Cannot extract correct data from XML in GO

I am retrieving some XML from the web, but I am having problem extracting the data that I need. This is the 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>

I want to extract the name, gender and country. This is the code:

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"`
}

But everytime I run this I always get this:

main.Artist{Name:"", Gender:"", Country:""}

Can someone point where the problem is ?
Thanks.

Okay, the problem is, you haven't adequately described the data for xml to unmarshal. Your data looks more like

struct metadata {
    // you need to tag it because go field names can't contain -'s
    artists []Artist "artist-list"
}

Something like that should work. Basically, Unmarshal is only going to look at the top-level nodes, not walk down looking for a structure.
