I have a small problem with a regular expression in javascript
I use this one for putting double quotes around html tags

for example border=0 will became border="0"

unclean = unclean.replace(/ ([^=]+)=([^"' >]+)/gi," $1=\"$2\"");

It searches for = and then put the "" around the html tags

However I have one problem with javascript in html

for example
document.write("<a href=\"javascript:popUp

will became document.write("<a href="\""javascript:popUp
and
document.write("&js=on');
will became 'atedocument.write("&js="on'");

My question is how to escape everthing if it defined into a script tag
<script

Thanks for any help I am really stuck here :)
