Last Modified: 2012-06-27
I need a simple PHP or javascript script that parses an html page returned as a string, when it finds a name tage that doesn't have an id tag between the < > creates an id attribute with the same name as name="objectname".  Anybody have any idea how to do this?

Here the PHP code you needs

$str = "<html><body><div name=\"something\"><div name=\"something2\" id=\"test\"></div></div></body></html>";

$re  = "/<([^\s>]+) ([^>]+)>/";

if (preg_match_all($re, $str, $match)){

	foreach ($match[2] as $k => $attr_str){

		$attrs = explode(" ", $attr_str);

		$id_found = false;

		$name     = "";

		foreach ($attrs as $attr){

			if (substr($attr, 0, 3) == "id="){

				$id_found = true;



			if (substr($attr, 0, 5) == "name="){

				$name = substr($attr, 5);

				echo "Found name:" . $name;



		if (!$id_found && $name != ""){

			$current_tag = $match[0][$k];

			$new_tag = substr($current_tag, 0, -1) . " id=" . $name . ">";

			$str = str_replace($current_tag, $new_tag, $str);




echo "Result:\n" . $str;

Here's a js solution:



			for(i in document.body.all)


				if(document.body.all[i].name != "" && document.body.all[i].id == "")

					document.body.all[i].id = document.body.all[i].name;





			for(f in document.forms)


				for(e in document.forms[f].elements)


					if(document.forms[f].elements[e].name != "" && document.forms[f].elements[e].id == "")

						document.forms[f].elements[e].id = document.forms[f].elements[e].name;
