Hello I have just made this regex and tested using this tool
http://gskinner.com/RegExr/

I am trying to match (x)html, xml & html4.0 in group so that I may return

$matches[0] // the full tag
$matches[1] // the start tag including any attribs etc
$matches[2] // the tag name
$matches[3] // the innerHTML or data inside the tag "excluding HTML" (needs to be optional)
$matches[4] // an optional endtag (needs to be optional)

this is my current regex and I think it's okay hehe
CODE([\w].+)?(</[a-zA-Z0-9]+?>)[/CODE]

im using it with

preg_match_all("/(<([\w]+)[^>]*>)([\w].+)?(</[a-zA-Z0-9]+?>)/", $htmldoc, $matches, PREG_SET_ORDER);

PHP returns this error

Warning: preg_match_all() [function.preg-match-all]: Unknown modifier '[' in /var/www/PgEditor/class.php on line 18

plz help its doin my box in

    You need to escape the / in the middle and add s modifier if newlines are between the tags.

    preg_match_all("/(<([\w]+)[>]*>)([\w].+)?(<\/[a-zA-Z0-9]+?>)/s", $htmldoc, $matches, PREG_SET_ORDER);

      unfortunately that is not returning any data now lol, thanks alot though, I think for the system i want to implement regex is insufficient anyway, thanks loads.

        Dont worry I am rewriting the tag parser using xml to array heres what I have so far

        <?php
    echo"hello world!";
?>

        pmsl nah only joking I have this

        <?php
	class tagparse
	{
		private $data;
		private $vals;
		function tagparse($DATA, $WHITE=1)
		{
			$index = array();
			$this->data = trim($DATA);
			$this->data = str_replace("&nbsp;", "[tagparse::space]", $this->data); // fix for &nbsp;
			$this->data = preg_replace("/(<(\w+).*?>)(<\/\\2>)/", "\\1[tagparse::empty]\\3", $this->data); // fix for empty tags that do not use ommittag
			$this->vals = array();
			$parser = xml_parser_create();
			xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);
			xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, $WHITE);
			if ( !xml_parse_into_struct($parser, $this->data, $this->vals, $index) )
				die("XML error: ".xml_error_string(xml_get_error_code($parser))." at line ".xml_get_current_line_number($parser));
			xml_parser_free($parser);
			/*
			 * The code below is all for using of &nbsp; and empty tags that do not use ommittag
			 */
			$this->data = str_replace("[tagparse::space]", "&nbsp;", $this->data);
			$this->data = str_replace("[tagparse::empty]", "", $this->data);
			for($i = 0;$i<count($this->vals);$i++)
			{
				if(isset($this->vals[$i]['value']))
				{
					if(strstr($this->vals[$i]['value'], "[tagparse::space]") !== false)
						$this->vals[$i]['value'] = str_replace ("[tagparse::space]", "&nbsp;", $this->vals[$i]['value']);
					if(strstr($this->vals[$i]['value'], "[tagparse::empty]") !== false)
						$this->vals[$i]['value'] = str_replace ("[tagparse::empty]", "", $this->vals[$i]['value']);
				}
			}
		}
		function outputString()
		{
			$output = "";
			for($i = 0;$i<count($this->vals);$i++)
			{
				//output whole array into formatted file
				$indent = $attribs = "";
				if($this->vals[$i]['level'] > 1)
					$indent = str_repeat("\t", $this->vals[$i]['level']-1);
				if(isset($this->vals[$i]['attributes']))
				{
					foreach($this->vals[$i]['attributes'] as $key=>$val)
					{
						$attribs.= " ".$key."=\"".$val."\"";
					}
				}
				switch($this->vals[$i]['type'])
				{
					case "open":
						$output .= $indent."<".$this->vals[$i]['tag'].$attribs.">\r\n";
					break;
					case "complete":
						$ommittag = "";
						if(!isset($this->vals[$i]['value']))
							$output .= $indent."<".$this->vals[$i]['tag'].$attribs." />"."\r\n";
						else
							$output .= $indent."<".$this->vals[$i]['tag'].$attribs.">".$this->vals[$i]['value']."</".$this->vals[$i]['tag'].">"."\r\n";
					break;
					case "close":
						$output .= $indent."</".$this->vals[$i]['tag'].">\r\n";
					break;
				}
			}
			return $output;
		}
		function outputArr()
		{
			return str_replace("1", "", print_r($this->vals));
		}
	}
