Answer 1

You can write an extension for linq.

public static XmlNode GetXmlNode(this XElement element)
{
    using (XmlReader xmlReader = element.CreateReader())
    {
        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.Load(xmlReader);
        return xmlDoc;
    }
}

Since you have your XElement,you can convert it.(blog post)

element.GetXmlNode();

Hope this helps

Answer 2

The following method will convert any XNode into an XmlNode

XmlDocument doc = new XmlDocument(); //cached as a member variable for performance.
//recreating it inside ToXmlNode works fine too.

XmlNode ToXmlNode(XNode xnode) {
    using(var reader = myElem.CreateReader())
        return doc.ReadNode(reader);
}

That means it'll support entire documents, individual elements, text nodes, comments, processing instructions - most things except XAttribute.

However, this is something you should avoid. Try to stick with either the new System.Xml.Linq API, not to mix it with the XmlDocument-based API. This new API is easier to work with, and in any case, mixing API's like this is makes for harder-to-maintain code. If you must mix API's, it's probably cleaner to convert the entire document at one rather than copy individual nodes back and forth, particularly if your data-structure is mutable.

However, if you just need some quick interop, the above will work fine and reasonably efficiently.
