regular.cpp

一套不错的正则表达式库。。短短的

#include "StdAfx.h"
#include "deelx.h"
#include <stdlib.h>
#include <stdio.h>
extern "C" char *find(const char *RegularString, const char *DataString)
{
	char *re = new char(1024);
	CRegexpT<char> regexp(RegularString);//模式
	MatchResult result = regexp.Match(DataString);//待匹配的字符串
	if (result.IsMatched())
	{
		sprintf(re, "%.*s", result.GetEnd() - result.GetStart(), DataString + result.GetStart());
	}
	else
	{
		re = NULL;
	}
	return re;//返回匹配后的结果。
}
