Yes. The kind of stream doesn't matter, actually, it will pull data from the
stream until it's read a complete document.

It wouldn't actually read all of the file into memory, it would read it
piecewise and construct an in-memory representation of the XML document it
represents while it's doing so. This will end up quite a bit larger than 1
GB, actually. This is why XmlDocument is unsuitable for very large streams.
XmlReader and XPathNavigator are light-weight alternatives.
