golang XML not unmarshal-ing

I have the following XML:

<wb:sources page="1" pages="1" per_page="50" total="28" xmlns:wb="http://www.worldbank.org">
  <wb:source id="11">
    <wb:name>Africa Development Indicators</wb:name>
    <wb:description />
    <wb:url />
  </wb:source>
  <wb:source id="31">
    <wb:name>Country Policy and Institutional Assessment (CPIA) </wb:name>
    <wb:description />
    <wb:url />
  </wb:source>
</wb:sources>

My code for parsing the XML:

     type Source struct {
	Id   string `xml:"id,attr"`
	Name string `xml"wb:name"`
}

type Sources struct {
	XMLName xml.Name `xml"wb:sources"`
	Sourcez []Source `xml"wb:source"`
}
    
    func GetSources() (*Sources, error) {
    	resp, err := http.Get(sourcesUrl)
    	if err != nil {
    		log.Fatalf("error %v", err)
    		return nil, err
    	}
    
    	defer resp.Body.Close()
    	s := new(Sources)
    	body, err := ioutil.ReadAll(resp.Body)
    	if err != nil {
    		log.Print(err)
    		return nil, err
    	}
    	log.Printf("body %v", string(body))
    
    	xml.Unmarshal(body, &s)
    	return s, nil
    
    }

My code:

    sources, err := GetSources()
    	if err != nil {
    		log.Panic()
    	}
    
    	fmt.Printf("%v ", sources)

Keep returning &{{http://www.worldbank.org sources} []} what I'm I doing wrong?

You should not use wb: in the structs.

Here is your example simplified and working:
http://play.golang.org/p/fphHokLprT

Changed the structs to:

type Source struct {
	Name        string `xml:"name"`
	Description string `xml:"description"`
	Url         string `xml:"url"`
}

type Sources struct {
	XMLName    xml.Name `xml"sources"`
	SourceList []Source `xml:"source"`
}

and it worked!!
