NAME
    HTML::PullParser - Alternative HTML::Parser interface

SYNOPSIS
     use HTML::PullParser;

     $p = HTML::PullParser->new(file => "index.html",
                                start => 'event, tagname, @attr',
                                end   => 'event, tagname',
                                ignore_elements => [qw(script style)],
                               ) || die "Can't open: $!";
     while (my $token = $p->get_token) {
         #...do something with $token
     }

DESCRIPTION
    The HTML::PullParser is an alternative interface to the HTML::Parser
    class. It basically turns the HTML::Parser inside out. You associate a
    file (or any IO::Handle object or string) with the parser at
    construction time and then repeatedly call $parser->get_token to obtain
    the tags and text found in the parsed document.

    The following methods are provided:

    $p = HTML::PullParser->new( file => $file, %options )
    $p = HTML::PullParser->new( doc => \$doc, %options )
        A "HTML::PullParser" can be made to parse from either a file or a
        literal document based on whether the "file" or "doc" option is
        passed to the parser's constructor.

        The "file" passed in can either be a file name or a file handle
        object. If a file name is passed, and it can't be opened for
        reading, then the constructor will return an undefined value and $!
        will tell you why it failed. Otherwise the argument is taken to be
        some object that the "HTML::PullParser" can read() from when it
        needs more data. The stream will be read() until EOF, but not
        closed.

        A "doc" can be passed plain or as a reference to a scalar. If a
        reference is passed then the value of this scalar should not be
        changed before all tokens have been extracted.

        Next the information to be returned for the different token types
        must be set up. This is done by simply associating an argspec (as
        defined in HTML::Parser) with the events you have an interest in.
        For instance, if you want "start" tokens to be reported as the
        string 'S' followed by the tagname and the attributes you might pass
        an "start"-option like this:

           $p = HTML::PullParser->new(
                  doc   => $document_to_parse,
                  start => '"S", tagname, @attr',
                  end   => '"E", tagname',
                );

        At last other "HTML::Parser" options, like "ignore_tags", and
        "unbroken_text", can be passed in. Note that you should not use the
        *event*_h options to set up parser handlers. That would confuse the
        inner logic of "HTML::PullParser".

    $token = $p->get_token
        This method will return the next *token* found in the HTML document,
        or "undef" at the end of the document. The token is returned as an
        array reference. The content of this array match the argspec set up
        during "HTML::PullParser" construction.

    $p->unget_token( @tokens )
        If you find out you have read too many tokens you can push them
        back, so that they are returned again the next time $p->get_token is
        called.

EXAMPLES
    The 'eg/hform' script shows how we might parse the form section of
    HTML::Documents using HTML::PullParser.
