[Rssview-developers] Informa & Parsing

[Christoph W. <sai...@ya...>]

Hi,

I noticed that Informa (our RSS parser) loads DTDs for each feed. In =
plain
english that means that Informa loads RSS 0.91 DTD for each subscribed =
RSS
0.91 feed! This is an unnecessarily waste of system resources. The =
problem
with the Informa Parser classes is that the whole parser subsystem is
realized with static methods that makes extending difficult to =
impossible. I
got no reaction from Informa team for my email :(

In the moment I see two approaches:
* Use Informa and manipulate source
	+ Already works with Rss Viewer
	- Merge changes to Informa into our adapted source

* Switch to a pure RSS Parser Project
	+ Less (unnecessary) code (Informa library comprises classes for
storage etc.)
	+ Better performance (No DTD resoles) and (possibly) better
architecture
	- Some work for adaption
	- Testing with some feeds once more

I've already looked at some pure Parser projects:

Apache Commons FeedParser (in sandbox)
http://jakarta.apache.org/commons/sandbox/feedparser/index.html

Sandler
http://sourceforge.net/projects/sandler

Rome
http://wiki.java.net/bin/view/Javawsxml/Rome

RssLib4J
http://sourceforge.net/projects/rsslib4j/

RssLib J
http://enigmastation.com/rsslibj/

My personal favorit is Rome because of features and api documentation =
and
feed parser because of the apache commons reputation.

I'm awaiting your feedback.

Cheers
Christoph Walcher
