zip files

Is it possible to handle zip files using some variation of the xpath document() function in .NET 2.0?
Because xml compresses so very well, uncompressing it means that it can take a lot of disk space. So, I'd like to be able to process it without unzipping it into a file.

:eek: Umm... most browsers can't even read zip files (and don't try to).

Firefox might be able to help, using the jar: protocol. But that's about it.
