I understand that if the Airport Express is plugged into a router through the ethernet port it can act as a WiFi access point. I also understand that it can act as a client to an existing WiFi access point to allow music streaming and be a print server.

What I'm wondering is if the ethernet port will act as a bridge when the Airport Express is a WiFi client. Specifically, can I plug my XBox into it and have the XBox connect over WiFi to my existing access point/router?
