doubledecker has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I am trying to extract the following text from HTML page using the following code, but my code fails..

Budget - $25,000,00
Gross(worldwide) - $58,500,00

#!/usr/bin/perl use HTML::TokeParser; my $content = <<HTML; <h5>Budget</h5> $25,000,000 (estimated)<br/> <br/> <h5>Opening Weekend</h5> $727,327 (USA) (<a href="/date/09-25/">25 September</a> <a href="/year +/1994/">1994</a>) (33 Screens)<br/> <br/> <h5>Gross</h5> $28,341,469 (USA) (<a href="/date/08-05/">5 August</a> <a href="/year/ +2012/">2012</a>)<br/>&#163;2,344,349 (UK) (<a href="/date/05-18/">18 +May</a> <a href="/year/1995/">1995</a>)<br/>&#163;1,732,123 (UK) (<a +href="/date/04-16/">16 April</a> <a href="/year/1995/">1995</a>)<br/> +$58,500,000 (Worldwide)<br/>$555,480 (Belgium)<br/>ESP 637,291,985 (S +pain)<br/> <br/> <h5>Admissions</h5> 82,890 (Belgium)<br/>163,594 (France) (<a href="/date/03-28/">28 March +</a> <a href="/year/1995/">1995</a>)<br/>410,811 (Germany) (<a href=" +/date/12-31/">31 December</a> <a href="/year/1995/">1995</a>)<br/>1,2 +45,604 (Spain)<br/> <br/> <h5>Filming Dates</h5> <a href="/date/06-16/">16 June</a> <a href="/year/1993/">1993</a>&nbsp +;-&nbsp;<a href="/date/09-10/">10 September</a> <a href="/year/1993/" +>1993</a><br/> <br/> HTML my $description = ""; my $parser = HTML::TokeParser->new(\$content) || die "Can't open: $!"; while (my $token = $tp->get_tag("h5")) { my $text = $parser->get_text(); last if $text =~ /budget/i; }

    you're using interpolating heredocs :) double-quoted here docs :) strict vars or warnings would have warned you
    #!/usr/bin/perl -- use strict; use warnings; use XML::LibXML 1.70; ## for load_html/load_xml/location use Data::Dump qw/ dd /; my %shabs; my $dom = XML::LibXML->new( qw/ recover 2 / )->load_html( string => $c +ontent ); for my $h5 ( $dom->findnodes( q{ //h5 } ) ){ print $h5->nodePath, "\n"; my $key = $h5->textContent; my $next = $h5->nextSibling; while( $next ){ print $next->nodePath, "\n"; $shabs{$key} .= $next->textContent; $next = $next->nextSibling; last if eval { $next->tagName eq 'h5' } ; } print "\n"; } dd( \%shabs );

    In what way does your code fail? Even if it parses the HTML correctly, it will not produce any output as there is not print or anything similar in the code.

    Why choose tokeparser? Where does this $parser variable come from?
      Updated the code to reflect the parser object. Apologies for the same.
        the other question is more important :)
