indexing list of words in a file
Hey all,

I'm doing a project currently and want to index words in a webpage.
So there would be a file with webpage content and a file with list of words, I want an output file with true and false that would show which word exists in the webpage.

example:

Webpage content data.html


Code:

You can try something like this:
Code:
awk '
NR==FNR{a[$1]; next}
{for(i in a)a[i]+=gsub(i,x)}
END{for(i in a){print i,a[i]==0?"false":"true"}}
' words.dat data.html

I read the problem as determine if a word from the list exists in the content of the webpage:
Code:
#! /usr/bin/perl

use strict;
use warnings;
use LWP::Simple;

$\ = "\n";

my $url  = shift(@ARGV);

unless (defined $url && '' lt $url) {
    print STDERR $0, ': missing url';
    exit(1);
}

my $content = get($url);

unless (defined $content) {
    print STDERR $url, ': has no content';
    exit(1);
}

while (<>) {
    chomp;
    print index($content, $_) < 0 ? 'false' : 'true';
}

which would be invoked as:
Code:
perl hindex http://www.online.net/serveur-dedie/offre-dedibox-qc.xhtml wordlist

which results in:
Code:
true
true
false
false
false
true
false

Now this returns 'true' or 'false' depending on the existence of a sequence of characters in the content of the webpage, not splitting out words, removing html tags, and the like. You would need something like HTML::Parser to do that:
Code:
#! /usr/bin/perl

use strict;
use warnings;

use LWP::Simple;
use HTML::Parser;

$\ = "\n";

my %WORDS = ();

sub text {
    my $text = shift(@_);
    return unless defined $text;
    foreach my $w (split ' ', $text) { $WORDS{lc $w}++; }
}

my $url = shift(@ARGV);

unless (defined $url && '' lt $url) {
    print STDERR 'USAGE: ', $0, ' <url> [<wordlist>]';
    exit(1);
}

my $content = get($url);

unless (defined $content) {
    print STDERR $url, ': has no content';
    exit(1);
}

HTML::Parser->new(text_h => [ \&text, 'text' ])->parse($content);

while (<>) {
    chomp;
    print defined $WORDS{$_} ? 'true' : 'false';
}

Which, when invoked, returns:
Code:
true
false
false
false
false
false
false

Please note that this example does not skip over the contents of <script> tags and the like.
