How to remove a XMLNode from XMLDocument occuring at multiple nested levels

Question

I have a XML which has a node which kind of gets repeated across multiple levels in the file using C#.

Example of the XML:

The easiest way is to use XDocument instead of XmlDocument. Use .Descendants() to find all Nodes of a specific name/type. Then .Remove() them.

string xml = @"
     
         
         Test Name
         1239859895
     
     
         
         
             29893893893
             test1
             test
         
             
 ";

XDocument xdoc = XDocument.Parse(xml);
xdoc.Descendants("isbn").Remove();
string result = xdoc.ToString();

But if you want to go with XmlDocument use this code:

 XmlDocument xmldoc = new XmlDocument();
 xmldoc.LoadXml(xml);
 foreach (var node in new  List(xmldoc.GetElementsByTagName("isbn")
                                         .OfType()).Where(
                                         x => x.ParentNode != null))
 {
     node.ParentNode.RemoveChild(node);                      
 }

 string result = xmldoc.OuterXml;
