple regexp an URI. It can be in a form of:

 

 

/sth/digits

 

/sth/digits.digit

 

/sth/digits_digit

 

 

 

example URI to be matched is: /aaaa/999.8

 

 

I would like to get only "999" of it. I'm trying to use regexp below:

 

 

set matched [regexp {([0-9]+)[\._]{0,1}[0-9]{0,1}$} $url id]

 

 

 

but id is still matched as a 999.8?

 

 

 

Regexp is quite simple, but maybe I misunderstand something. Any hints?
