在C ++中有一个使用模式匹配（使用正则表达式）的函数吗？

Question

There is a simple C++ method to use pattern matching on strings? The code should sound like this:

if (regexpcmp("l?nole*[0-9]", "linoleum1")) {
  //we have a match!
} else {
   //no match 
}

Answer 1

Did you already look at Boost.Regex ?

const boost::regex e("l?nole*[0-9]");
if (regex_match("linoleum1", e)) {
  //we have a match!
} else {
  //no match 
}

Answer 2

Not in the core language. Use Boost.Regex or an external library like pcre . In a unix environment you almost certainly have access to the BSD regular expression tools ( regcomp , regerror , regexec , regfree ) which are c-like rather than c++-like but do work.

Answer 3

Take boost.regex friend. if you are not allowed to use boost (sadly, there are still companies doing this), you could look into pcrecpp , which is a C++ binding developed by google for the famous PCRE library.

Answer 4

如果您使用最常用编译器的最新版本，则可以在TR1名称空间中使用标准正则表达式库（基于boost :: regex）：std :: tr1 :: regex。
