I'm having a bit of trouble trying to acheive something, maybe someone

I presume using a reg expression is the best way to achieve this, I'm
just not sure of how to word an expression to scan for only characters
within the html tags.
You're just asking for a headache if you try to match paired and

but it gets ugly fast and you need a very capable regular expression
engine like Oniguruma from Ruby1.9)
