I am trying to put it in a better way, (I hope :-))
What I am trying to do is check if two patterns could recognize the same
string, for example:
$pattern1=[ag]oprs[cd]x9;
$pattern2=[agpr]oprs;
these two patterns would recognize, both, a set of strings. however
there will be some strings tha

Hello All
I am having problem figuring out how to match two patterns. I have two
pattern and I would like to now if they are the same or if one of them
is a sub pattern of the other. Ej:
$pattern1=[agpr]oprs[cd]x9;
$pattern2=[agpr]oprs;
$pattern3=aors;
$pattern2 is a "subpattern" of $patter

I am trying to extract ".jpg" (subtype of the file) from the string:
c:\my_files\file.jpg
I found the following pattern on the net:
