How to handle XML with same descendant names?

I have an unfortunate issue where the names of the root element and descendant element are the same, the second one has more descendents with info. Example below:

<dispatchnames>
    <dispatchnames>
        <first>mike</first>
        <last>allison</last>
    </dispatchnames>
    <dispatchnames> 
        <first>jeff</first>
        <last>ellington</last>
    </dispatchnames>
</dispatchnames>

I am attempting to code in C#, this is my current code for XML without the same name:

XDocument xdoc = XDocument.Parse(xmlString);
IEnumerable<TrackData> data = from info in xdoc.Descendants("dispatchnames")
                              select new TrackData(
                                  info.Element("first").Value,
                                  info.Element("last").Value);

How should I handle it?

Add a where clause to verify that that element isn't the root element. If that element isn't actually the root, check info.Element("first") != null instead

XDocument xdoc = XDocument.Parse(xmlString);
IEnumerable<TrackData> data = from info in xdoc.Descendants("dispatchnames")
                              where xdoc.Root != info
                              select new TrackData(
                                          info.Element("first").Value,
                                          info.Element("last").Value);

Also, note that the XML you posted isn't well-formed. I tested this with XML structured as follows:

<dispatchnames>
    <dispatchnames>
        <first>mike</first>
        <last>allison</last>
    </dispatchnames>
    <dispatchnames> 
        <first>jeff</first>
        <last>ellington</last>
    </dispatchnames>
</dispatchnames>
