preg_replace hearthache

[SoundreameR]

Hi guys.. I really hate RegEx, it's a mistery for me how to construct a regex pattern in order to make some changes in a string with preg_replace(). Sooo... here is my problem:

			// clean if tag	
			//need to add somthing HERE
			$item = preg_replace('/<(\/?)(table|tr|td).*?>/is', '<$1$2>', $item);
			print_r($item);

$item carries a html string, actually a html table which will be filtered and parsed into an array. This is a part of an open source class which provides parsing a html table in to an array. But it cleans any code contained in <td> such as <td bgcolor=#FFCC99>. All I need is, before the tags are being cleaned, the bgcolor hex value to be moved inside the table cell.

Example:

If there is <td bgcolor=#FFCC99> in the string somewhere or <td bgcolor=#FFFFFF> no mather of the hex code, it will be replaced with <td>#FFCC99| or like the other example <td>#FFFFFF| so I can later parse the cell content to bgcolor and actual value with something like this explode("|", $string);

I hope my bad english was not fatal on this explanation

Here's one solution, this gets a little touchy because you want 'td' to be there but not be part of the match.

$item = preg_replace('%(?<=td) bgcolor=(#[A-Z]{6})>%', ">$1|", $item);

It's pretty specific to your application, it'll only pick up 'bgcolor' in a 'td' tag. Give that a shot, if it's too specific we can add a few things to make it a little bit more flexible.
