I'm somewhat surprised that the template class doesnt have that
function, but Prototype already has a function called
String.extractScripts(). If you know regular expressions then it
should be easy to write a String.extractTemplateSymbols() function by
replacing ScriptFragment with your own SymbolFragment.
I'm a little rusty on my regular expressions, but here's my crack at
it:
SymbolFragment = "(?:#{)(\w+)(?:})"
Hope that helps,
RR
