Question

I’m currently scraping a website and have all the useful data I need, although it comes with a bit of data that I don’t want.

Example:

<h2>Heading</h2>
<p>Useful <a href="/foo">data</a></p>
Rubbish <a href="/bar">data</a>
<h2>heading</h2>

So essentially I want to remove all text that is not enclosed by either h2 or p tags.

Is there an easy function/preg?

Answer 1

Results are alittle better:

preg_match_all('~<h2>.*?<\/h2>|<p>.*?<\/p>~i', $str, $new);
