i tried this code.But gives an stack overflow error.
XmlDocument doc = new XmlDocument();
doc.Load(path);
XmlNodeList nodes = doc.SelectNodes("//Setting[@name='File1']");
for (int i = nodes.Count - 1; i >= 0; i--)
{
    nodes[i].ParentNode.RemoveChild(nodes[i]);
}
doc.Save(path);

Haha, nodes[i].ParentNode.RemoveChild(nodes[i]); looks like trying "Seppuku" :P

Not exactly sure what are you trying to achieve... you could just call doc.RemoveAll() to remove all but root node (and attributes as well). If you need to delete everything, why not just delete/overwrite a file by path?

Here is what to do:

  • Use all your code shown in your question, then…
  • Call: doc = new XmlDocument();


Easy enough, isn't it? :-)

I didn't get it.

OK. When you delete all nodes, the data of XMLDocument carries no useful information, so, just create a new one. Isn't it logical?

But OP isn't deleting all the nodes, only child nodes of a particular nodes.

I don't think so. Maybe the question is formulated incorrectly, but look -- it says ***all*** XML nodes. How else should I understand it? Don't look at sample code -- this is not an answer.
