League of Legends (LoL) Question: How to edit a guide as-is

Something happened and one of the chapters of my guide got deleted. I was proud of this chapter especially and it took a lot of time to make, so I was wondering if there was a way for me to edit the guide as-is so I could retrieve the chapter's BB Code. I can't directly copy from the guide as it just copies text (as far as I know) and images. Any solution to this problem will work.
