Running batch: Read and show Slashdot's RDF-feed

Example #1

Comment:

This code reads the Resource Description Framework (RDF) of Slashdot and presents it in the browser, using a small piece of javascript. A list of all items in the RDF is retreived using the getElementdBytagName method. In a loop, all items are traversed and the properties of each item are put in an associative array for easier access.
