XML ДОБАВЛЕНИЕ НОВЫЙ ЭЛЕМЕНТ ВНУТРИ EXISTING XML

Question

Вот код, который я пытался добавить узел в существующий XML,

XmlDocument doc = new XmlDocument(); 
XmlNode root = doc.DocumentElement; 
XmlElement elem = doc.CreateElement("price"); 
doc.LoadXml("<Hotel><OptionNo>1</OptionNo><StayDateRange Start=\"15/04/2012\" End=\"17/04/2012\"/><Property Id=\"31461\" CityCode=\"666\" CityName=\"MUMBAI\" CountryCode=\"246\" CountryName=\"INDIA\" StateCode=\"7332\" StateName=\"Maharashtra\" StarRating=\"1\" Chain=\"\" Status=\"Available\" HotelName=\"Airlines International Hotel\" Preferred=\"Yes\" BuiltYear=\"\" RenovationYear=\"\" NoOfFloors=\"\" Location=\"YOGA INSTITUTE RD,PRABHAT COLONY,SANTACRUZ(E),MUMB Mumbai\" MinimumRate=\"4733.43\" Currency=\"INR\"><Address><Address1>YOGA INSTITUTE RD,PRABHAT COLONY,SANTACRUZ(E),MUMB Mumbai</Address1><Address2/><CityCode>666</CityCode><CountryCode>246</CountryCode><PostalCode>400055</PostalCode><CityName>MUMBAI</CityName></Address><Description Name=\"Comprising of 27 rooms in total, this small budget hotel is clean and comfortable, making it the ideal choice for both business and leisure travellers.

root = doc.DocumentElement; 
elem = doc.CreateElement("OtherHotelImage"); 
elem.InnerText = "URL"; 
root.AppendChild(elem); 
doc.Save(Console.Out); 

Я пытался добавить новый узел в указанном XML, который находится внутри <OtherHotelImages> элемента. но он создается внутри корневого элемента, который равен <Hotel>. Пожалуйста, предложите, это срочно.

Answer 1

Вы вызываете root.AppendChild() ... так что да, он входит в корень. Вам нужно пройти дерево XML до тех пор, пока не найдете нужный элемент - и , затем добавьте новый элемент в , который.
