How to parse a URL's content into a Drupal node
Yes, it is possible using hook_node_insert or hook_node_presave. You will just need to implement it like:

function hook_node_insert($node) {
  if ($node-&gt;type == 'CONTENT_TYPE_MACHINE_NAME') {
    // get the URL content here
  }
}


You can do it using the hook_node_presave too. The only difference is that it is called before even the node is saved into the database.
