我正在从 Web 检索一些 XML,但在提取所需数据时遇到问题。这是 XML:
<metadata xmlns="http://musicbrainz.org/ns/mmd-2.0#" xmlns:ext="http://musicbrainz.org/ns/ext#-2.0" created="2013-04-13T16:54:01.107Z">
<artist-list count="2" offset="0">
<artist id="35dac7d2-0b1f-470f-9a5a-c53c8821f6d6" type="Person" ext:score="100">
<name>Eric Prydz</name>
<sort-name>Prydz, Eric</sort-name>
<gender>male</gender>
<country>SE</country>
</artist>
</artist-list>
</metadata>
我想提取姓名、性别和国家。这是代码:
package main
import (
"encoding/xml"
"fmt"
"io/ioutil"
"net/http"
)
func main() {
client := &http.Client{}
req, _ := http.NewRequest("GET", "http://www.musicbrainz.org/ws/2/artist/?query=artist:Fred", nil)
res, _ := client.Do(req)
bs, _ := ioutil.ReadAll(res.Body)
var artist Artist
xml.Unmarshal(bs, &artist)
fmt.Printf("%#v\n", artist)
}
type Artist struct {
Name string `xml: "name"`
Gender string `xml: "gender"`
Country string `xml: "country"`
}
但每次我运行这个我总是得到这个:
main.Artist{Name:"", Gender:"", Country:""}
有人能指出问题出在哪里吗?
谢谢。
