Is there a way to get the index of the current a[href] element?

[hsluoyz]

I want to know the index of the current a[href] element for the page, as follows.

c.OnHTML("a[href]", func(e *colly.HTMLElement) {
	index := ...
	fmt.Println("This is %d-th hyperlink for this page", index)
})

Is there a way to do it? Thanks.

You can get it by calling e.DOM.index()

@asciimoo , but I printed it out, it's not correct. See the following output. The indentation shows the depth. The meaning of [x-y-z] is:

• x: request ID
• y: the actual index of <a href=“xx”></a> I manually recorded
• z: e.DOM.index()

Most values of e.DOM.index()are 0, sometimes 1. This is not correct.

I've added HTMLElement.Index, please verify that it fixes the issue.

It works. Thanks for the quick fix!
