我试图解组以下代码，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"?>

删除innerxml上的DocumentType标记，并为其指定要匹配的元素的名称（xml:"documentType"）。来自the xml library docs：
如果结构具有类型为
[]byte或string且带有标记＆＃34;的字段，则innerxml＆＃34;，Unmarshal会累积嵌套在该字段中的元素内的原始XML 。其余规则仍然适用。
您不需要存储未经处理的XML。您正在寻找该字段的价值，因此您不需要该标记。
*编辑：就此而言，",innerxml"标记也会打破SchemaVersion字段 - 没有匹配的元素（因为SchemaVersion是一个字符串），它会存储整个文件。
