Hi. I'm having problem with regular expressions.
In a bbcode parser I'm using I'm trying to ad list-tags. The problem is that I can't close ordered lists properly. This is the expressions I use to match list items.
'/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[\*(?::\w+)?\](.*?)(?=(?:\s*<br\s*\/?>\s*)?\[\*|(?:\s*<br\s*\/?>\s*)?\[\/?list)/si' => "\n<li class=\"bb-list\">\\1</li>",
'/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[\/list(:(?!u|o)\w+)?\](?:<br\s*\/?>)?/si' => "\n</ul>",
'/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[\/list:u(:\w+)?\](?:<br\s*\/?>)?/si' => "\n</ul>",
'/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[\/list:o(:\w+)?\](?:<br\s*\/?>)?/si' => "\n</ol>",
'/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[list(:(?!u|o)\w+)?\]\s*(?:<br\s*\/?>)?/si' => "\n<ul class=\"bb-ul\">",
'/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[list:u(:\w+)?\]\s*(?:<br\s*\/?>)?/si' => "\n<ul class=\"bb-ul\">",
'/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[list:o(:\w+)?\]\s*(?:<br\s*\/?>)?/si' => "\n<ol class=\"bb-ol\">",
'/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[list(?::o)?(:\w+)?=1\]\s*(?:<br\s*\/?>)?/si' => "\n<ol class=\"bb-ol bb-decimal\">",
'/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[list(?::o)?(:\w+)?=i\]\s*(?:<br\s*\/?>)?/s' => "\n<ol class=\"bb-ol bb-lower-roman\">",
'/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[list(?::o)?(:\w+)?=I\]\s*(?:<br\s*\/?>)?/s' => "\n<ol class=\"bb-ol bb-upper-roman\">",
'/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[list(?::o)?(:\w+)?=a\]\s*(?:<br\s*\/?>)?/s' => "\n<ol class=\"bb-ol bb-lower-alpha\">",
'/(?<!\\\\)(?:\s*<br\s*\/?>\s*)?\[list(?::o)?(:\w+)?=A\]\s*(?:<br\s*\/?>)?/s' => "\n<ol class=\"bb-ol bb-upper-alpha\">",
I'm not exactly sure, but my guesses are that line 4 is up to something... That it won't match. I would be very glad if someone could point out whats wrong to a par of sleepy eyes.
