Question

I can remove an xml node using

 XmlNode node = newsItem.SelectSingleNode("XYZ");
 node.ParentNode.RemoveChild(node);

But what if I want to remove multiple nodes at once, for example XYZ,ABC,PQR?

Is there any way to remove all of these nodes at once or do I have to remove them one by one?

NOTE: XYZ,ABC,PQR being at the same level(i.e they all have same parent)

Answer 1

Nothing is inbuilt when using the XmlDocument API, but you could write a utility extension method, for example:

public static void Remove(this XmlNode node, string xpath)
{
    var nodes = node.SelectNodes(xpath);
    foreach (XmlNode match in nodes)
    {
        match.ParentNode.RemoveChild(match);
    }
}

then call:

newsItem.Remove("XYZ|ABC|PQR");

If you can change to the XDocument API, then things may be different.
