Re: text extract

[Roger]

I remember you came here a while ago asking for advise on how to automatically parse online staff info html pages into useful data. How far are you into your project anyway? Did you experiment with the various CPAN modules mentioned in the replies to your original post?

Ok, I have written a demo using the following modules:
LWP::UserAgent ... to fetch the HTML source
HTML::Strip ... to strip HTML tags

use strict;
use warnings;
use LWP::UserAgent;
use HTML::Strip;

# fetch the html source
my $ua = new LWP::UserAgent;
my $req = new HTTP::Request (GET => 'http://www.ntu.edu.sg/eee/eee4/cv
+/eekteoh.htm');
my $res = $ua->request($req);

die "unable to fetch HTML source: $res->status_line"
    if !$res->is_success();

my $html = $res->content();     # fetch the html source
$html =~ s/\x0D//g;             # convert to unix format

# grab the html fragments
my ($research_interest, $selected_publications) = $html =~
   /(Research Interests.*)(Selected Publications.*)Projects/s;

# strip html tags
my $hs = HTML::Strip->new();

$research_interest = $hs->parse( $research_interest );
$research_interest =~ s/\n+/\n/sg;
$research_interest =~ s/(Research Interests)/$1\n------------------/;

$selected_publications = $hs->parse($selected_publications);
$selected_publications =~ s/\n+/\n/sg;
$selected_publications =~ s/(Selected Publications)/$1\n--------------
+-------/;

$hs->eof;

print "$research_interest\n\n$selected_publications";

And the output -

Research Interests
------------------
Computer Vision and Pattern Recognition
Autonomous Navigation of Outdoor AGVs
Intelligent Systems
Robotics
Industrial Automation


Selected Publications
---------------------
