Using Linq to pull from IEnumerable and store in data table

Question

I have a datatable that looks like the following

public static DataTable SetColumnHeaders(DataTable KeyDataTable)
{
    KeyDataTable.Columns.Add(\"First_Name

You can bake your "isInsured" check and your selection of a person into the one query;

var query = from p in xmlDoc.Elements()
            where ((string)p.Element("InsuredOrPrincipalInfo")
                        .Element("InsuredOrPrincipalRoleCd")) == "Insured"
            select new
            {
                Firstname = (string)p.Element("GeneralPartyInfo")
                .Element("NameInfo")
                .Element("PersonName")
                .Element("GivenName"),

                LastName = (string)p.Element("GeneralPartyInfo")
                .Element("NameInfo")
                .Element("PersonName")
                .Element("Surname"),
            };

var person = query.FirstOrDefault();
if (person != null)
{
    var fileRow = AutoDataTable.NewRow();
    fileRow["First_Name"] = person.Firstname;
    fileRow["Last_name"] = person.LastName;
}

This isn't super-robust in terms of handling XML in an unexpected format, but it should serve as a good starting point for you. Just fill out the anonymous object initialization with the rest of your elements, casting to the desired types.
