XRegExp fails under Rhino

[jaquet9]

I am trying to use XRegExp 3.0.0-pre with Rhino 1.6r2 (which is the version of Rhino shipping with Java 6).

Compiling the regex below (taken from http://xregexp.com/ ):

date = XRegExp('(?<year>  [0-9]{4} ) -?  # year  \n' +
               '(?<month> [0-9]{2} ) -?  # month \n' +
               '(?<day>   [0-9]{2} )     # day     ', 'x');

triggers the following error message:

"Invalid quantifier ?" at script line 517 (which is the line: "return augment(new RegExp(key.pattern, key.flags), key.captures, /*addProto*/ true);")

Inspecting key.pattern reveals that the ?<...> are not being stripped out:

(?<year>(?:)[0-9]{4}(?:))(?:)-?(?:)year(?:)(?<month>(?:)[0-9]{2}(?:))(?:)-?(?:)month(?:)(?<day>(?:)[0-9]{2}(?:))(?:)day

Does anyone have a workaround?

@jaquet9, sorry for the long delay. Is it possible to verify whether this is still occurring with the finalized version of XRegExp 3.0.0 and the latest Rhino (currently Rhino 1.7.6)? Thanks!

Will reopen if anyone is able to verify whether this is still failing in Rhino.
