Maybe extensions for LinqToXML

Example.cs

public class Person
{
    public string Name { get; set; }
    public List<string> Numbers { get; set; }

    public static Person FromXml(XElement xml)
    {
        return new Person
                   {
                       Name = xml.Element("Name").MaybeValue(),
                       Numbers = xml.Element("Numbers").MaybeElements("Number").Select(e => e.MaybeValue()).ToList()
                   };
    }
}

XElementExtensions.cs

public static class XElementExtensions
{
    public static XElement MaybeElement(this XElement element, XName name)
    {
        if (element == null) return null;
        return element.Element(name);
    }

    public static IEnumerable<XElement> MaybeElements(this XElement element)
    {
        if (element == null) return Enumerable.Empty<XElement>();
        return element.Elements();
    }

    public static IEnumerable<XElement> MaybeElements(this XElement element, XName name)
    {
        if (element == null) return Enumerable.Empty<XElement>();
        return element.Elements(name);
    }

    public static string MaybeValue(this XElement element)
    {
        return element == null ? null : element.Value;
    }

    public static string MaybeValue(this XAttribute attribute)
    {
        return attribute == null ? null : attribute.Value;
    }
}
