Remarks
The following XML contains an attribute in a specific namespace:
<test xmlns:dt="urn:datatypes" dt:type="int"/>
You can lookup the dt:type attribute using one argument (prefix and local name) or two arguments (local name and namespace URI):
String dt = reader.GetAttribute("dt:type");
String dt2 = reader.GetAttribute("type","urn:datatypes");
To lookup the xmlns:dt attribute, use one of the following arguments:
String dt3 = reader.GetAttribute("xmlns:dt");
String dt4 = reader.GetAttribute("dt",http://www.w3.org/2000/xmlns/);
You can also get this information using the Prefix property.
