Re: two regexp related questions

For 2), if you're using the regex to both validate the input (making
sure it conforms to the required syntax) and parse/extract the
name/value pairs, you might be able to make the job easier by breaking
these two tasks apart.  Use the regex as you have it now to validate
the input and then, if it matches, use a shorter regex that matches
just a single name/value pair with analyze-string to do the actual
processing.
