Hi..
I am going through following problem.
Let me explain you....
I have to extarct information from the file...
lets file is x.v
module x;
pattern:start
p1;
p2;
endpattern
endmodule
module y;
pattern:xxx
p3;
p4;
endpattern
endmodule
I am extracting information from the file and creating a hash map.
I need to store..
{module name} = pattern content...
here I will be like this
hashmap{x} = p1 p2
hashmap{y} = p3 p4
How cam I do that..........
I am struggling...

Need a stopping condition...
ex:
module m1;
endmodule
module m2;
endmodule
so like
while<fp_ptr> {
if (/module\s*(\w)\)?.*/) {
my moduleName = $1;
}
parse till encounter endmodule... Then start from the beginning.
This condition I want.
}
The file can contain... n module definition.

This smells like a course assignment.
There's nothing hard here.. it's pretty basic parsing.
I doubt anyone here is going to do your homework for you. If you provided code you tried to write that didn't work, we MIGHT help you out if you explain it well and aren't just dumping a bunch of junk.
Otherwise, sorry, but no.

I think I have confused everybody...
Here in short what I want to do...
I want to extract pattern from the file which can come multiple times...
pattern_1 any_thingh
pattern_2:anything /*I want to extract
anything pattern_2 to pattern_3 and store that
anything in a string
pattern_3 */
pattern_4
patten2 - pattern3 can come multiple time inside patten1- pattern2..

The only confusion is you thinking that people are going to write programs for you for free.

Try the free sample chapter of the book Pro Perl Parsing. It will teach you what you need to know.
