How to extract Heading tags in PHP from a string?
domparser, php, text-extraction
Solution
If you actually want to use regular expressions, I think that:
preg_match_all('/<h[0-6]>([^</h[0-6]>*)</h/i', $string, $matches);
should work as long as your header tags are not nested. As others have said, if you're not in control of the HTML, regular expressions are not a great way to do this.
Problem
From a string that contains a lot of HTML, how can I extract all the text from `<h1><h2>etc` tags into a new variable? I would like to capture all of the text from these elements and store them in a new variable as comma-delimited values. Is it possible using `preg_match_all()`?
