如何从xml(包括标记)中提取完整的html?

我有 the following code

package main

import (
    "encoding/xml"
    "fmt"
)

func main() {
    xr := &xmlResponse{}

    if err := xml.Unmarshal([]byte(x), &xr); err != nil {
        panic(err)
    }

    fmt.Printf("%+v", xr)
}

type xmlResponse struct {
    //Title string `xml:"title,omitempty"`
    Title struct {
        BoldWords []struct {
            Bold string `xml:",chardata"`
        } `xml:"bold,omitempty"`
        Title string `xml:",chardata" `
    } `xml:"title,omitempty"`
}

var x = `<?xml version="1.0" encoding="utf-8"?>
<mytag version="1.0">
  <title><bold>Go</bold> is a programming language. I repeat: <bold>Go</bold> is a programming language.</title>
</mytag>`

这将输出:

&{Title:{BoldWords:[{Bold:Go} {Bold:Go}] Title: is a programming language. I repeat:  is a programming language.}}

如何获得:

<bold>Go</bold> is a programming language. I repeat: <bold>Go</bold> is a programming language.

换句话说,我不仅需要标签,还需要把它们放在适当的地方,而不仅仅是一片粗体。尝试像字符串一样获取它(例如,取消xmlResponse结构中第一个“Title”的注释)会完全忽略粗体项。
