Regex to remove all tags from a web page

[xavier.bury at clearstream.com]

Alex


The trick i used in my discrete browser was to treat <scripts> and 
<styles> first.

String anything between those two tags and you're a lot safer. Eventually 
if you need those back, keep them out of the tag stripping operation and 
put them back after.

Then deal with the html structure...
