如何使用按字母顺序排序的元素将结构编组为XML？

Question

I need to get XML string with ordered elements from structs with unordered fields.

There is main struct:

type Person struct {
    Name string
    Age  int
    OtherData interface{}
}

And there are also a great many other structs, such as:

type SomeStruct1 struct {
    Job   string
    Hobby string
}

type SomeStruct2 struct {
    SkillName  string
    SkillValue int
    *SomeStruct3
}

These structs can have other embedded structs.

I get structs like this:

    sample := &Person{}
    sample.Name = "Vasya"
    sample.Age = 35
    sample.OtherData = SomeStruct1{"programmer", "driving"}

Then I need to get XML with elements ordered by their names:

<Person>
    <Age>35</Age>
    <Name>Vasya</Name>
    <OtherData>
        <Hobby>driving</Hobby>
        <Job>programmer</Job>
    </OtherData>
</Person>
