C#中初学XML，有点晕，有没有什么方法可以通用的操作xml,读写查询替换等。而不管xml的格式是什么样(有命名空间或没有的)?
在操作xml还有什么readxml和loadxml方式，有些节点有值，有些节点空白，搞了几天还是不清楚。
希望有人做个汇总，对xml的操作，对于任意格式的xml都可以进行读写，任意节点查询等。
不知道行不行？菜鸟期待中.................

xmlDoc.load(filePath);
XmlNode root = xmlDoc.DocumentElement;string xpath = "xpath查询条件";
//查询多个节点
XmlNodeList xnList = root.SelectNodes(xpath);
//查询单个节点
XmlNOde node = root.SelectSingleNode(xpath);===============================================
我是这么用的，从来不管名称空间。Doc对象的载入可以多种方式，路径，文件流，ReadXml对象等等。
