Problem with WordPress messing up HTML with P and BR tags.

Maybe you don't want to disable wpautop but you are sick of WordPress adding

and
tags to your included html.

A solution is to open up wp-includes/formatting-functions.php and modify the wpautop function. In this version, you can make wpautop respect any tags you want. Just add them!

Usage

Simply add your tag name inside the variable below, using the same tag-pip-tag format:

   //WP Version 2.0.4
   function wpautop($pee, $br = 1) {
           $allowedTags = 'table|thead|tfoot|caption|colgroup|tbody|tr|td|th|div|dl|dd|dt|ul|ol|li|pre| select|fieldset|legend|form|blockquote|address|math|p|h[1-6]';
           $allowedCloseTags = 'option|select|p|li|div|dl|dd|dt|th|pre|td|ul|ol';

//WP Version 2.2.3
   function wpautop($pee, $br = 1) {
           $pee = $pee . "n"; // just to make things a little easier, pad the end
           $pee = preg_replace('|
s*
|', "nn", $pee);
           // Space things out a little
           $allblocks = '(?:table|thead|tfoot|caption|colgroup|tbody|tr|td|th|div|dl|dd|dt|ul|ol|li|pre|select|form|map|area|blockquote|address|math|style|input|p|h[1-6]|hr)';

ATTENTION

If you mess up WordPress and can't get anything to work, you should have made a backup! Sorry!
