获取字符串装 的 类容
此字符串格式为
<input cmdcode = “0x0416” deviceid = “?” userid = “?”>
<userid>0</userid>
<pwd>0</pwd>
</input>
如何获取
<userid>
<pwd>
的值
是把字符串转换成XML在进行获取吗？

[解决办法]
用C#读xml

XmlDocument doc = new XmlDocument();
doc.Load("aaa.xml");
XmlNode userIDNode = doc.SelectSingleNode("input").SelectSingleNode("userid");
XmlNode pwdNode = doc.SelectSingleNode("input").SelectSingleNode("pwd");
string userid = userIDNode.InnerText;
string pwd = pwdNode.InnerText;
Console.Write("userid:"+userid+",pwd:"+pwd);
