You can do this by transforming to another source tree, but you will
need to make sure your stylesheet produces a well-formed XML document.
It will also require a fair amount of memory, since you'll have multiple
trees in memory at the same time.
Is there any reason you just can't transform to a memory buffer? Take a
look at the StreamTransform sample for more information on how to do
that. This requires more parsing time, but doesn't place any limitations
on the result of the transformation, and doesn't require multiple trees
in memory at the same time.
