Check if node has child records

Is there a way to check to see if a node has child nodes? I've got an xml file that I'm working with that looks something like the xml below. I need to know if the inner menu nodes have children. <menu>                 <item>                                 <menu><menu>                 <item>                 <item>                                 <menu>                 <item><item>                 <item><item>                                 <menu>                 <item> </menu> DUANE BOUDREAU  |  SANDY BAY NETWORKS PRESIDENT AND CHIEF TECHNOLOGY OFFICER P: 902.232.2345 x222   |  P: 603.879.0249 x222   |  F: 866.631.6272 SMART PEOPLE.
