more regex questions

[Anon]

Basically, my problem is that I need to grab the name = value attribute pairs of custom elements that I have created in a text file. For example, the element tag may look like this:
<insert img="filename.jpg" title="title of image" artist="artist name" medium="image medium" caption="...">

I have created a regular expression that matches this and other variants:
$pattern = "/<insert(?:\s+([^{\s])\s=\s\"([\"])\")*>/x";}

What I am trying to do there is store each name and value as seperate elements (hence the parentheses) the problem is that it only stores the last occurence of the name value pair of each element. So if i had two elements it would store the caption and the ... in the array of matches twice. Is there any way that I can get it to seperate them in the first stage, or will I have to create two regular expressions and perform a preg_match_all twice. I'm new to regular expressions and to PHP so any advice would really be appreciated. Thanks

I don';t think you can do it in one step. You have to get the "insert" out of the way first:

$string = "<insert img=\"filename.jpg\" title=\"title of image\" artist=\"artist name\" medium=\"image medium\" caption=\"...\">";

$pattern = '/<insert((\s+[^{=]+\s=\s"["]"))>/';}

preg_match ($pattern, $string, $matches);

preg_match_all('/(\s+([^{=]+)\s=\s"(["]*)")/',} $matches[0], $p);

foreach ($p[2] as $e) {
echo $e . "<BR>";
}

echo "<BR>";

foreach ($p[3] as $e) {
echo $e . "<BR>";
}
