Deserializing XML file

Question

Hi All,
I am facing issues while deserializing an XML in C#. I am currently using .Net framework 4.6.1.
I am having an XML file which contains a few details which i need to use in my C# WPF application. I am currently facing some issues with regard to this:

I currently have one XML file which i am able to deserialize by mapping all the fields in the XML file to specific classes in the application.

But the problem is that this XML file is not static, it is dynamic. As a result i am not able to map any additional fields in the XML file using the classes that i already have in the application. Hence the deserialization fails in case any additional fields are present in the XML file.

I dont need all the fields in the XML file, i only need about 5 values from the XML file.

Is there any way that this can be made generic so that it will be able to handle the dynamic XML file with the existing classes?

Any help will be appreciated.
Thank you!!

@S Abijith , you could design a dynamic class to adapt your dynamic xml file.

First, you could create the following class to inherit from the class DynamicObject.

using System.Dynamic;  
using System.Linq;  
using System.Xml.Linq;  
  
 class Program  
{  
    static void Main(string[] args)  
    {  
  
        string xml2 = File.ReadAllText("Issue.txt");  
        dynamic zabbix_export = DynamicXml.Parse(xml2);  
        var namelist = zabbix_export.hosts.host;  
        foreach (var item in namelist)  
        {  
            Console.WriteLine(item.name);          //Get Device Name  
        }  
        foreach (var host in namelist)  
        {  
            foreach (var inter in host.interfaces.@interface)  
            {  
                Console.WriteLine(inter.ip);    //Get ip  
            }  
        }  
  
        foreach (var host in namelist)                        
        {  
            var tags = host.tags.tag;  
            if (tags.ToString().Contains("DynamicXml"))  
            {  
                if(tags.tag.ToString()== "Model_Name")  
                {  
                    Console.WriteLine(tags.tag + "**" + tags.value);      //Get tag called Model_Name and its value  
                }  
                    
                           
            }  
            else  
            {  
                var newtag = host.tags.tag;  
                foreach (var item in newtag)  
                {  
                    if(item.tag.ToString() == "Model_Name")  
                    {  
                        Console.WriteLine(item.tag+"**"+item.value);  
                    }  
                }  
                  
            }  
  
  
             
        }  
        
        Console.ReadKey();  
  
    }  
}  
public class DynamicXml : DynamicObject  
{  
    XElement _root;  
    private DynamicXml(XElement root)  
    {  
        _root = root;  
    }  
  
    public static DynamicXml Parse(string xmlString)  
    {  
        return new DynamicXml(XDocument.Parse(xmlString).Root);  
    }  
  
    public static DynamicXml Load(string filename)  
    {  
        return new DynamicXml(XDocument.Load(filename).Root);  
    }  
  
    public override bool TryGetMember(GetMemberBinder binder, out object result)  
    {  
        result = null;  
  
        var att = _root.Attribute(binder.Name);  
        if (att != null)  
        {  
            result = att.Value;  
            return true;  
        }  
  
        var nodes = _root.Elements(binder.Name);  
        if (nodes.Count() >1)  
        {  
            result = nodes.Select(n => n.HasElements ? (object)new DynamicXml(n) : n.Value).ToList();  
            return true;  
        }  
       
  
        XElement node = _root.Element(binder.Name);  
        if (node != null)  
        {  
            result = node.HasElements || node.HasAttributes ? (object)new DynamicXml(node) : node.Value;  
            return true;  
        }  
  
        return true;  
    }  
}  

I write the comment for the specific value and you can have a look.

Updated code:

 foreach (var host in namelist)  
            {  
                foreach (var inter in host.interfaces.@interface)  
                {  
                    Console.WriteLine(inter.ip);    //Get ip  
                }  
            }  

The result is
