self training and MCP Exam 70-310

I'm relitively new to XML. I'd like to try learning it on my own. Lately, I've done little more than read about it in an MS core reference and online documents. I'd also like to have some application of the technology, but I'm having trouble finding any practice problems. Does anyone know of a website or resource that provides practice problems or something like it? I want to apply what I learn so I can better remember it to give me a better foundation.

Eventually, I'll begin studying for the MS MCP 70-310 Exam. Does anyone have any hints on a good way to preparing for the exam? I've heard the 70-310 is easy, but I'm not going to underestimate it especially after seeing the course descriptions for it.
