trouble,, need help!

numberuno has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks, I have been following Perl since 1 month, looks interesting. Now, I have a trouble some requirement. 1. read all .log files in a folder (output of Jmeter execution which are basically XML with .log extention) 2. Search for keywords like 2.a. httpSample's attribute value by key lb 2.b. content of failure, error and errormessage tags 3. Print them as report to HTML so that I can send as email Here is the code I have:

 #!/usr/lib/perl
use strict;
use warnings;
use Carp;
use File::Find;
use XML::Parser;
use File::Spec::Functions qw( canonpath );

my $failureMessage = "";
my $failure = "";
my $error = "";
my $value = "";
my $element = "";

#chomp $element;

if ( @ARGV == 0 ) {
    push @ARGV, "C:\\Users\\bijoymeethal\\Desktop\\xml test";
    warn "Using default path $ARGV[0]\n  Usage: $0  path ...\n";
}

open(HTML_FILE, ">BAT_Report.html") ||     die "Can't open file: $!\n"
+;
# Print the initial HTML tags
print HTML_FILE "<html>\n<body>\n<h1>BAT Report - JMeter Test</h1>\n<h
+r><br><table class=MsoTableGrid border=1 cellspacing=0 cellpadding=0 
+><tr><th><p>TestPlan</p></th><th><p>Test Failed?</p></th><th><p>Failu
+reMessage</p></th><th><p>Link to Source</p></th></tr>";
find(
    sub {
        return unless ( /[.]log\z/i and -f );
        extract_information();
        return;
    },
    @ARGV
);

sub extract_information {
my( $expat, $element, %attrs ) = @_;    
#my $line = $expat->current_line;
if ($element eq "httpSample") {
    if( %attrs ) {
        while( my( $key, $value ) = each( %attrs )) {
            if ($key eq "lb"){
            print "\t$key => $value\n";
            }
        }
    }
}elsif ($element eq "failure"){
$failure = $element;
}elsif ($element eq "error"){
$error = $element;
}elsif ($element eq "failureMessage"){
$failureMessage = $element;
}

print HTML_FILE <<"EOF";
<tr><td><p>$value</p><td><p>$failure</p></td><td><p>$failureMessage</p
+></td></tr>
EOF
return;
}
print HTML_FILE "</body><br></html>";
close (HTML_FILE);
