How to Deserialize XML with Same Attribute Name in 2 Different Element?

Question

My class definition:

[Serializable]
public class MyClass
{
    [XmlAttribute(AttributeName = "ID")] //Problem is here. same attr name ID.
    public int XXX_ID { get; set; }

    [XmlElement(ElementName = "XXX")]
    public string XXX_Value{ get; set; }

    [XmlAttribute(AttributeName = "ID")] //Problem is here. same attr name ID.
    public int YYY_ID { get; set; }

    [XmlElement(ElementName = "YYY")]
    public string YYY_Value { get; set; }
}

My XML:

<MyClass>
    <XXX ID="123">Some Values</XXX> 
    <YYY ID="567">Some Values</YYY>
</MyClass>

My Problem:

I want to de-serialize the above XML into an object.

During the runtime, an error has occurred, it is not allowed to have same attribute name in 2 different elements and under the same root.

How to solve this problem?

P/S: I cannot change the XML, I am not the owner of it.

Thanks in advance.

Note: [Serializable] does nothing useful here

To do that you either need to do the (de)serialization manually, or you need to DTO to have roughly the same layout as the xml. For example:

public class Something { // need a name here to represent what this is!
    [XmlAttribute] public int ID {get;set;}
    [XmlText] public string Value {get;set;}
}

then

public class MyClass {
    public Something XXX {get;set;}
    public Something YYY {get;set;}
}
