Question

Hi i am having problems reading out the nodes of a XML file? I cant find the child nodes in the XML. This code finds no nodes. if i change:

XmlNodeList dataNodes = xmlDoc.SelectNodes("//Properties");

To

XmlNodeList dataNodes = xmlDoc.SelectNodes("//NewDataSet");

Then i get two nodes returned i get properties and requestdata, but i want the properties child nodes.

Could some one please tel me why i cant see the child nodes of properties and please help me to find them.

Here is my C# code.

if (File.Exists("C://Users//Shaun//Documents//Visual Studio 2010//Projects//LightStoneTestService//LightStoneTestService//FileTest//Testdo.xml")) //In bin and Debug
    {
    XmlDocument xmlDoc = new XmlDocument();

    xmlDoc.Load("C://Users//Shaun//Documents//Visual Studio 2010//Projects//LightStoneTestService//LightStoneTestService//FileTest//Testdo.xml");

    XmlNodeList dataNodes = xmlDoc.SelectNodes("//Properties");

    foreach (XmlNode node in dataNodes)
      {
        int Count = 0;
        int Max = node.ChildNodes.Count;
        foreach (XmlNode childNode in node.ChildNodes) //For each child node in FieldData
         {
           if (ArrayProperties[Count].LightStoneTag == childNode.Name)
          {
            ArrayProperties[Count].Value = node.SelectSingleNode(ArrayProperties[Count].LightStoneTag).InnerText;
          }
           Count = Count + 1;
         }
      }

New Part

I am having troubles pulling out the inner text, my code is in the foreach above, my app keeps breaking on the line:

ArrayProperties[Count].Value = node.SelectSingleNode(ArrayProperties[Count].LightStoneTag).InnerText;

Could someone please show me how to pull out a value from an XML File.

Answer 1

Here is the sample code

code for loading the file

private const string XML_FILE_NAME = "sample.xml";
public static XmlDocument LoadSampleXML()
    {
        XmlDocument oXmlDocument = null;
        try
        {

            oXmlDocument= new XmlDocument();
            oXmlDocument.Load(XML_FILE_NAME);
            return oXmlDocument;
        }
        catch (Exception ex)
        {
            return oXmlDocument;
        }
    }

Following code you can use to get child nodes

 private const string XML_NODE_PROP = "Properties";
 XmlDocument oXmlDocument = null;
 oXmlDocument = LoadSampleXML();
 XmlNodeList oXMlNodeList = oXmlDocument.GetElementsByTagName(XML_NODE_PROP);

 foreach (XmlNode oXmlNodeItem in oXMlNodeList)
            {
               // DoSomething
            }
