Obtaining XmlElement from XDocument

Question

I have to pass a whole XML document into a 3rd party function. The parameter is XmlElement.

To do this until now, I've successfully been using this:

XmlDocument doc;
//doc = ...
XmlElement root = doc.DocumentElement;
3rdPartyFunction(root);

But now I'm using XDocument instead of XmlDocument:

XDocument doc;
//doc = ...
//how to call 3rdPartyFunction?

How do I call the function in this case? Can I convert from "Xml" to "X"?

Why don't you just read it in as an `XmlElement` in the first place? — Jeff Mercado, Jul 27 '13 at 21:58
@JeffMercado I don't control the 3rd party function and can't change it. — roger.james, Jul 27 '13 at 22:01

You misunderstood my question, but my question misunderstood your question. :) I missed the first part of your question. — Jeff Mercado, Jul 27 '13 at 22:07

Use this:

var newDoc = new XmlDocument();
newDoc.LoadXml(doc.ToString());
3rdPartyFunction(newDoc);

What happens if the xml file has 250K lines? :) – Mechanical Object Jul 27 '13 at 22:08
You are right, it's better to use doc.CreateReader() and newDoc.Load() – Adrian Trifan Jul 27 '13 at 22:13
The parameter type is `XmlElement`; you cannot just pass `XmlDocument`. – mousio Jul 30 '13 at 07:43

[Updated]

XmlDocument xmldoc = new XmlDocument();
using (XmlReader reader = xdoc.CreateReader())
{
    xmldoc.Load(reader);
}
XmlElement root = xmldoc.DocumentElement;
3rdPartyFunction(root);
