Let’s first establish what the purpose of the code is in the first place.

For this, the purpose of the code is to "How to select XML node by name in C#". We use MVC (C#) to create this demo.

We use XPath expression to select XML node.

What is XPath?

XPath is a path expression to select the nodes or node-sets in an XML document.

Code

Now, we have the XML document given below. Save it as demo.XML.

  1. <info>  
  2.   <collage>  
  3.     <name>SIGMA INSTITUTE</name>  
  4.     <students>650</students>  
  5.   </collage>  
  6.   <collage>  
  7.     <name>ORCHID INSTITUTE</name>  
  8.     <students>1200</students>  
  9.   </collage>  
  10. </info>  
We want to get all <collage> nodes. Thus, our XPath Expression is "/info/collage".

  7.   
  8.         //Read the XML File  
  9.         xmlDocument.Load("D:\\demo.xml");  
  10.   
  11.         //Create a XML Node List with XPath Expression  
  12.         XmlNodeList xmlNodeList = xmlDocument.SelectNodes("/info/collage");  
  13.   
  14.         List<Info> infos = new List<Info>();  
  15.   
  16.         foreach (XmlNode xmlNode in xmlNodeList)  
  17.         {  
  18.             Info info = new Info();  
  19.             info.CollageName = xmlNode["name"].InnerText;
