.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty margin-bottom:0;
Imagine I have this text (I realise using regex to parse HTML is not the correct solution...)
<div><p>HELLO1</p>
<span>SPIDER</span></div>
<div><p>HELLO2</p>
<span>CHEESE</span></div>
<div><p>HELLO3</p>
<span>BANANA</span></div>
I want to match text inside the <p> and <span> respectively (this is a contrived example)
I can achieve that by using:
/<p>(.*?)</p>.*?<span>(.*?)</span>.*?</div>/gsmi
However, I don't want to match if the text inside the span is CHEESE.
Ive tried to use a negative lookahead like so:
/<p>(.*?)</p>.*?<span>((?!CHEESE).*?)</span>.*?</div>/gsmi
However, that now matches the wrong thing as the pattern matches to HELLO2 and BANANA where I want HELLO3 and BANANA
I realise this is because Im using .*? but this is required for the real life solution.
Example here: https://regex101.com/r/h4YgDm/3
How can I match, a whole pattern only but still spanning multiple lines?

You could achieve what you want in two steps. First, extract the div elements which meet the criteria (ie. no CHEESE) like this (demo):
<div>(?:(?!CHEESE).)*?</div>
Second, select the content between p and span tags as two groups (demo):
(?<=<p>)(.*?)(?=</p>)(?:.*?)(?<=<span>)(.*?)(?=</span>)
