在GO我使用以下结构和代码解码

type XMLLink struct { 
 
\t XMLName xml.Name `xml:"link"` 
 
\t Rel  string `xml:"rel,attr"` 
 
\t Href string `xml:"rel,href"` 
 
} 
 
type XMLEntry struct { 
 
\t XMLName xml.Name `xml:"entry"` 
 
\t Link []XMLLink `xml:"link,attr"` 
 
} 
 
type XMLFeed struct { 
 
\t XMLName xml.Name `xml:"feed"` 
 
\t Entry []XMLEntry `xml:"entry,attr"` 
 
}

这里我想解码条目标签下的链接标签。以下为i使用与XML解码成必要的值

var feed XMLFeed 
 
//response got from http request is expected xml here which is already men tioned above 
 
bodyBytes, _ := ioutil.ReadAll(response.Body) 
 
\t \t \t err := xml.Unmarshal(bodyBytes, &feed) 
 
\t \t \t if err != nil { 
 
\t \t \t \t log.Fatalf("Unable to unmarshall", err) 
 
\t \t \t } 
 
\t \t \t fmt.Println("number of entries:", feed)

但这里输出的代码只 数目的条目：{{http://www.w3.org/2005/Atom饲料} []} 不知道这里出了什么问题，请提出任何更改，以使此工作正常

答

这里的问题是，您正在使用attr你笑的地方uldn't。

您正在将XMLEntry和XMLLink标记视为属性。
