Match line by line

[vincente13]

Hi all..

my $jarFile = "input.jar";
my $content = qx/jar tf $jarFile/;

$content contains the list of files in the jar file.


META-INF/
META-INF/MANIFEST.MF
searchjar/
searchjar/JARFileFilter.class
searchjar/Main.class

In the program, i would like to use regex to match line by line to
check if a specified string exists in it.

my $userInputString = "Main.class";

if(@match = $content =~ m/$userInputString/gs){
print "File is found:\t";
print @match;
}

How can i achieve to print out the result of "searchjar/Main.class"

Appreciate any help

i guess i probably do it this way..
correct me if there is anything wrong

foreach my $item (split(/\n/, $content)) {
if ($item =~ /$userInputString/) {
print "\n\n", $item;
}
}

spilt it with \n and compare it line by line

At least in my experience, you can treat JAR files as ZIP files,
meaning you can use any CPAN modules for ZIP file handling. This may
be easier, since you can then look at the contents rather than scrape
the text output of the jar tool.

actually i was using the ZIP file handling module before that, but
there is a need to install some external modules that need to be
compiled that makes it troublesome..so i guess i fall back onto using
this method instead.
