How can I parse Javascript?

[idslamyou]

I want to be able to parse javascript into a post. I have tried to enable HTML for admins, but when I post is just displays the html ,i.e. <script type="text/javascript" src="http://someurlhere.com"></script>
and doesn't get the contents from the javascript. Is there are way to do this?

If not, I also have and XML feed that I can work with, but it is not RSS. Is there a way to parse the XML and have it post into a new thread like the rss feed manager does?
