But, in example 2, seems like "year" should be repeat<1,4>, but: year= repeat<1,2> works:
cregex date = (month= repeat<1,2>(_d)) // find the month ...
(delim= (set= '/','-')) // followed by a delimiter ... (day= repeat<1,2>(_d)) >> delim // and a day followed by the same delimiter ... (year= repeat<1,2>(_d >> _d)); // and the year.
actually, repeat<1,3> works for month, day, and year. Am I mixed up on what "repeat" means?
repeat<n,m>(X) means to match X between n and m times, inclusive. So matching a month a day, you want repeat<1,2>(_d) to match 1 or 2 digit characters, and to match a year, you want repeat<1,2>(_d >> _d) to match two digits or four digits. Three digits isn't a common representation of a year. HTH, -- Eric Niebler Boost Consulting www.boost-consulting.com
