zzgulu, I'm very happy to continue helping. Two things, though: 1) This thread has gotten long enough and pushed so far to the right that I'm responding to your original message. 2) It seems your current code is not in sync with your original data example, so it would be helpful to re-post them.

To your last question, how to print one value only if you have another value: You should assemble a record as you process the lines; then undef the record when you get to the end-of-record marker; perhaps printing the record first if it has all the elements.

I mocked up the following, but again, it doesn't work with your data sample. Either the data or the expressions need to change. 

use strict;
use warnings;

my $file = "z.txt";
open my $fh, "<", $file or die "Unable to open $file: $!";
my %record;
while (<$fh>) {
    chomp;
    if (/EOU/){
        if (exists $record{'u_val'} &&
            exists $record{'p_val'} &&
            exists $record{'m_val'} )
        {
           print "$record{'u_val'}\n",
                 "\t$record{'p_val'}",
                 "\t$record{'m_val'}\n";
        }
        %record = ();
    } elsif (s/\bProcessing\s\d+\.tx\.\d+: //) {
        $record{'u_val'} = $_;
    } elsif (s/\bPhrase: //) {
        s/\"//g;
        $record{'p_val'} = $_;
    } elsif (/\s\s/) {
        $record{'m_val'} = $_;
    }
}
close $fh;
