英文:
Golang: Parse both XML element value and attributes for groups
问题
我有一个像这样的XML结构：
<RootLevel status="new" timestamp="1383259529" xmlns="http://someplace.com">
<Item active="1" status="new" itemid="451254">
<SubItem active="1" recent="false" usertext="No idea" id="78421">
<SubItemField active="1" ready="no" type="1">1.4</SubItemField>
<SubItemField active="1" ready="yes" type="2">4.5</SubItemField>
</SubItem>
</Item>
</RootLevel>
我不知道如何获取SubItemField元素的值和属性，我的代码大致如下：
type RootLevel struct {
XMLName xml.Name `xml:"RootLevel"`
...
Item []Item
}
type Item struct {
...
SubItem []SubItem
}
type SubItem struct {
...
SubItemField []SubItemField
}
type SubItemField struct {
Active bool `xml:"active,attr"`
Ready string `xml:"ready,attr"`
}
我需要获取属性和值，但我所知道的唯一方法就是使用
SubItemField []float32
而不是我的自定义类型。顺便说一下，我正在使用xml.Unmarshal。
有什么想法吗？
谢谢。

I have an XML structure like this:
<RootLevel status="new" timestamp="1383259529" xmlns="http://someplace.com">
<Item active="1" status="new" itemid="451254">
<SubItem active="1" recent="false" usertext="No idea" id="78421">
<SubItemField active="1" ready="no" type="1">1.4</SubItemField>
<SubItemField active="1" ready="yes" type="2">4.5</SubItemField>
</SubItem>
</Item>
</RootLevel>
I don't know how I can gather both values and attributes for the SubItemField elements, my code is something like:
type RootLEvel struct {
XMLName xml.Name `xml:"RootLevel"`
...
Item []Item
}
type Item struct {
...
SubItem []SubItem
}
type SubItem struct {
...
SubItemField []SubItemField
}
type SubItemField struct {
Active bool `xml:"active,attr"`
Ready string `xml:"ready,attr"`
}
I need both attributes and values but the only way to get values that I know is just use
SubItemField []float32
instead of my custom type. I am using xml.Unmarshal btw.
Any idea?
Thanks.

我自己弄清楚了如何做到这一点，我只需要在我的结构体中添加一个与xml:",chardata"匹配的新属性，就像这样：
type SubItemField struct {
Value float32 `xml:",chardata"`
Active bool `xml:"active,attr"`
Ready string `xml:"ready,attr"`
}
希望这对某人有所帮助，因为没有关于这个的文档或示例。
英文:
I figured myself how to do that, I had simply to add a new property in my struct that match xml:",chardata" so it looks like:
type SubItemField struct {
Value float32 `xml:",chardata"`
Active bool `xml:"active,attr"`
Ready string `xml:"ready,attr"`
}
I hope that can help someone cos there is no documentation or examples about this.
