XPathDocument 读取带命名空间的节点

StreamReader responseStream = File.OpenText(@"file.xml"); XPathNavigator resNav = (new XPathDocument(responseStream)).CreateNavigator();// 解析带命名空间的节点XmlNamespaceManager manager = new XmlNamespaceManager(resNav.NameTable); manager.AddNamespace("ns", "http://www.wc3.com");string value = resNav.SelectSingleNode("/ns:name", manager).Value;

大致的格式是“命名空间前缀：节点名称”
