//从百度获取到的地图相关的XML内容
string xmlData = string.Empty;
XmlDocument doc = new XmlDocument();
//doc.Load(@"D:\csharp\output\output\loc.xml");
doc.LoadXml(xmlData);
XmlNode node = doc.SelectSingleNode("GeocoderSearchResponse/result/cityCode");
if (node != null)
{
Console.WriteLine(node.InnerText);
}
Console.ReadLine(); Console.ReadLine();
