Re: Access to string/variables per character

substring($copy99,5,5) is the 5th character of  the string, but _why_
are you putting the mathml into a string and then having to access it
characterwise.  MathML is 99% markup so there should be plenty of
chances to add whatever extra punctuation and space you want as you
transform the XML tree into your string, without having to then
modify the string later.
