Re: Re: Re: RobotUA not working

Second Reply - Following Update

I'm detecting either a misunderstanding or a lack of knowledge regarding the way Perl represents object references. This may help:

my $q = CGI->new;
print $q;
# outputs
CGI=HASH(0xhhhhhhh)

my $fh = IO::File->new;
print $fh;
# outputs
IO::File=GLOB(0xhhhhhhh)

# Format is:
# <module-name>=<blessed-reference-type>(0x<hex-memory-location>)

Most HTML::Parser methods return an HTML::Parser object. This is what you are outputting. You'll need to supply code in order for me to supply more information :-)

I haven't used this module previously so I wrote a test script to see what's going on. I've posted it after the 'Read more ...', hopefully you'll find something useful there.

The HTML::Parser documentation includes about half-a-dozen example (working) scripts.

Here's my test script:

!#/usr/bin/perl -w

use strict;

use HTML::Parser ();

my $html = q(
<html>
    <head>
        <title>The Title</title>
    </head>
    <body>
        <h1>Heading 1</h1>
        <p>First paragraph.</p>
        <p><em>Second fully emphasized paragraph.</em></p>
        <p>Third <em>partially paragraph.</em></p>
        <p>Para with <strong>BOLD</strong> middle bit.</p>
        <p>Para with <tt>CODE - changed to TT for PM</tt> middle bit.<
+/p>
        <ul>
            <li>dot point 1</li>
            <li>dot point 2</li>
            <li>dot point 3</li>
        </ul>
    </body>
</html>
);

my $ra_want_tags = [ qw(title h1 p em li strong) ];

my %parser_init = (
    api_version => 3,
    text_h      => [\&print_element, 'self'],
    report_tags => $ra_want_tags,
);

my $p = HTML::Parser->new(%parser_init);

do { $p->parse($html) } until ($p->eof);

sub print_element
{
    my $p = shift;
    $p->handler(start =>
        sub {print map {s/^<(.+?)>$/$1: /; $_} @_}, 'text');
    $p->handler(text =>
        sub {print map {s/^\s*(.*?)\s*$/$1\n/; $_} grep /\S/, @_}, 'dt
+ext');
}

Thanks PN5 before i read this i did find some code similar to yours, now it works, thanks for replying though, I did post another Parser question in Seekers of Perl wisdom regarding word combining. Thanks	[reply]
