Hey everyone! I'm trying to understand a weird behavior in my tag search function. I start by finding an opening HTML element with the class `test-div`, and then I want to find its corresponding closing tag by checking for the same level of indentation (same number of leading spaces). To handle whitespace, I replace tabs with four spaces. Here's where it gets confusing: the opening tag has 8 spaces in front of it, but the closing tag on line 9 has 12 spaces before it. Surprisingly, when I use `startsWith` to check for a match, it returns true for the closing tag on line 9, even though the indentation is different. I expected the closing tag to be on line 10, which has 8 spaces, matching the opening tag. Can anyone explain how `startsWith` could possibly match in this case? Is there a subtle detail I'm missing about string comparison or whitespace handling?

I think the issue might lie in the way your code interacts with the `getDataEditor()` function. When I ran a similar setup without that dependency, the closing tag found was on the correct line. Make sure to check how input and dependencies are handled, as that could be where the mismatch is happening. Your given input may not be the exact same in the hidden parts of your code.
Have you double-checked the string you’re passing to `startsWith`? Sometimes, the issue can stem from not having the right variable or having hidden whitespace in there. I recommend simplifying your code by breaking things into variables for clarity, making debugging easier to pinpoint any issues.
Honestly, if your input is confirmed correct after all checks, the problem can easily lie somewhere outside this function. Simplify and isolate your test cases before assuming it's a framework issue or bug.
Just a heads up, using regex to parse HTML isn’t the best practice. Instead, you should try using `DOMParser` and `querySelector`. They can handle your requirements more reliably, and it’ll save you from getting caught in whitespace issues like this.
