in reply to Extract HTML Table rows

The modules recommended by suaveant and bobf are a good bet. If you wanted to use HTML::TreeBuilder the following would be one way to do it.
#! /usr/bin/perl use strict; use warnings; use Data::Dumper; $Data::Dumper::Indent=1; use HTML::TreeBuilder; my $t = HTML::TreeBuilder->new_from_file(*DATA); my ($table) = $t->look_down(_tag => q{table}); my @rows = $table->look_down(_tag => q{tr}); my %db; for my $row (@rows){ my $key = $row->look_down(class => q{rlab})->as_text; my $value = $row->look_down(class => q{l})->as_text; $db{$key} = $value; } for my $key (keys %db){ printf qq{%s -> %s\n}, $key, $db{$key}; } __DATA__ <html><head><title>Person Profile</title></head> <center> <font size=5><b>Profile</b></font> <table cellspacing="1" cellpadding="1"> <tr> <td class="rlab">Short Name:</td> <td class="l">John</td> </tr> <tr> <td class="rlab">Long Name:</td> <td class="l">John Abraham</td> </tr> <tr> <td class="rlab">Company:</td> <td class="l">Idea</a></td> </tr> </tr> <tr> <td class="rlab">Currency:</td> <td class="l">EUR</td> </tr> </table> </body></html>
Company: -> Idea Long Name: -> John Abraham Currency: -> EUR Short Name: -> John
I've assumed that
  • there is one table,
  • each row has two columns each with a class as in your sample data
You would probably want to include some error checking to confirm those assumptions though.
