如何封送XML

Question

I have two structs in order to marshal into XML

//Accounts ...
type Accounts struct {
    XMLName     xml.Name `xml:"account"`
    AccNumber   string   `xml:"iban"`

}

//Accounts ...
type AccountsList struct {
    XMLName    xml.Name   `xml:"response"`
    ResultCode string     `xml:"resultCode"`
    Accounts   []Accounts `xml:"result"`
}

I'm getting next xml structure:

<response>
    <resultCode>...</resultCode>
    <account>
        <iban>...</iban>
    </account>
    <account>
        <iban>...</iban>
    </account>
</response>

But I need also <result> tag, so I need next xml:

<response>
    <resultCode>...</resultCode>
    <result>
        <account>
            <iban>...</iban>
        </account>
        <account>
            <iban>...</iban>
        </account>
    <result>  
</response>

Why Golang XML marshaller is ignoring this thing xml:"result" in AccountsList structure? Is it possible to get result I want without using third structure?

Answer 1

You can change the field tag name from result to result>account:

type AccountsList struct {
    XMLName    xml.Name   `xml:"response"`
    ResultCode string     `xml:"resultCode"`
    Accounts   []Accounts `xml:"result>account"`
}

This will wrap your accounts slice with result tag.
