Populate a database with domain names from an rdf file


I use a script, provided by za-k/ (adrpo) to populate a database with URLs from an rdf file.

Here is the RDF file:

It populates my database with over 400,000 URLs and many are sub-pages of the same domain.

Now I only want domain names in my database.


     should be included as is but

         should be placed into the database as


because I only want the domain names and not the full URL.

Thanks for the help!

Do you have a smaller version of the RDF file?

I took a quick look at the other script.  At first, I don't see a need to have the sleep.  That just slows it down.  It should be fine running without the sleep.

You could use this:


$_ =  $SavedLink;
    if ( /^((http[s]?|ftp):\/)?\/?([^:\/\s]+)((\/\w+)*\/)([\w\-\.]+[^#?\s]+)(.*)?(#[\w\-]+)?$
/ ) 
        # do the insert here
        $domainLinkOnly = "$2://$3";
        insert into url values('$domainLinkOnly');
