Deserialize XML with multiple elements into single C# object

I need to deserialize an XML document that looks like:

<Root>
  <Items>
    <Item>
      <ItemHeader Attr1="A" Attr2="B" Attr3="C" />
      <ItemDetails Attr4="D" Attr5="E" />
    </Item>
    ...
  </Items>
</Root>

Into a class that looks like: [Serializable, XmlRoot("Item")] Public class MyItem { [XmlAttribute("Attr1")] public string Attr1 { get; set; } [XmlAttribute("Attr5")] public string Attr5 { get; set; } }

An I am using the following code to perform the deserialization: XDocument doc; XElement rootElem = doc.Element("Root");

foreach (XElement xe in rootElem.Descendants("Item"))
{
  MyItem item = new MyItem();
  XmlSerializer xmlSerializer = new XmlSerializer(typeof(MyItem));
  XmlReader xRdr = xe.CreateReader();
  item = (MyItem)xmlSerializer.Deserialize(xRdr);

}

However, none of the elements are copied into the object instance.

Is this doable? Do I need to deserialize each sub Element?

Thanks
