goquery, how to remove child

How to remove child nodes in goquery?

I'm trying 3 different ways to remove child nodes in my sample code,

https://github.com/suntong/kuaizh/blob/master/crawler/kijiji.go

as I can't quite figure it out from the doc: 

 titleHtml, _ = title.RemoveFiltered("a").Html()
 locationHtml, _ = location.RemoveClass("date-posted").Html()
 descriptionHtml, _ = description.Find("div").Remove().Html()

However, none of them is what I'm expecting. Basically all three contains sub nodes that I want to remove, and I want the end result to be the html without the removed nodes. 

Check out the full source code, or its execution result for details. 

Thanks
