Useful snippets reference while using Chrome Developer Tools.
I routinely find myself needing to extract a bunch of content from a website
and paste it in to google sheets. I use xpath in the console a lot for this.
The snippet below makes it easy to print all the data in one line so that I can
easily paste it into sheets and process the data.
console.log($x('//<your xpath>').map(function(el){return el.data.trim()}).join("\n"))
