conversion between Boost.Xpressive and Boost.RegEx

[Barry]

I used Boost.Xpressive after 1.3.4, and found it interesting and
helpful, but I suffer from long complie-time. So I wonder there is a
way to write the regular expression in Xpressive and use it in
Boost.RegEx, since there grammer is simmilar to use

If you want to use dynamic regexes with xpressive (the string-based
kind), you can improve compile times by only including all of xpressive
in one file, which has one function in it that accepts a string and
returns a basic_regex<obj ect. Everywhere else, only include the files
that you need for what you're doing, such as basic_regex.hpp ,
match_results.h pp and regex_algorithm .hpp.

HTH,
