The best answer on StackOverflow: Using RegEx to parse HTML
I need to match all of these opening tags: <p> <a href="foo"> But not self-closing tags: <br /> <hr class="foo" /> I came up with this and wanted to make

SO in a nutshell:
"I need to do X"
"Have you tried Y?"
"No, because I don't need Y, I need X."
"Well you can do Z if you can't do Y."
"OK, sure. But how do I do X?"
"Why do you need to do X?"
(Explains why in my hyper-specific situation, I need to do X, and Y and Z won't work)
This question has been marked as a duplicate of "How to do Y"
Except in 99% of cases the person is asking an xy problem, and if they ever explained the why, they would get a proper answer.
Often the reason no one does the hyper-specific thing, is that there are better non code solutions, it's massively insecure, or is just stupid micromanaging.
You know, when I typically ask a question on SO, its because I want to learn how that thing works, or how to write it myself. I usually say as much, but the SO folks are too focused on the ends, they completely neglect the means. Chances are I'm already aware of that no-code solution, but that's not what I'm asking for.
I think there's an element of responsibility that some people feel when they respond. If you're asking for a very niche solution that is likely to create other problems in the future, should anyone else look at your code or refactor it or rely on it, or should you forget how it works, perhaps people are going to be less inclined in helping you craft it.
If you still want to craft it, that's okay, but you have to expect that some real percent of the answers are going to be those folk who know what the tried and true solution is, often because they've lived through the reality that you're attempting to create and they've dealt with the aftermath of doing it special and different.
Which is fine when people do not reject the answers that are different from what they were expecting. Learning that the problem you have is a reason that noone does this, is a valid thing to learn.
It's usually when I see people moving the goal posts on replies, or complaining that they didn't answer the exact question that i see as frustrating. Or "I don't want to do that" with no more info.
But if you are aware of other solutions, you should state that in the question and give your reasons. It's a waste of time if you know someone might suggest what you have dismissed already.
The html question is a classic for this, they want to find non self closed tags. Why? Why can't they use a parser? What are they doing with this info? All questions that would give you a good idea on how the problem can be solved. Playing with regex would be a valid answer to that, but is not stated. Unfortunately I find so's format discourages extra interrogation.
The answer is not an attack on the person, but a frustration at the people before that ignored previous answers to use a parser.
and if they ever explained the why, they would get a proper answer.
That's funny, every time I've explained in detail why my question isn't a duplicate nobody fucking cares and it still gets closed.
I would say it's more like: "How can I do X?" "Here are some reasons you can't do Y."
The answers should have been "Here are some reasons doing X is hard, but here's an attempt at it anyway and also some more robust alternatives to doing X." That would have been an excellent answer. (If you go down far enough you do start to see things like this but they're hindered by people still responding that you can't do Y or downvoting because they don't understand what's happening.)
More like:
- How can I do X?
- Marked as duplicate of "How can I do Y?"
Edit: I've got insomnia and don't have my glasses on and misread the end.
Always start SO questions with X/Y problem pre-empting
These people are everywhere and will stop at nothing to make you click on one of these

They are trying to derail your question, which was already a generalized version of what your actual question was. And of course, you would need to explain everything you generalized out of your question (which would probably all get deleted by someone editing your question and removing all the irrelevant facts) by which point your question becomes so complicated nobody can answer it, even though they could have answered the generalized version.
My advice, just use chatgpt or mistral, 99% you will get a better answer than stackoverflow. And you will get this actionnable answer IMMEDIATELY !
