I've figured out how to do some basic parsing of a CCD using T-SQL and thought I would share the result.
If anyone knows a better way to do this, please feel free to comment. I'm particularly interested in reducing the text associated with the namespace declaration.
I know I could simply remove the namespace (xmlns="urn:hl7-org:v3") from the original xml, however, I would prefer not to do that.

You can use WITH XMLNAMESPACES.

You can also make it a bit shorter by using cross apply.
