How to remove null valued child nodes in Xml using c#

I have an XML Documnet consisting parent nodes and child nodes, 

<?xml version='1.0' encoding='UTF-8'?> 
<response>   
   <system_timestamp>2016-10-21 13:40:28</system_timestamp>
   <response_data>   
    <status>Active</status>   
    <profile>     
     <first_name>John</first_name>
     <last_name>Abraham</last_name>
     <ship_to_address>        
      <address_1>null</address_1>      
      <address_2>null</address_2>  
      <city>null</city>      
      <state>null</state>   
      <postal_code>null</postal_code> 
     </ship_to_address>  
    </profile>
  </response_data>  
</response>

I am having few null valued child nodes like <address_1> and <address_2>. So, now how would I remove those null values of my child nodes. I tried

doc.Descendants().Where(e => string.IsNullOrEmpty(e.Value)).Remove();

But this is not working . And i am using this XmlDocument doc = new XmlDocument(); doc.LoadXml(_value);

code to parse xml document. Do we have any other methods to remove using XMLDocument instead of XElement.

e.Value isn't a null reference or an empty string - it's the string "null" because that's the value in your element.

You want:

doc.Descendants().Where(e => (string) e == "null").Remove();
