Hi Alban, and many thanks for your input. > My first question is why you’re using a recursive CTE here? This doesn’t appear to be hierarchical data (such as a tree), unless perhaps you intended to actually traverse the HTML document hierarchy? This is basically an exercise on my part. The question that I'm trying to answer is here: https://stackoverflow.com/questions/70574881/how-can-get-html-inner-tag-in-posgresql I've already answered it in 3 different ways - but I was trying to do it with RCTEs in order to improve my comprehension of them. So, basically, I want to pick out a subsection of text from a "passage". So then, I wanted to establish a true/false state for the lines that I want and don't want, going through line by line. I know that the RCTE is a very contrived way of doing this, but it's for learning really. I wonder if you could be so kind as to give me a "skeleton" RCTE for this - I've been staring at this for hours - and it's not that I'm lazy or haven't studied RCTEs - I wrote this RCTE https://stackoverflow.com/a/71674990/470530 recently, so it's not as if I'm completely ignorant of RCTEs - I'm just stuck in a rut. Any help would be appreciated. TIA and rgs, Pól... > Alban Hertroys
