Transform XML Log error during chained builds

[Dave_Novak]

I have logging set to XML so that I can use the handy "Transform XML Log" action at the end of my builds. However, this does not work with chained builds. The problem is that the XML in the log file is not "well-formed" when doing nested builds.

To reproduce, simply add a "Transform XML Log" action to the end of the Chain.bld example.
