/*读xml*/
private static void ReadXml(string result)
{
XmlDocument documents = new XmlDocument();
documents.LoadXml(result);//加载xml数据
XmlNode xn = documents.SelectSingleNode("root");//获取到root节点
//XmlNode root = doc.DocumentElement;//这也可以获取到根节点
XmlNodeList xnls = xn.ChildNodes;//获取到root节点下的所有子节点
//string statusText = documents.GetElementInnerText("status");//获取到status节点文本值
for (int i = 0; i < xnls.Count; i++)//遍历root节点下的所有字节点
{
string zx_typeType = xnls[i].GetAttributeValue("zx_type");//获取到root字节点zx_type属性值
xnls[i].Attributes["zx_type"].Value //获取到root字节点zx_type属性值
string text = xnls[i].InnerText;//获取到root子节点文本值
}
}
