Not an XSL, but it is better than that.Here is a deadlock shredder by Wayne Sheffield.

You can take the xml from the graph that is produced by XE and just pass it as a parameter if you like.
You can also retrieve it directly from the XE session.
This shredder is highly efficient and will shred those nasty multi-victim deadlocks.
Thanks. I will look at when I come back on shift tonight. Right now I need to go get some sleep.
