C＃代码

XmlDocument xdcDocument = new XmlDocument();

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

var nsmgr = new XmlNamespaceManager(xdcDocument.NameTable);
nsmgr.AddNamespace("ns", "http://www.hotelbeds.com/schemas/2005/06/messages");

var nl = xdcDocument.SelectNodes("/ns:HotelValuedAvailRS/ns:ServiceHotel/ns:HotelInfo", nsmgr);

foreach (XmlNode xndNode in nl)
{
    string name = xndNode["Name"].InnerText;
    var nl3 = xdcDocument.SelectNodes("/ns:HotelValuedAvailRS/ns:ServiceHotel/ns:HotelInfo/ns:ImageList/ns:Image", nsmgr);
    foreach (XmlNode xndNode3 in nl3)
    {
        string url = xndNode3["Url"].InnerText;
        string order = xndNode3["Order"].InnerText;
    }

}

我想阅读每个酒店信息中的图像列表下的每个细节。但我的第二个foreach循环所有图像列表细节，而没有移动到第一个foreach循环的下一个酒店信息。

Answer 1

当你这样做时：

var nl3 = xdcDocument.SelectNodes("/ns:HotelValuedAvailRS/ns:ServiceHotel/ns:HotelInfo/ns:ImageList/ns:Image", nsmgr);

您请求.../ns:Image的所有xdcDocument代码，如果您只想选择每个ns:Image的{{1}}，则必须使用xndNode SelectNodes方法xndNode 1}}：

var nl3 = xndNode.SelectNodes("ns:ImageList/ns:Image", nsmgr);

请注意xPath中的更改，因为现在我们已经处于ns:HotelInfo级别。
