If your perl is not very old, replace the -w (in the shebang) by the
lexical

use warnings ;


use MyTest;

my $test = MyTest->new();

Variant:

my $test = new MyTest ;


$test->load("test.html");
print "numTags = " . $test->numTags() . "\n";


Variant:

$test->load('test.html') ;
print "numTags = @{[ $test->numTags() ]}\n" ;

or even:

print "numTags = $test->{numTags}\n" ;

(which bypasses the method)
