remove unwanted styles from objects using jquery (or php)?

[fROMOHIO]

I was wondering if there was any way of removing unwanted style attributes from objects (p, ul, li etc), as for some reason my client has decided to copy/paste information from word into a wysiwyg and doesn't bother removing the crap that comes along with it, I was wondering if jquery could do this?Here's an example of the outputted code (which varies obviously depending on what they've copied/pasted from)\[code\]<ul style="list-style-type: disc;"><li style="margin: 0.0px 0.0px 0.0px 0.0px; line-height: 21.0px; font: 12.0px 'Lucida Grande';">Residential Class 1/ New Buildings</li><li style="margin: 0.0px 0.0px 0.0px 0.0px; line-height: 21.0px; font: 12.0px 'Lucida Grande';">Residential Class 1/ Best Renovation</li><li style="margin: 0.0px 0.0px 0.0px 0.0px; line-height: 21.0px; font: 12.0px 'Lucida Grande';">Resorts, including apartments and aged care</li><li style="margin: 0.0px 0.0px 0.0px 0.0px; line-height: 21.0px; font: 12.0px 'Lucida Grande';">Public or Commercial Buildings</li><li style="margin: 0.0px 0.0px 0.0px 0.0px; line-height: 21.0px; font: 12.0px 'Lucida Grande';">Interior Fitout
