I have made a script that fetches the title of a (supposed) web page. The problem arises when I give a big file (which is n't even text/html) to the script. The file gets downloaded (waste of bandwidth) and after downloading it, the script notices it isn't text/html. Here's the script:
#!/usr/bin/perl -w
use HTML::TokeParser;
use LWP::Simple;
use Encode;
sub getTitle {
my $stream = HTML::TokeParser->new(@_);
if(defined $stream->get_tag("title")) {
my $title = $stream->get_trimmed_text;
return encode_utf8($title);
}
}
my $browser;
my $url = $ARGV[0];
BEGIN {
use LWP::UserAgent;
$browser = LWP::UserAgent->new;
$browser->agent("Mozilla/5.0");
$browser->timeout(15);
}
my $resp = $browser->get($url);
die "Error getting $url: ", $resp->status_line, "\n"
unless $resp->is_success;
die "Not HTML, it's ", $resp->content_type, "\n"
unless $resp->content_type eq 'text/html';
if(my $title = getTitle($resp->content_ref)) {
print "Title: '$title'\n";
}
What would be the solution for this? I should probably make a limit of some sort, say 32kB, for the get(). This seems to be a common problem, but I haven't found a decent solution.
Also, should I worry about the content-encodings of the pages or does encode_utf8() take care of those too?
Thanks in advance.
