sorry Nick, as stated in your previous post, whitespace and end of lines.
This should cover the 4 possiblities:
"thing"
" thing"
"thing "
" thing "
var re = new RegExp("(^|\\s)" + className + "(\\s|$)")
or better still, use this get elements by class function you mentioned
then process the elements:
