XML, SQL, ASP.NET Books to recommend?

Hi,

I’d like to know of any goods books to buy about:
– XML programming/development: I have a very basic knowledge of it right now but would like to take it to a much higher level.

– SQL programming: The only SQL query language I’ve used is with MS-Access, and very basic queries at that. I’d like to know more about MS-SQL Server development or advanced SQL programming development.

– ASP.NET: This is new to me, I’d like to learn to program with it.

All feedback will be greatly appreciated!

Thanks!
