Your regular expression then becomes a match for the 'mycode' tags, and you can immediately follow it up with another preg_replace () to turn the 'mycode' tags into 'pre' tags after you're done htmlentitizing the content.

I wrote about this on <a href="http://coreyworrell.com/blog/article/convert-to-html-entities-between-code-tags" rel="nofollow">my blog</a> but the only real way to do it is to use an XML parser.

If this is a possible usecase, you might use a regex like this :/<pre.*?>(.*?[<pre.*?>.*<\/pre>]*)<\/pre>/imsuThe tags got stripped in my first comment, sorry about that, if htmlentities show up in the regex, replace them with the good characters …but it still wouldn’t handle the case of having a single closing pre tag inside another pre. Could someone manage to write a regex which would handle this case ?The function name (pre_entities) should be between quotes otherwise it will throw a notice. Beware that having a pre tag inside another pre tag would leave you with one pre opening and two pre closings. If this is a possible usecase, you might use a regex like this :

/<pre.*?>(.*?[<pre.*?>.*<\/pre>]*)<\/pre>/imsu
