How to get child nodes of an element in an XML in a WPF application? 

 

While parsing an XML in a WPF application, I fell in a need to fetch the child nodes of an element. I put the question on stackoverflow and got many responses but at last I was able to answer that question myself.

 

Lets consider the problem:

 

Suppose I have following XML

 

 
   
      hello
      john
      hi
      marry
   
   
      00
     
      00
     
   
  
  

 

Now I have to get the values of Node1, Node2, Node3, Node4 ie, hello, john, hi, marry in a list whose parent element is Segment with Name as "AAA". So first of all I will try to reach at segment with name attribute as "AAA" and then I will check whether that elements has child nodes or not. If that segment element contains child nodes, then I will fetch the innertext of all the child nodes.

 

Below is the C# code for fetching the child nodes of an element

 

public static void GetChildElements()
{
    List lstChildElements = new List();
   XmlDocument xmlDocument = new XmlDocument();
   xmlDocument.Load(XMLFileLocation);

   XmlNodeList xnList = xmlDocument.SelectNodes("/Loop/Loop/Segment[@Name='AAA']");
   foreach (XmlNode xn in xnList)
   {
     if (xn.HasChildNodes)
     {
       foreach (XmlNode childNode in xn.ChildNodes)
       {
          lstISAElements.Add(childNode.InnerText.ToString());
       }
     }
   }
   foreach (string childElement in lstChildElements)
   {
     Console.WriteLine(childElement);
   }     

}
