Retrieve NODES within bounding box with XAPI

Hello,
I’ve been reading the xapi wiki here http://wiki.openstreetmap.org/wiki/Xapi.

I’m trying to construct a URL that returns ALL nodes within a bounding box WITHOUT the ways and relations. I can’t find an example URL on the xapi site. I’ve tried constructing my own, but I’m starting to think the API doesn’t handle this type of use case.

Here’s my best shot at constructing a URL:
http://xapi.openstreetmap.org/api/0.6/node[*][bbox=-121.6572,47.4223,-121.603,47.4691]” [/*]

Ideas?

Thanks
