Hello cbtshare, and welcome to the Monastery!

Further to 1nickt’s post, if you open a file with +>> as the mode, the filehandle’s position is set to the end of the file. To read from the beginning, you need to add a seek:

seek XML, 0, 0;

However, as 1nickt says, this won’t solve the problem. You want to update passwords within the file, and appending new data at the end of the file can’t accomplish that.

One approach is to use the core module Tie::File:

use strict;
use warnings;
use Tie::File;

my $filename = ...;

tie my @array, 'Tie::File', $filename
    or die "Cannot tie file '$filename' to array: $!";

for my $line (@array)
{
    my $newline = $line;    # Make a copy

    while ($line =~ / Name=(.*?) \s+ Password=(.*?) (?:\s+|$) /gx)
    {
        my $name     = $1;
        my $password = $2;
        print "Enter the plain text password for $name, ",
              "password is currently '$password'\n";

        chomp(my $newpass = <>);
        print "You will now swap $password for Password='$newpass'\n";
        print "Continue? (y/n)\n";
        chomp(my $answer  = <>);

        # Change the copy

        $newline =~ s{Password=\Q$password\E}{Password=$newpass}
            if $answer =~ /y/i;
    }

    $line = $newline;       # Update this line in the file
}

untie @array
    or die "Cannot untie file '$filename': $!";

Note that it’s necessary to make the progressive password substitutions to a copy of $line, because changing $line within the while loop resets the /g match position, resulting in an infinite loop. See, e.g., “Global matching” in Using regular expressions in Perl.

Hope that helps,
