Um... this doesn't use RE however it returns the date in whatever format you
want and if the date isn't valid it returns the input value... let me know
your thoughts:
<CFSCRIPT>
thisDate = "10 Jan 2asdf005";
endDate = dateReformat('dmy','dmy',thisDate," ");
function dateReformat(formatin,formatout,date) {
thisDelimiter = "/";
if ( Not IsDate(date) ) { return date; }
if ( ArrayLen(arguments) EQ 4 ) { thisDelimiter =
arguments[4]; }
if ( ListLen(date,thisDelimiter) GTE 3 ) {
item1 = Trim(ListGetAt(date,1,thisDelimiter));
item2 = Trim(ListGetAt(date,2,thisDelimiter));
item3 = Trim(ListGetAt(date,3,thisDelimiter));
}
writeoutput(item1 & " | " & item2 & " | " & item3 & "<BR>");
inDate = "";
switch(formatin) {
case "dmy": { day = item1; month = item2; year =
item3; break; }
case "mdy": { day = item2; month = item1; year =
item3; break; }
case "ymd": { day = item3; month = item2; year =
item1; break; }
}
writeoutput(day & " | " & month & " | " & year & "<BR>");
writeoutput(outDate);
switch(formatout) {
case "dmy": { outDate =
DateFormat(inDate,'dd/mm/yyyy'); }
case "mdy": { outDate =
DateFormat(inDate,'mm/ddyyyy'); }
case "ymd": { outDate =
DateFormat(inDate,'yyyy/mm/dd'); }
}
return outDate;
}
</CFSCRIPT>
You could even add the shortDateMask function from cflib to it and then you
could output based on locale... overkill I think...

Actually, you we're right I only scrolled down to (?=) if I scrolled down a
bit more I would have seen (?:)
I'll see on Monday if (:/|-) will do the trick for me.
What I'm doing is creating a function that reformats a date, i.e. from
mm/dd/yyyy to dd/mm/yyyy etc..

Although, in the regexp your working with... what does it matter if it
captures them or not? Given the subexpression you're using, it's always
going to match SOMETHING, or the whole regexp is going to fail, so if you
get a match at all, you know the third and fifth subexpressions returned are
going to be either a slash or a dash. Equally, they're going to be the same
length (ie: 1), you can safely assume that fact too. I can see no gain from
doing a look-ahead.
I think you're making your life hard for yourself.
What exactly are you trying to do (other than matching a date, that is).
