Hi Pravin,

That will work however, while it will use less memory than a hash, it will use a lot more cycles. you are grepping through the (potentially large array) for every line of the file.

Any time you want to quickly check if something is in a list, use a hash...

Regex is not really suited to parsing HTML, you should consider using a Perl module such as XML::Simple.
