我正在從 Web 檢索一些 XML，但在提取所需數(shù)據(jù)時遇到問題。這是 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、性別和國家。這是代碼：package mainimport ( "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"`}但每次我運行這個我總是得到這個：main.Artist{Name:"", Gender:"", Country:""}有人可以指出問題出在哪里嗎？

好的，問題是，您沒有充分描述xml要解組的數(shù)據(jù)。你的數(shù)據(jù)看起來更像
struct metadata {
// you need to tag it because go field names can't contain -'s
artists []Artist "artist-list"
}
這樣的事情應(yīng)該有效?；旧希琔nmarshal只會看頂層節(jié)點，而不是走下來尋找結(jié)構(gòu)。
