Reading XML inner child node using c#

Question

I am trying to read xml in c#. I am able to read the node 'ArrayOfCruisePriceSummaryResponse' but how can i read the inner nodes.

XmlNodeList xmlnode;
xmlnode = xml.GetElementsByTagName("CruisePriceSummaryResponse");

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

}

Using GetElementsByTagName I am able to reach to that node but how can I read the inner child. I want to read TotalPrice from BestFare and FullFare Each child has two innerchilds BestFare and FullFare and I need to read each TotalPrice .

PS I dont not want to use LINQ because I am working on a SSIS project using VS2008 and it does not support LINQ.

You can use the various SelectNode variants to traverse your document and extract your data.

Try this:

XmlNodeList xmlnodes;
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;

        // do whatever you need
    }
}
