What I want to do is extract all the text from in between a pair or
tags
(<td>...</td> for example). I know I could use a rangeOfString: call
to get
the first one, but then I have to create a new string with the
remaining
data and call rangeOfString: again to get the next and on and on until
the
whole string is parsed. I hope there is a better way to do this.
You could use - (NSRange)rangeOfString:(NSString *)subString
options:(unsigned)mask range:(NSRange)aRange, which at least eliminates
the need to create a new string each time. Just bump the range up each
time and do two searches, one for '<td' and another for '</td>'.

P.S. I left the ending '>' off in case the td tag had attributes, but
that's probably better handled by regex...
