Get enum values based on attribute

I have an enum. I'm binding values to the combo. But I should get the values based on an attribute as below? How can I do this?

combo1.DataSource = Enum.GetValues(typeof(AnimalType)).Where(Attribute["IsWild"] = true);

public class AnimalEnum : XmlEnumAttribute

    {
        public bool IsWild { set; get; }
    }

    public enum AnilmalType
    {
        [AnimalEnum(Name = "Dog", IsWild = false)]
        Dog,
        [AnimalEnum(Name = "Cat", IsWild = false)]
        Cat,
        [AnimalEnum(Name = "Tiger", IsWild = true)]
        Tiger,
        [AnimalEnum(Name = "Lion", IsWild = true)]
        Lion
    }

Your help is greatly appreciated.
