如何得到xml中最后一个<info>标签中的<id>和<timestamp>的属性值?
如下xml所示：如何得到xml中最后一个<info>标签中的<timestamp>的属性值，即timestamp=1312173361?
- XML code
- <root>- <data> <hasnext>1</hasnext> - <info> <id>118560075872631</id> <timestamp>1330022743</timestamp> </info>- <info> <id>10775055490488</id> <timestamp>1329439413</timestamp> </info>- <info> <id>102585001626915</id> <timestamp>1323588512</timestamp> </info>- <info> <id>85617084111117</id> <timestamp>1323396725</timestamp> </info>- <info> <id>90616081992310</id> <timestamp>1323317410</timestamp> </info>- <info> <id>52621020669019</id> <timestamp>1323133289</timestamp> </info>- <info> <id>9699010815682</id> <timestamp>1321321209</timestamp> </info>- <info> <id>40664105746709</id> <timestamp>1320896842</timestamp> </info>- <info> <id>79594093104019</id> <timestamp>1320896776</timestamp> </info>- <info> <id>55101034977487</id> <timestamp>1320896218</timestamp> </info>- <info> <id>68098006069005</id> <timestamp>1320895842</timestamp> </info>- <info> <id>54101033311228</id> <timestamp>1320894821</timestamp> </info>- <info> <id>38668097211444</id> <timestamp>1320887989</timestamp> </info>- <info> <id>89594043056973</id> <timestamp>1320836219</timestamp> </info>- <info> <id>35199130299086</id> <timestamp>1320745725</timestamp> </info>- <info> <id>26160037617200</id> <timestamp>1315538589</timestamp> </info>- <info> <id>89552116897653</id> <timestamp>1315387425</timestamp> </info>- <info> <id>95523052545030</id> <timestamp>1312947079</timestamp> </info>- <info> <id>11636067646985</id> <timestamp>1312788015</timestamp> </info>- <info> <id>22141054836576</id> <timestamp>1312685215</timestamp> </info>- <info> <id>25607081109756</id> <timestamp>1312423867</timestamp> </info>- <info> <id>44049088666798</id> <timestamp>1312358464</timestamp> </info>- <info> <id>73535113056798</id> <timestamp>1312257547</timestamp> </info>- <info> <id>93018133245703</id> <timestamp>1312173361</timestamp> </info> <timestamp>1334285419</timestamp> <totalnum>24</totalnum> </data> <errcode>0</errcode> <msg>ok</msg> <ret>0</ret> </root>
[解决办法]
Linq的XDocument的LastNode ，看帮助
或者用XmlDocument的SelectNodes 找到一组，然后访问最后有一个索引的Node
[解决办法]
看看xpath
XmlDocument x = new XmlDocument();
x.Load(@"c:\test.xml");
XmlNodeList xnl = x.SelectNodes("//data/info[last()]/timestamp");
foreach (XmlNode xn in xnl)
{
Console.WriteLine(xn.InnerText);
}
