c#,.net操作XML系列之二(修改节点数据)

接上一篇文章，如果要修改某个节点呢？这个小东西，居然耗费我了一个下午时间找资料(我比较弱智)，琢磨，整理出一段代码如下 

static void UpdateXml()
        {
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(@"D:\Downloads\books\Books.Xml");
            XmlNodeList nodelist = xmlDoc.SelectSingleNode("bookstore").ChildNodes;
            foreach (XmlNode xn in nodelist)
            {
                XmlElement xe = (XmlElement)xn;
                if (xe.GetAttribute("genre") == "轻舞肥羊")
                {
                    xe.SetAttribute("genre", "轻舞肥狗");
                    break;
                }
            }

            XmlNodeList xnd = xmlDoc.SelectNodes("bookstore/book/author/first-name");
            if (xnd != null)
            {
                foreach (XmlNode xddd in xnd)
                {
                    XmlElement xxe = (XmlElement)xddd;
                    if (xxe.InnerText == "lzs")
                    {
                        xxe.InnerText = "随心而遇";
                        break;
                    }
                 
                }
            }
            xmlDoc.Save(@"D:\Downloads\books\Books.Xml");
          
        }

这里面后来的用到XPATH,参考了这篇文章，谢谢原作者. http://www.cnblogs.com/ocean2000/archive/2006/08/08/471029.html
