使用colly迭代HTMLElement属性

Question

如HTML结构中所示，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.Attr()这样的函数用于获取单个属性，但我如何迭代所有属性？似乎没有明显的方法从该结构访问attributes或函数。

Answer 1

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)
}
