Perl in a Nutshell, 2nd Edition

Name

parse_file

Synopsis

$p->parse_file(file)

Reads HTML into the parser object from the given file, which can be a filename or an open filehandle.

When the parse or parse_file method is called, it parses the incoming HTML with a few internal methods. In HTML::Parser, these methods are defined, but empty. Additional HTML parsing classes (included in the HTML modules or ones you write yourself) override these methods for their own purposes. For example:

package HTML::MyParser;
require HTML::Parser;
@ISA=qw(HTML::MyParser);

sub start {
     your subroutine defined here
     }

The following list shows the internal methods contained in HTML::Parser.
