用colly迭代HTMLElement属性？

Question

如HTML结构所示，属性是一个私有属性：

// 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
}

有一些函数可以用于获取单个属性，但是我如何迭代所有属性呢？似乎没有明显的方法从该结构访问attributes或函数。

通过访问下面的原始html.Node，我们可以迭代：

for _, node := range e.DOM.Nodes {
    fmt.Println(node.Attr)
}
