In Yahoo! pipes you can build your TSS feed reader with no code, all what you should do is just:
1. Drag and drop the Fetch Site Feed block, and then write “http://www.theserverside.com”.
2. Drag a filter block and define in the rules:
item.title -> contains -> “Java”.
3. Link the blocks together, as described in the screenshot below.
