Yeah, I worked on a Rails 1.x app which integrated with an xml feed. IIRC, the options were a library that used regexes internally and had horrible performance (but might have been fine for rss feeds), and another library which wrapped a C library and used callbacks[1]. Definitely was a huge pain point and probably was a mistake for me to use the latest hep environment for that app, but for the rest of Rails it might have been worth it.
