是否可以像代码中那样对单个标签使用多个标签值

Question

type XMLStruct struct {
    Name    string  `json:"name" json:"FirstName"`
    Date    string  `xml:"Date" xml:"pudDate"`
}

I am going to say no not in this way.

you can do this,

type XMLStruct struct {
    Name    string  `json:"name" xml:"name"`
    Date    string  `json:"Date" xml:"Date"`
}

or this,

type XMLStruct struct {
    Name        string  `json:"name, omitempty" xml:"name, omitempty"`
    Date        string  `json:"Date, omitempty" xml:"Date, omitempty"`
    FirstName   string  `json:"FirstName, omitempty" xml:"FirstName, omitempty"`
}

But I don't believe that you can map multiple json names to one struct field and I think that the reason for this would be is what if they both existed in the json structure, which one do you retain and throw away etc.
