hi, i am new to perl and i have a problem. i saw ur code and thought if u could help me out. i have to write a code to extract links from a webpage and store them in a mysql database.I have the script to extract the links and also i have stored them in the database but not as i want it to be stored. i did like to have each url in the "links" column to be stored in different rows. what i get is all values extracted from a given url are getting stored in one cell and are seperated by commas. I want them to be inserted into different rows. the follwoing is the code
use LWP::UserAgent; use HTML::LinkExtor; use URI::URL; $url =<> ;; # for instance $ua = LWP::UserAgent->new; # Set up a callback that collect image l +inks my @a = (); #@imgs = (); whereever i find img i change to a for hype +rlinks. sub callback { my($tag, %attr) = @_; return if $tag ne 'a'; push(@a,values %attr);#push(@imgs, values %attr); } # Make the parser. Unfortunately, we don't know the base yet (it + might be diffent from $url) $p = HTML::LinkExtor->new(\&callback); # Request document and parse + it as it arrives $res = $ua->request(HTTP::Request->new(GET => $url), sub {$p->parse($_[0])}); # Expand all image URLs to absolut +e ones my $base = $res->base; @a = map { $_ = url($_, $base)->abs; } @a; # Print them out print join("\n", @a), "\n"; use strict; use DBI(); my $dbh = DBI->connect("DBI:mysql:database=.....;host=mysql.serv...... +","xxxxxx","xxxxxx"); #$dbh->do("CREATE TABLE htmllinks (webpage VARCHAR(80) not null primar +y key ,links VARCHAR(80) null)"); $dbh->do("INSERT INTO htmllinks VALUES ('$base',' @a')");
