>From the HTML::TokeParser docs:
$p = HTML::TokeParser->new( $filename );
$p = HTML::TokeParser->new( $filehandle );
$p = HTML::TokeParser->new( \$document );
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 undef and $! will tell you why it failed.
If the argument is a reference to a plain scalar, then this scalar is
taken to be the literal document to parse. The value of this scalar should
not be changed before all tokens have been extracted.
Note the the last form.
