刚刚开始我的第一次参加XPathNavigator.
这是我的简单xml: <?xml version="1.0" encoding="utf-8" standalone="yes"?> <theroot> <thisnode> <thiselement visible="true" dosomething="false"/> <another closed node /> </thisnode> </theroot> 现在,我使用CommonLibrary.NET库来帮助我一点: public static XmlDocument theXML = XmlUtils.LoadXMLFromFile(PathToXMLFile); const string thexpath = "/theroot/thisnode"; public static void test() { XPathNavigator xpn = theXML.CreateNavigator(); xpn.Select(thexpath); string thisstring = xpn.GetAttribute("visible",""); System.Windows.Forms.MessageBox.Show(thisstring); } 问题是它无法找到属性.我已经查看了MSDN上的文档,但是无法理解正在发生的事情. 解决方法
这里有两个问题:
(1)您的路径是选择thisnode元素,但thiselement元素是具有属性和的元素 试试这个: public static XmlDocument theXML = XmlUtils.LoadXMLFromFile(PathToXMLFile); const string thexpath = "/theroot/thisnode/thiselement"; public static void test() { XPathNavigator xpn = theXML.CreateNavigator(); XPathNavigator thisEl = xpn.SelectSingleNode(thexpath); string thisstring = xpn.GetAttribute("visible",""); System.Windows.Forms.MessageBox.Show(thisstring); } (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
