Building a graph out of OSM XML

I'm a complete beginner in OSM. My final year project involves using OSM to create routing algorithms.

I've been playing with Osmosis to parse OSM XML data and I think I can work with it.

My question is if I need to build a graph out of OSM XML data, what would I need to parse?

I know I need the ways, but I'm not sure if I need to also parse the nodes and relations?

Keep in mind, this is a simple routing app for walking/running/cycling

Any helpful suggestions would be deeply appreciated!
