I'm collecting meta tag information. I want to get the keywords section out, but just the keywords..not the meta tags itself.

<meta name="keywords" content="one,two,three,four">
[download]

And I want to match anything inside of content="" but nothing else. I tried your s/// but that doesn't work, it made the regex a little worse actually. If I can get it to get the information I want, then the rest of the problems should go away. Thanks.
