QueryPath is a PHP library for manipulating XML and HTML. It is designed to work not only with local files, but also with web services and database resources. It implements much of the jQuery interface, but it is heavily tuned for server-side use.
In this demo, QueryPath uses OpenAmplify and four other web services to take a starting article and collect related content from around the web. SVG, autotagging, Flickr, Twitter, Technorati, and Amazon integration are all discussed in this 8 minute screencast.
