How to Select XML Node by name in C#

Introduction

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

For this, the purpose of code is to "How To Select XML Node by name in C#". We use MVC(C#) for creating this demo.

We use XPath Expression for selecting the XML node.

What is XPath?

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

Using the Code

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

<info>
  <collage>
    <name>SIGMA INSTITUTE</name>
    <students>650</students>
  </collage>
  <collage>
    <name>ORCHID INSTITUTE</name>
    <students>1200</students>
  </collage>
</info>

We want to get all <collage> nodes. So, our XPath Expression is "/info/collage".

Create the Below ActionResult Method

        public ActionResult Index()
        {
            try
            {
                //Create A XML Document Of Response String
                XmlDocument xmlDocument = new XmlDocument();

                //Read the XML File
                xmlDocument.Load("D:\\demo.xml");

                //Create a XML Node List with XPath Expression
                XmlNodeList xmlNodeList = xmlDocument.SelectNodes("/info/collage");

                List<Info> infos = new List<Info>();

                foreach (XmlNode xmlNode in xmlNodeList)
                {
                    Info info = new Info();
                    info.CollageName = xmlNode["name"].InnerText;
                    info.Students = xmlNode["students"].InnerText;

                    infos.Add(info);
                }

                return View(infos);
            }
            catch
            {
                throw;
            }
        }

Create the Below Class & Declare Properties

        public class Info
        {
            public string CollageName { get; set; }

            public string Students { get; set; }
        }

Create a View

@model IEnumerable<SelectXMLNode.Controllers.HomeController.Info>

@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
    <div>
        @if (Model.Count() > 0)
        {
            foreach (var item in Model)
            {
                <div class="row">
                    <div class="col-md-6">Collage: @item.CollageName </div>
                    <div class="col-md-6">Number Of Students: @item.Students</div>
                </div>
            }
        }
    </div>
</body>
</html>
