Hi Everyone,

I am a Newbie and would like to know how I could do the following regex( really tried for half a day before posting this):

I need to parse a hardware code to pick and choose just the statements starting with "$fwrite(" and that ends with a ";". The coding has new-lines in between those statements, However I want them to be chosen too There are accidental "\n" in between the arguments of $fwrite which should be considered as a single line. When I tried doing : 

#!/usr/local/bin/perl -w
use strict;
open(IN,"<ab.in");
while($_=<IN>)
{
   if($_=~/\$display(.*?);$/i)
   {
     print;
   }
}
close(IN);

I get statements that have nested "fwrite" statements omitted in the o/p.

Eg. For the statement below: 

$fwrite(f,{few parameters},$fwrite(f,{kjg,kk}));
$fwrite(f,koal,jirp);
fwrite(f,jrei,
orowp,jgo);

[download]
the o/p is supposed to be: 
$fwrite(f,{few parameters},fwrite(f,{kjg,kk}));
$fwrite(f,koal,jirp);
fwrite(f,jrei,orowp,jgo);

[download]
But the o/p that my code is producing instead is

$fwrite(f,koal, jirp);

In short, it is not recognizing fwrite statements that either have: a. a '\n' between its arguments b. nested fwrites.

Hope this is clear.. Can anybody please suggest a better solution.

Thanks, Hari
