Sadly some of the older legacy sites are just not available in rss, I had such a scraping request recently. I have to say that with drupal_http_request you don't even have to look at curl. You can do all sorts of things, even faking logins. To parse the HTML use querypath, a trick that we use is to first run some sort of HTML tidyup library on the downloaded page, otherwise querypath runs away crying. beautify module can help you a great deal with that.

Most of the time, you can get to the posts via RSS. Aggregator module does a pretty good job of pulling stuff in, and the author of the post that's displayed is whatever you tell it to display (see Drupal Planet for an example) Thanks, Cameron

I second the recommendation of using QueryPath. I use it almost exclusively along with drupal_http_request, though I use curl only in a few places (if you use curl I recommend http://drupal.org/project/curl for a dependency check). I'd really recommend though creating a custom module that uses the above and then has your logic for filtering in it, I've done this for about a dozen modules now. That said, there are some more modules available out there nowadays, such as using http://drupal.org/project/feeds_xpathparser with feeds http://drupal.org/project/feeds There are about a dozen more modules that will accomplish the goal though I haven't used them, but I went through and tried most of the methods out for some recent projects.

I've finally got round to doing some serious work on Drupalversity, an open, web-based Drupal education project I've had in mind for a year or so.
People who use Drupalversity to learn have the option of adding Resources to the site - i.e., links to posts at Lullabot, Chapter3 etc that explain how to do specific things with Drupal. A Resource is a custom content type that includes a link to the resource and a text field containing a description of that resource.
What I'd like to do once a Resource has been added to the site is to scrape certain information from it: at this point I'm thinking the Title of the page the link points to and the provider of the resource - e.g., which Drupal shop originally created the resource. What's the best way to go about doing this? I'm pretty sure there's not a Drupal module that solves the problem out of the box.
So far I've considered:
- http://drupal.org/project/querypath - Drupal's built-in drupal_http_request() -
http://api.drupal.org/api/drupal/includes--common.inc/function/drupal_http_r... - curl
