Google search in your site

Access to remote pages tutorial

Google allows at the moment and for learning porpoises to get access to their search engine and to get XML files with search results. In the script bellow this option is used to access that XML file and to extract from it the information we will latter display in our page (the way url, titles and snippet are extracted is a bit irregular).

This service from Google is for personal use and you must open a Google account to be able to use this service. They will provide you a Key you must include in the script . Extracting the same information from a regular google searchresults page is not legal.
