The Parse Filter and Text Filter stuff currently in Abdera has never quite been fully fleshed out. The Parse Filter is primarily useful as a means of filtering out parse events we don't care about in order to reduce the memory footprint of a parse. The Text Filter was intended to provide a means of parse-time, policy based filtering of feed content. I'm not aware of anyone actually using the Text Filter and it's implementation leaves a lot to be desired performance wise. I'd like to pull the Text Filter stuff back out and simplify the Parse Filter even further, including a simplification of the parser implementation so that filtering is done using a Stax filter rather than if statements in the FOMBuilder. Doing so should result in a more streamlined impl.
