C++/STL string: How to mimic regex like function with wildcards?

问题

I would like to compare 4 character string using wildcards.

For example:

std::string wildcards[]=
{"H?  ", "RH? ", "H[0-5]  "};
/*in the last one I need to check if string is "H0  ",..., and "H5  " */

Is it possible to manage to realize only by STL?

Thanks, Arman.

EDIT:

Can we do it without boost.regex?
Or should I add yet another library dependences to my project?:)

回答1:

Use Boost.Regex

回答2:

No - you need boost::regex

回答3:

Regular expressions were made for this sort of thing. I can understand your reluctance to avoid a dependency, but in this case it's probably justified.

You might check your C++ compiler to see if it includes any built-in regular expression library. For example, Microsoft includes CAtlRegExp.

Barring that, your problem doesn't look too difficult to write custom code for.

回答4:

You can do it without introducing a new library dependency, but to do so you'd end up writing a regular expression engine yourself (or at least a subset of one).

Is there some reason you don't want to use a library for this?
