Re: Structured XML Generation using SQL

[Charles Wilt <charles.wilt@xxxxxxxxx>]

Doug,

Are you talking about the whitepaper, "Replacing DB2 Extenders with DB2
Built in Support for XML"?

While I'm not replacing DB2 Extenders...it does appear quite useful.

The step by step buildup is exactly what I was hoping for.

I also ran across these articles

Thank you!
Charles
