If the file is fixed in this format, then you could do a check for
)
and write the line after that is found. Then continue with the file. For
example
open IN, "c:/input.txt" || die "Can't open c:/input.txt: $!";
open OUT, ">c:/new.txt" || die "Can't create c:/new.txt: $!";
while (<IN>) {
if (/\s+)/) { # One or more spaces followed by a right bracket
# The line has been found, so print it out and add the
desired text to the new file
print OUT;
print OUT "ABC = 1.1\n";
} else {
print OUT;
}
}
close IN;
close OUT;
You may need to escape the right bracket in the regex. So it looks like
this:
/\s+\)/
I haven't tested it.

Subject: Modifying/Additng text in a file
I have a file whose contents are of the form :
NET_A OUTPUT (
REQUIRED (
_UP %0.093 BR CLK
_DN %0.093 BR CLK
)
)
NET_B OUTPUT (
REQUIRED (
_UP %0.093 BR CLK
_DN %0.093 BR CLK
)
)
I would like to read in this file in and modify the
contents to be as follows :
NET_A OUTPUT (
REQUIRED (
_UP %0.093 BR CLK
_DN %0.093 BR CLK
)
ABC = 1.1 // Insert this expression
)
NET_B OUTPUT (
REQUIRED (
_UP %0.093 BR CLK
_DN %0.093 BR CLK
)
ABC = 1.1 // Insert this expression
)
Any pointer on how to accomplish this would be greatly
appreciated. Could this be accomplished by using a
regexp ?
Thanks
PN
