Thanks dbc the first method works perfectly for what i need to do, :) i really appreciate your help, i created this class:

public static partial class XmlEnumExtensions
{
    public static Nullable FromReflectedXmlValue(this string xml) where TEnum : struct, IConvertible, IFormattable
    {
        try
        {
            var obj = (from field in typeof(TEnum).GetFields(BindingFlags.Public | BindingFlags.Static)
                       from attr in field.GetCustomAttributes()
                       where attr != null && attr.Name == xml
                       select field.GetValue(null)).SingleOrDefault();
            if (obj != null)
                return (TEnum)obj;
             // OK, maybe there is no XmlEnumAttribute override so match on the name.
            return (TEnum)Enum.Parse(typeof(TEnum), xml, false);

        }
        catch (ArgumentException ex)
        {
            throw new ApplicationException("Error: " + ex.Message);
        }
    }
}

And then I just call the method FromReflectedXmlValue like this:

var obj4 = XmlEnumExtensions.FromReflectedXmlValue("theXmlAtributeValue");
