This is definitely out of scope in an ASP group. You're talking about
doing something on a client machine. ASP is strictly server-side
technology.
"click a button"? Where do you imagine this button being located?
You will likely need to use a client application that hooks into the
browser process to get at the DOM. I don't think this is trivial,
especially if you need to make it browser-independent. But anyways, you
should ask in a group that focusses on whatever application language
(VB, C++, etc.) you wish to use to accomplish this.

Why not just do File->Save As...
