Yeah, i know, it's a bit complicated isn't it.  Slapping a </p> on the 
end isn't enough because there could be a load of unfinished tags - for 
example, half a p tag with half an a tag inside it.  Anything really. 
That's why ideally i would just consider the inner content of tags and 
when it comes to tags inside tags, either remove them completely or 
leave them as they are.  This seems like such a common thing on the net, 
to have a short section followed by 'read more' for example, that i 
thought there would be an easy way to do it.
