Remove specific node from xml

Question

Here is my xml

 <result>
  <client></client>
  <message></message>
  <record>
     <message></message>
   </record>
</result>

I want to remove the "message" node which is right below "result" when I tried to remove it by using below code:

 responseXml.Descendants().Where(e => e.Name == "client" || e.Name == "message").Remove();

It is removing "message" which is under "record" but I don't want this. I want to remove only "message" under "result"

Expected xml:

 <result>
  <client></client>
  <record>
     <message></message>
   </record>
</result>

Please suggest me here.

Descendants() will return all elements (children and grand-children etc.), while Elements() will only return immediate children.

responseXml.Root.Elements().Where(e => e.Name == "message").Remove();

You could probably use the shorter .Element("message") syntax, but be aware that this method only returns the first element found. If you have more than one <message> it wont return/remove them all.

void Main()
{
    string xml =@"
 <result>
  <client></client>
  <message></message>
  <record>
     <message></message>
   </record>
</result>";

XElement root = XElement.Parse(xml);    
root.Element("message").Remove();    
}

Removes exact element "message" directly under root node.

You can call Element(name), which returns a single XElement (calling Elements or Descendants returns a IEnumerable<XElement>):

responseXml.Root.Element("message").Remove();
