Indenting an XML String?

Hey guys, I'm pretty new at using XML objects, but I've got an ASP server using Microsoft.XMLDOM to create an XML object and send the XML string inside a page to the client.
The problem I'm having is that instead of sending a nicely formatted and indented string, it outputs as one line. I've searched for this for a few days now and I can't for the life of me figure out how to pretty-print it. I've seen ways to write to a file (i think) but not a way to just get the string with tabs and newline characters. Anyone know how to do this?

Thanks for any help
