C＃代码：

XmlDocument xdcDocument = new XmlDocument();

xdcDocument.Load(@"E:\\Hotel.xml");

XmlElement xelRoot = xdcDocument.DocumentElement;
XmlNodeList listOfContacts = xdcDocument.SelectNodes("/HotelValuedAvailRS/ServiceHotel/HotelInfo");
foreach (XmlNode xndNode in listOfContacts)
{
    string name = xndNode["Name"].InnerText;
    string order = xndNode["Order"].InnerText;
}

我没有通过上面的代码从上面的XML中获得任何细节。请帮帮我。

Answer 1

您用于选择listOfContacts的xpath与文档中的内容不匹配。更改它以指定您感兴趣的节点的实际路径。

实际上，循环中的元素名称也没有。您期望文档中的哪些节点匹配？

编辑＃1：实际上，现在你已经指定了整个文档，这更有意义。我必须自己编译并运行它，但事实证明你在xpath中缺少一个名称空间声明。您已将根元素声明为名称空间http://www.hotelbeds.com/schemas/2005/06/messages，但您只有xpath选择无名称空间中的元素。

解决此问题的最简单方法是在xpath中的每个元素名称前面使用前缀：

"/ns:HotelValuedAvailRS/ns:ServiceHotel/ns:HotelInfo"

并将定义了此前缀的XmlNamespaceManager传递给SelectNodes。

无法获取XmlDocument.SelectNodes来检索值？
