向一个xml文档中插入另一段xml文档的问题

我想向一段xml文档中插入另一段xml文档，使用如下语句：



XmlDocument xIn = new XmlDocument();

xIn.LoadXml(XMLin);

XmlNode newlog = xIn.SelectSingleNode("//log");        

XmlDocument log = new XmlDocument();

log.Load(@"D:\data\log.xml");

XmlNode addNode = log.ImportNode(newlog, true);

(log.GetElementsByTagName("logs"))[0].AppendChild(addNode);

log.Save(@"D:\data\log2.xml");

插入后发现新插入的节点带有命名空间，这个应该怎样去掉？
另外，有没有更好的插入方法？ --------------------编程问答-------------------- 你先后面那段把节点的头都去掉用XMLread 在插入看看. --------------------编程问答-------------------- 学习学习~ --------------------编程问答-------------------- 把你XML拿出来我帮你看. --------------------编程问答-------------------- to herty：
我不会用XMLread插入，有没有相关代码？ --------------------编程问答-------------------- xIn：
