BBCode Regex: Lista desordenada

thunder.scripts · #1 (**permalink**) 23/06/2006, 19:59

Estoy necesitando una expresión regular que haga las veces de parser de bbcode, más específicamente para transformar listas como esta en html:

Código:

[lista]
*opcion
*opcion[/lista]

Código:

<ul>
<li>opcion</li>
<li>opcion</li>
</ul>

Estuve buscando un rato pero encontré soluciones bastantes complejas que involucraban varias funciones y que además servían para varios tipos de listas. Hay alguna forma de crear una expresión regular para resolver esta tarea?

Muchas gracias
Fede

bajate el foro phpbb de phpbb.com y mira el codigo fuente del archivo function_posts.php y ahi estan las funciones que vos necesitas.

creo que la funcion que andabas buscando son estas (analizalas bien porque copie y pegue tal cual las usan los foros phpbb)

Código:

function bbencode_second_pass($text, $uid)
{
	global $lang, $bbcode_tpl;

	$text = preg_replace('#(script|about|applet|activex|chrome):#is', "\\1:", $text);

	// pad it with a space so we can distinguish between FALSE and matching the 1st char (index 0).
	// This is important; bbencode_quote(), bbencode_list(), and bbencode_code() all depend on it.
	$text = " " . $text;

	// First: If there isn't a "[" and a "]" in the message, don't bother.
	if (! (strpos($text, "[") && strpos($text, "]")) )
	{
		// Remove padding, return.
		$text = substr($text, 1);
		return $text;
	}

	// Only load the templates ONCE..
	if (!defined("BBCODE_TPL_READY"))
	{
		// load templates from file into array.
		$bbcode_tpl = load_bbcode_template();

		// prepare array for use in regexps.
		$bbcode_tpl = prepare_bbcode_template($bbcode_tpl);
	}

	// 
Código:

	 and
  for posting code (HTML, PHP, C etc etc) in your posts.
	$text = bbencode_second_pass_code($text, $uid, $bbcode_tpl);

	//  Cita:   and
 
  for posting replies with quote, or just for quoting stuff.
	$text = str_replace("[quote:$uid]", $bbcode_tpl['quote_open'], $text);
	$text = str_replace("[/quote:$uid]", $bbcode_tpl['quote_close'], $text);

	// New one liner to deal with opening quotes with usernames...
	// replaces the two line version that I had here before..
	$text = preg_replace("/\[quote:$uid=\"(.*?)\"\]/si", $bbcode_tpl['quote_username_open'], $text);

	//[list]
and[list=x]
for (un)ordered lists.
	// unordered lists
	$text = str_replace("[list:$uid]", $bbcode_tpl['ulist_open'], $text);
	// li tags
	$text = str_replace("[*:$uid]", $bbcode_tpl['listitem'], $text);
	// ending tags
	$text = str_replace("[/list:u:$uid]", $bbcode_tpl['ulist_close'], $text);
	$text = str_replace("[/list:o:$uid]", $bbcode_tpl['olist_close'], $text);
	// Ordered lists
	$text = preg_replace("/\[list=([a1]):$uid\]/si", $bbcode_tpl['olist_open'], $text);

	// colours
	$text = preg_replace("/\[color=(\#[0-9A-F]{6}|[a-z]+):$uid\]/si", $bbcode_tpl['color_open'], $text);
	$text = str_replace("[/color:$uid]", $bbcode_tpl['color_close'], $text);

	// size
	$text = preg_replace("/\[size=([1-2]?[0-9]):$uid\]/si", $bbcode_tpl['size_open'], $text);
	$text = str_replace("[/size:$uid]", $bbcode_tpl['size_close'], $text);

	//  and  for bolding text.
	$text = str_replace("[b:$uid]", $bbcode_tpl['b_open'], $text);
	$text = str_replace("[/b:$uid]", $bbcode_tpl['b_close'], $text);

	//  and  for underlining text.
	$text = str_replace("[u:$uid]", $bbcode_tpl['u_open'], $text);
	$text = str_replace("[/u:$uid]", $bbcode_tpl['u_close'], $text);

	//  and  for italicizing text.
	$text = str_replace("[i:$uid]", $bbcode_tpl['i_open'], $text);
	$text = str_replace("[/i:$uid]", $bbcode_tpl['i_close'], $text);

	// Patterns and replacements for URL and email tags..
	$patterns = array();
	$replacements = array();

	// [img]image_url_here[/img] code..
	// This one gets first-passed..
	$patterns[] = "#\[img:$uid\]([^?].*?)\[/img:$uid\]#i";
	$replacements[] = $bbcode_tpl['img'];

	// matches a xxxx://www.phpbb.com code..
	$patterns[] = "#\[url\]([\w]+?://([\w\#$%&~/.\-;:=,?@\]+]|\[(?!url=))*?)\[/url\]#is";
	$replacements[] = $bbcode_tpl['url1'];

	// www.phpbb.com code.. (no xxxx:// prefix).
	$patterns[] = "#\[url\]((www|ftp)\.([\w\#$%&~/.\-;:=,?@\]+]|\[(?!url=))*?)\[/url\]#is";
	$replacements[] = $bbcode_tpl['url2'];

	// phpBB code..

y esta otra, (aca atenes todos los regex tambien

function bbencode_first_pass($text, $uid)
