</SystemConfig>我现在想读取这个xml,读game节点，game_name="beijing"的！这个表达式如何写呢？谢谢！

Answer 1

game[/SystemConfig/game/@game_name="beijing"]

Answer 2

哦！我的意思是。读取game_name="beijing"，的game_zhouqitime值

Answer 3

           XmlTextReader reader = new XmlTextReader(sXmlFileName);
            ArrayList alTemp = new ArrayList();
            while (reader.Read())
            {
                if (reader.NodeType == XmlNodeType.Element && reader.Name == "game")
                {
                    while (reader.Read())
                    {
                        if (reader.NodeType == XmlNodeType.Element)
                        {
                             if (reader.Name == "beijing")
                            {
                                String[] sTemp = new String[3];//读取节点
                                     int tempindex = 0;
                                for (tempindex = 0; tempindex <3;tempindex++ )
                                {
                                    sTemp[tempindex] = reader.GetAttribute(tempindex);
                                }
                                alTemp.Add(sTemp);                                //没有读你的game_time节点。
                                     //自己加一下。
                            }
                            else
                                break;
                        }
                    }
                    break;
                }
            }
            reader.Close();            return alTemp;
你的XML中<game那一行最后的一个time有没有问题？感觉好像格式有问题。
上面的代码是从我的项目中摘录出来的，针对你的XML格式未做测试，仅供参考。

Answer 4

1楼正解,3楼,你的是DOM, 不是xpath

Answer 5

game/@game_zhouqitime[/SystemConfig/game/@game_name="beijing"]

Answer 6

//game/@game_zhouqitime[@game_name='beijing']

Answer 7

http://www.w3school.com.cn/xpath/xpath_syntax.asp

Answer 8

doc.SelectSingleNode("//game[@game_name='beijing']").Attributes["game_zhouqitime"];

Answer 9

算了，写完整吧：
              XPathDocument doc = new XPathDocument("c:\\1.xml");
            XPathNavigator nav = doc.CreateNavigator();
            XPathNodeIterator iter = nav.Select("/SystemConfig/game/@game_zhouqitime[/SystemConfig/game/@game_name=\"beijing\"]");
            while (iter.MoveNext())
            {
                MessageBox.Show(iter.Current.Name + ":" + iter.Current.Value);
            }
