Export VB/C sharp comments to XML

Apologies in advance for these naive multi-tiered questions…

I need to know (like yesterday):
(1) Is there an easy way to programmatically extract comments from VB or C# code into XML files?
(2) How do I construct Word 2003/2007 from XML files?
(3) Can I use XMLSpy to extract VB/C# comments to XML files? How can this be done programmatically within Visual Studio?
(4) Can I use XMLSpy to create Word 2003/2007 files (API docs) from XML files? Can you recommend tools that are less expensive and easier to use for this purpose?
