php - preg_replace - Replacing <br> with nothing in <pre> tags


I have the following:

$newtext = preg_replace('@<pre>.*<br[/>]*?>?</pre>@si','',$text);

and I want it to replace all<br>, <br />, or <br/> tags with nothing when between<pre> tags, but it isn't working. What's wrong with it?




Your problem is that you're trying to use regular expressions to do a parser's job. Even if you get it mostly working, you'll be finding edge cases where things break down the road.
