Read in an XML file that has a namespace defined

Hi Experts,

I have the below XML file which I cannot change!

Select all Open in new window

How can I read in and/or set the value of Motorola.Config.CommConfig.IPAddr?  I tried this but it doesn't seem to work:

                   XmlDocument document = new XmlDocument();
                    document.Load(path);
                    XmlElement xmlRoot = document.DocumentElement;

                    XmlNode node = xmlRoot.SelectSingleNode("/Config/CommConfig");

Select all Open in new window

node comes back as null! Eventhough, I can see that Motorola has a child node called Config

Thanks
