As you indicated that you are working with an XmlDocument, you need to remove a child XmlElement node via the RemoveChild method on the parent node:

    string xml = @"
        
            
                
                Test Name
                1239859895
            
            
                
                
                    29893893893
                    test1
                    test
                
                    
        
        ";
    // Initialize and load the XmlDocument
    var doc = new XmlDocument();
    doc.LoadXml(xml);

    // Delete all XmlElements named "isbn".
    var list = doc.DocumentElement.GetElementsByTagName("isbn").OfType().ToArray();
    foreach (var element in list)
    {
        var parent = element.ParentNode;
        if (parent != null)
            parent.RemoveChild(element);
    }
    var newXml = doc.OuterXml;
    Debug.WriteLine(newXml);

And the output is:

  
    
    Test Name
  
  
    
    
      test1
      test
