Converting strings to html safe

Hello list,

   I am trying to convert some strings to html versions for a specific 
renderer that doesn't like getting "&" or "<" part way through a 
sentence. What I need to do is turn things like "&" into "&amp;". Is 
there a ready made function for this? I've search the list and 
documentation in XCode but haven't found the right thing yet, 
possibly my search terms aren't correctly phrased. I'd rather use a 
pre-made function than making my own large Switch statement incase I 
miss out one case.

And no, I don't have control over the renderer, it's Google Earth :-)

Cheers,
   Craig
