From the HTML::TokeParser documentation:
$p = HTML::TokeParser->new( $file_or_doc );
The object constructor argument is either a file name, a file handle
object, or the complete document to be parsed.
If the argument is a plain scalar, then it is taken as the name of a file
to be opened and parsed. If the file can't be opened for reading, then the
constructor will return an undefined value and $! will tell you why it failed.
You didn't pass a file or document to the constructor, you passed a
URL. And you didn't check $! to see why it failed.
