XDocument Add multiple XElements

In my Windows Phone 8 C#/XAML .NET 4.5 Project, I'm trying to create an XDocument with similar structure:

<element1>
  <subelement1>
  </subelement1>
  <subelement2>
     ...etc...
  </subelement2>
</element1>

<element2>
  <subelement1>
  </subelement1>
  <subelement2>
     ...etc...
  </subelement2>
</element2>

The method creating the document looks like (simplified for the question purposes):

... createXML()
{
    XDocument doc = new XDocument();

    XElement elem1 = new XElement("element1");
    elem1.Add(new XElement("subelement1"));
    XElement elem2 = new XElement("element2");

    doc.Add(elem1);
    doc.Add(elem2);
}

But I keep getting InvalidOperationException saying that it would create a invalid document structure.

I know why - it would cause the document to have multiple "root nodes" - but I effectively need it that way.

This structure is needed for webservice done by third party, which recieves the document as a string.

So the question is "How to achieve this structure? Should I use some other XObject instead?"

(I know that probably the most simple solution would be to use collection of XElements...just askin' if there is another way out of curiosity)

The structure that you specified at the top of the post is illegal, because valid XML documents must have a single root element; your document has two elements at the top level, which is not allowed.

You can solve this problem by adding a root element at creation time, and then discarding it when reading the document;

document = new XDocument(new XElement("root", elem1, elem2));
