Convert XmlElement to XElement with Elements("ElementName") Returns No Results

Question

I'm using the following code to convert a XmlElement to XElement

public staic XElement ToXElement(this XmlNode node) {
    XElement element = null;
    if (null != node) {
        element = XElement.Parse(node.OuterXml);
    }
    return element;
}

However when I call Elements() or Elements("ElementName") I get no results.
I do however get results from calling Nodes().

Why don't the elements come up from calling Elements and what's the difference between the two methods?

Here is a snippit of the xml I'm parsing.

<Feature xmlns="http://schemas.microsoft.com/sharepoint/">
    <ElementManifests>
        <ElementFile Location="Path/file.xml"/>
    </ElementManifests>
</Feature>

You are probably not using the namespace correctly. Both of these methods work correctly for me:

XElement root = XElement.Load("test.xml"); //or result of ToXElement
foreach(var item in root.Elements())
{
    Console.WriteLine(item.Name);
}

XNamespace ns = "http://schemas.microsoft.com/sharepoint/";
var manifestsNode = root.Element(ns + "ElementManifests");

Given that you don't know the difference between the Elements() (get all direct children) and Element() (get one specific direct child element) you should start with a Linq to Xml tutorial.
