上面是要操作的XML，下面是我自己的代码。
XmlDocument xml = new XmlDocument();
xml.Load("loss.xml");
XmlNodeList xnl = xml.SelectNodes("/PathList/Path/DataList/Data");
foreach (XmlNode x in xnl)
{
string firstName = x["Frequency"].InnerText;
string lastName = x["Value"].InnerText;
Console.WriteLine("{0}\t {1}", firstName, lastName);
}
问题是我不想一次遍历出所有结果，我想按 <PathName>PM_CableLoss</PathName>这个字段分别遍历，知道有好的方法，但一直想不出，对Linq to xml也不熟，求大神相助，谢谢！
