Hi Mazek,

Maybe something like this? 

 
 % regexp {[/\w]*/(\d+)[._\d]*} /letters/123456_789 unused id 
 1 
 % puts $id 
 123456 
  
 % regexp {[/\w]*/(\d+)[._\d]*} /letters/123456.789 unused id 
 1 
 % puts $id 
 123456 
  
 % regexp {[/\w]*/(\d+)[._\d]*} /letters/123456 unused id 
 1 
 % puts $id 
 123456 
  
 % regexp {[/\w]*/(\d+)[._\d]*} /123456 unused id

In case the regex gets mangled on the forums, try this with the spaces removed:

regexp { [ / \ w ] * / ( \ d + ) [ . _ \ d ] * } $uri unused id

$id will have the value you're looking for.
