XML 標(biāo)簽應(yīng)該正確打開和關(guān)閉。從您發(fā)布的 XML 來(lái)看，似乎 XML 聲明并非一開始。
<?xml version="1.0" encoding="utf-8"?>
這應(yīng)該是一開始的。希望這可以幫助

有問(wèn)題的 XML 似乎是錯(cuò)誤的，
這是正確版本的 XML 文件和 Go 代碼
XML文件：
<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">

示例 Go 代碼
package main
import (
"io/ioutil"
"encoding/xml"
"fmt"
)
type Rss2 struct {
ItemList []Item `xml:"channel>item"`
}
type Item struct {
Title string `xml:"title"`
Link string `xml:"link"`
Description string `xml:"description"`
PubDate string `xml:"pubDate"`
GUID string `xml:"guid"`
}
func main() {
r := Rss2{}
xmlContent, _ := ioutil.ReadFile("example2.xml")
if err := xml.Unmarshal(xmlContent, &r); err != nil {
panic(err)
}
fmt.Println("RSS item :", r)
}
現(xiàn)在，您可以迭代并在 XML 中找到所需的數(shù)據(jù)。
