知道为什么这种解析在直接从站点访问 XML 时不起作用，而当我将其复制并粘贴到 var 时它起作用吗？
package main
import (
"encoding/xml"
"fmt"
"strings"
"io/ioutil"
"net/http"
)
type Sitemapindex struct {
Locations []Location `xml:"channel>item"`
}
type Location struct {
Loc string `xml:"title"`
}
func (e Location) String () string {
return fmt.Sprintf(e.Loc)
}
func main() {
resp, _ := http.Get("https://www.sec.gov/Archives/edgar/xbrlrss.all.xml")
bytes, _ := ioutil.ReadAll(resp.Body)
string_body := string(bytes)
var s Sitemapindex
decoder := xml.NewDecoder(strings.NewReader(string_body))
decoder.Strict = false
decoder.Decode(&s)
fmt.Println(s)
}
