我试图解组下面的代码,底部有go操场 . data.DocumentType总是返回0并且应该返回内部xml 4.有人可以告诉我为什么这不起作用?

package main

import (
    "encoding/xml"
    "fmt"

)

type doc struct {
    XMLName       xml.Name `xml:"ownershipDocument"`
    SchemaVersion string   `xml:",innerxml"`
    DocumentType  int      `xml:",innerxml"`
}

func main() {
    var Data doc
    xml.Unmarshal([]byte(VV), &Data)
    fmt.Println(Data.DocumentType)

}

const VV = `<?xml version="1.0"?>
<ownershipDocument>

    <schemaVersion>X0306</schemaVersion>

    <documentType>4</documentType>

    删除 DocumentType 上的 innerxml 标记,并为其匹配( xml:"documentType" ) . 来自the xml library docs

    如果struct有一个类型为[] byte的字段或带有标签“innerxml”的字符串,则Unmarshal会累积嵌套在该字段中元素内的原始XML . 其余规则仍然适用 .

    您不需要存储未处理的XML . 您正在寻找该字段的值,因此您不需要该标记 .

    Working version

    *编辑:就此而言, ",innerxml" 标签也会打破 SchemaVersion 字段 - 没有匹配的元素(因为 SchemaVersion 是一个字符串),它存储整个文档 .
