Why does XPath select nodes outside of context node?

Question

I\'m using XPath with Node.js and I have the following HTML document, where I want to select all article nodes and then in a second step all divs with class \"abc\"

Answer 1

You should note that // means search wherever on the page starting from root element while .// means search wherever on the page starting from the current node. So if you want to start search from already found article element you need to replace

"//div[@class='abc']"

with

".//div[@class='abc']"

or

"./div[@class='abc']"

as div is the direct child of article
