我有一個這樣的 XML 文件<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.opentravel.org/OTA/2003/05"> <soap:Header/> <soap:Body> <contents> <article> <category>Server</category> <title>Connect to Oracle Server using Golang and Go-OCI8 on Ubuntu</title> <url>/go-oci8-oracle-linux/</url> </article> <article> <category>Server</category> <title>Easy Setup OpenVPN Using Docker DockVPN</title> <url>/easy-setup-openvpn-docker/</url> </article> <article info="popular article"> <category>Server</category> <title>Setup Ghost v0.11-LTS, Ubuntu, Nginx, Custom Domain, and SSL</title> <url>/ghost-v011-lts-ubuntu-nginx-custom-domain-ssl/</url> </article> </contents> </soap:Body></soap:Envelope>我想修改它只返回這樣<?xml version="1.0" encoding="UTF-8"?> <contents> <article> <category>Server</category> <title>Connect to Oracle Server using Golang and Go-OCI8 on Ubuntu</title> <url>/go-oci8-oracle-linux/</url> </article> <article> <category>Server</category> <title>Easy Setup OpenVPN Using Docker DockVPN</title> <url>/easy-setup-openvpn-docker/</url> </article> <article info="popular article"> <category>Server</category> <title>Setup Ghost v0.11-LTS, Ubuntu, Nginx, Custom Domain, and SSL</title> <url>/ghost-v011-lts-ubuntu-nginx-custom-domain-ssl/</url> </article></contents>所以我想刪除包裝器并只選擇soap:Body 一些使用 etree 的解決方案（https://pkg.go.dev/github.com/beevik/etree#Element）？===========================================================

標準庫足以完成這項任務。簡單地解析 XML 文檔，使用xml:",innerxml"Body 元素在其中使用任意 XML。然后你可以把它吐出來。
package main
import (
"bytes"
"encoding/xml"
"io"
"log"
"os"
)
var src = []byte(`
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.opentravel.org/OTA/2003/05">
<soap:Header/>
<soap:Body>
<contents>
<article>
<category>Server</category>
<title>Connect to Oracle Server using Golang and Go-OCI8 on Ubuntu</title>
<url>/go-oci8-oracle-linux/</url>
</article>
<!-- ... -->
</contents>
</soap:Body>
</soap:Envelope>
`)
type envelope struct {
XMLName xml.Name `xml:"Envelope"`
Body struct {
InnerXML []byte `xml:",innerxml"`
}
}
func main() {
var e envelope
if err := xml.Unmarshal(src, &e); err != nil {
log.Fatal(err)
}
io.WriteString(os.Stdout, xml.Header)
os.Stdout.Write(bytes.TrimSpace(e.Body.InnerXML))
}
