英文:
Iterate over HTMLElement attributes with colly?
问题
如在HTML结构中所见，attributes是一个私有属性：
// HTMLElement是HTML标签的表示。
type HTMLElement struct {
// Name是标签的名称
Name string
Text string
attributes []html.Attribute
// Request是元素的HTML文档的请求对象
Request *Request
// Response是元素的HTML文档的响应对象
Response *Response
// DOM是页面的goquery解析的DOM对象。DOM是相对于当前HTMLElement的
DOM *goquery.Selection
// Index存储当前元素在由OnHTML回调匹配的所有元素中的位置
Index int
}
有一些函数，比如.Attr()用于获取单个属性，但是如何遍历所有属性呢？似乎没有明显的方法来访问attributes或该结构的函数。
英文:
As seen in the HTML struct, the attributes is a private property:
// HTMLElement is the representation of a HTML tag.
type HTMLElement struct {
// Name is the name of the tag
Name string
Text string
attributes []html.Attribute
// Request is the request object of the element's HTML document
Request *Request
// Response is the Response object of the element's HTML document
Response *Response
// DOM is the goquery parsed DOM object of the page. DOM is relative
// to the current HTMLElement
DOM *goquery.Selection
// Index stores the position of the current element within all the elements matched by an OnHTML callback
Index int
}
There are functions such a .Attr() for fetching a single attribute, but how would I iterate over all attributes? It seems that there is no obvious way to access attributes or functions from that struct.

通过访问底层的html.Node，我们可以进行迭代：
for _, node := range e.DOM.Nodes {
fmt.Println(node.Attr)
}
英文:
By accessing the raw html.Node underneath, we can iterate:
for _, node := range e.DOM.Nodes {
fmt.Println(node.Attr)
}
