Cancer Research / Clinical Trials Examples

I am new to XML (but thoroughly steeped in HTML/CSS) and I don't have 
a research or biology background.

I am looking for XML examples related to cancer research and/or 
clinical trials.

I will be presenting them as examples in a (very) short XML 
introduction for researchers. I'd like to have something they can 
relate to. (I did find some citation XML at Pubmed.)

A research paper example would be excellent. Raw XML is fine, a 
transformation with the raw xml would be great.

In the trials area, I'm aware of CDISC and seen some of their 
examples but I'd like to find something that's not in the 
pharmaceutical industry arena and more related to pure research.

I am new to XML (but thoroughly steeped in HTML/CSS) and I don't have 
a research or biology background so be gentle.

Thanks.
