Answer 1

注意你的xml字符串有两个地方要改下:第一:="?xml version='1.0' encoding='gb2312' ?>   ->> 最前面要加一个"<"第二:第二条记录中itemNode改成ItemNode...

Answer 2

don't forget ..using System.Xml;

Answer 3

不好意思，上面写错了，是下面的.NET Framework 类库  
DataSet.ReadXml 方法

TO:那怎么获得列名呢？
string  strXML="?xml  version='1.0'  encoding='gb2312'  ?><Root>";  
             strXML+="<ItemNode  姓名='胡军'  批号='1'  ></ItemNode>";  
             strXML+="<ItemNode  姓名='张三'  批号='2'  ></itemNode></Root>";  如我要获得，姓名这个列名，我先只能获得值，不能获得列名~~~for example:string strXML = "<?xml version='1.0' encoding='gb2312' ?><Root>";
            strXML += "<ItemNode 姓名='胡军' 批号='1' ></ItemNode>";
            strXML += "<ItemNode 姓名='张三' 批号='2' ></ItemNode></Root>";
            XmlDocument doc = new XmlDocument();
            doc.LoadXml(strXML);
            XmlNodeList nodes = doc.SelectNodes(@"//ItemNode");
            foreach (XmlNode node in nodes)
            {
                foreach (XmlAttribute attribute in node.Attributes)
                {
                    Console.Write(attribute.Name + "=" + attribute.Value + "\t");
                }
                Console.WriteLine();
            }输出:
姓名=胡军 批号=1
姓名=张三 批号=2
