Regex - replace with the output of inline javascript in html READ DESCRIPTION!

We need someone to find and replace in a large HTML website all the inline javascript and turn its output into plain clean [login to view URL] example of snippet might look like this: <p>send email at <script type='text/javascript'> <!-- var prefix = 'ma' + 'il' + 'to'; var path = 'hr' + 'ef' + '='; var var123 = 'name' + '@'; var123 = var123 + 'example' + '.' + 'co' + '.' + 'uk'; [login to view URL]('<a ' + path + '\'' + prefix + ':' + var123 + '\'>'); [login to view URL](var123); [login to view URL]('<\/a>'); //-->\n </script>.</p> You will need to find the script in html files and replace with this: <a href="mailto:name@[login to view URL]">name@[login to view URL]</a> *Note that the "var123" has a different name in each source [login to view URL] always contain the letters "var" but different numbers. *We can't share the HTML files so you will need to perform the find and replace via sharescreen on our machines (MAC/Windows 10)
