仅定义一个结构并在Go中处理XML文件的所有内部元素？

Suppose I have the following xml:

<main symbol="X">
<blockA main_score="3">
    <a score="0"/>
</blockA>
<blockB>
    <b id="3" name="Mike"/>
</blockB>
</main>

And I'd like to define the following struct (blank tags are parts I want to solve):

type Result struct {
    XMLName xml.Name `xml:"main"`
    Symbol string `xml:"symbol,attr"`
    MainScore int
    Score int
    Id int
    Name string
}

And what I'd like to get is the following struct:

symbol: X
main_score: 3
score: 0
id: 3
name: Mike

So how can I define XML tags that goes into inner elements (blockA, blockB) and also reaches its attribute values (main_score) and inner elements (score, id, name)?

I can address the issue here by defining yet another structs and embedding them within the parent Result struct. However, is it still feasible to NOT use the embedding struct and just define struct tags within the main struct and have it process the whole elements?

Thanks.

I don't think it is currently possible to unmarshal that XML into your structure with the current version of the package.

If it was supported, you'd want to annotate MainScore with:

MainScore int `xml:"blockA>main_score,attr"`

i.e. pick the main_score attribute from the blockA sub-element. This does not currently work though, as described in issue 3688.

At the moment, I think you will need to create nested structs to fully unmarshal the data you're after.
