Cannot Select Direct Child from *goquery.Selection

Question

In jQuery and CSS, you can use the > character which points to only the direct child element.

This works in Goquery with something like doc.Find("body > ul"), but when you already have a *goquery.Selection and you want to select a direct child element of the selection, how can this be done?

For example:

doc.Find("body > ul > li") // Works

doc.Find("body > ul > li").Each(func(i int, s *goquery.Selection) {
    s.Find("> ul") // Does not work
})

I want to accomplish what you'd expect to be selected from the second block of code but I haven't had any success with this.

How can this be done?

As noted in this cascadia ticket (the selector library that goquery uses), this functionality is not (and will not be) implemented.

The simplest workaround would be to use the ChildrenFiltered() method on your selection:

doc.Find("body > ul > li").Each(func(i int, s *goquery.Selection) {
    s.ChildrenFiltered("ul")
})

@Acidic: Does this help you? – Aug 30 '17 at 14:38
yep, that's the solution. Thanks! – Ari Seyhun Sep 11 '17 at 06:40
Actually I'm having trouble with this again, it seems like `ChildrenFiltered` still captures deep children when I only want to restrict it to direct children. – Ari Seyhun Jan 10 '18 at 05:43
@Acidic: please post a reproducible example of HTML and Go code of this behaviour. – Jan 10 '18 at 11:32
Great answer, thanks. Comparing https://github.com/andybalholm/cascadia/issues/18 and https://github.com/PuerkitoBio/goquery/issues/117 was very frustrating! – Ben Parsons Jan 30 '19 at 15:12
