使用c#读取XML内部子节点

Reading XML inner child node using c#

我正在尝试在 c# 中读取 xml。我能够读取节点 \\'ArrayOfCruisePriceSummaryResponse\\' 但我如何读取内部节点。

XmlNodeList xmlnode;

xmlnode = xml.GetElementsByTagName("CruisePriceSummaryResponse");



for (int i = 0; i <= xmlnode.Count - 1; i++)

{



}

xmlnodes = xml.GetElementsByTagName("CruisePriceSummaryResponse");



for (int i = 0; i < xmlnodes.Count; i++)

{

  XmlNodeList rooms = xmlnodes[i].SelectNodes("RoomSize/CruisePriceSummaryRoomSize");

  for(int j = 0; j < rooms.Count; j++)

    string bestFare = rooms[j].SelectSingleNode("BestFare/TotalPrice").InnerText;

    string fullFare = rooms[j].SelectSingleNode("FullFare/TotalPrice").InnerText;

}

使用 GetElementsByTagName 我可以到达该节点，但我如何读取内部孩子。我想从 BestFare 和 FullFare 中读取 TotalPrice 每个孩子有两个内在孩子 BestFare 和 FullFare，我需要读取每个 TotalPrice .

XmlNodeList xmlnode;

xmlnode = xml.GetElementsByTagName("CruisePriceSummaryResponse");



for (int i = 0; i <= xmlnode.Count - 1; i++)

{

  }

}

P.S 我不想使用 LINQ，因为我正在使用 VS2008 处理 SSIS 项目，它不支持 LINQ。

您可以使用各种 SelectNode 变体来遍历文档并提取数据。

试试这个：

XmlNodeList xmlnode;

xmlnode = xml.GetElementsByTagName("CruisePriceSummaryResponse");



for (int i = 0; i <= xmlnode.Count - 1; i++)

{
