Regex to match groups in any order

I have the following regular expression:
^\s*<\s*script\s*name\s*=\s*["](?<name>[^"]*)["]\s* platform\s*=\s*["](?<platform>[^"]*)["]\s*(deferred\s*=\s*["](?<deferred>[^"]*)["])?>\s*$

Open in new window

It matches fine against the following:
<script name="FOO" platform="all">
<script name="FOO" platform="all" deferred="yes">
However, I need it to match regardless of the order of the parameters so it should also match:
<script name="FOO" deferred="yes" platform="all">
 -- and --
<script platform="all" deferred="yes" name="FOO">
How do I rewrite the above Regex so that it will match each name-value pair regardless of what order they appear?

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hi,

pls try
^((?=\s*<\s*script[\s\S]*?platform\s*=\s*["](?<platform>[^"]*)["])(?=\s*<\s*script[\s\S]*?name\s*=\s*["](?<name>[^"]*)["]))(?=\s*<\s*script[\s\S]*?deferred\s*=\s*["](?<deferred>[^"]*)["])[\s\S]*?>$

Almost. Except in my original expression the deferred parameter was optional.
Rgonzo1971Commented:
then try
*?platform\s*=\s*["](?<platform>[^"]*)["])(?=\s*<\s*script[\s\S]*?name\s*=\s*["](?<name>[^"]*)["])(?(?=\s*<\s*script[\s\S]*?deferred(\s*=\s*["])(?<deferred>[^"]*))|)[\s\S]*?[^>]*?>$
