1. 简介在C/C++中，一个比较好的正则表达式是pcre，被很多工具（包括一些商用工具）使用。 2. 源码下载&安装可以从官网http://www.pcre.org/下载，为方便学习，已放在这里http://download.csdn.net/detail/u013344915/7793027。 因为没有VS环境，所以这里就不介绍Windows下面的安装过程。在Linux下面，就是执行典型的3个命令即可：
最后会安装在/usr/local/include,lib等目录中。——本文最后附上整个安装的日志。 当然，不一定要把pcre安装到/usr/local目录，可以自己编译一个lib。在pcre文档中有这方面的介绍，后面有空再补充这一块。 3. 示例在pcre源码中，提供了一个示例代码，即pcredemo.c。但这个仍然有点复杂，所以参考这个文件，下面给出一个更简单的例子。
从日期中提取出年月日：比如从"2014-08-20"中提取出年月日三个信息，即2014,08,20。我们用pcre来实现这个功能。
代码如下： /*
gcc -Wall test-pcre.c -lpcre -o testpcre
or
gcc -Wall test-pcre.c -I/usr/local/include -L/usr/local/lib -lpcre -o testpcre
*/
#include <stdio.h>
#include <string.h>
#include <pcre.h>
#define OVECCOUNT 30 /* should be a multiple of 3 */
int main(int argc,char **argv) {
pcre *re;
const char *error;
char *pattern;
char *date;
int erroffset;
int ovector[OVECCOUNT];
int subject_length;
int rc,i;
pattern = "(d+)-(d+)-(d+)";
date = "2014-08-20";
subject_length = (int) strlen(date);
/*************************************************************************
* Now we are going to compile the regular expression pattern,and handle *
* and errors that are detected. *
*************************************************************************/
re = pcre_compile(pattern,/* the pattern */
0,/* default options */
&error,/* for error message */
&erroffset,/* for error offset */
NULL); /* use default character tables */
/* Compilation failed: print the error message and exit */
if (re == NULL) {
printf("PCRE compilation failed at offset %d: %sn",erroffset,error);
return 1;
}
/*************************************************************************
* If the compilation succeeded,we call PCRE again,in order to do a *
* pattern match against the subject string. This does just ONE match. If *
* further matching is needed,it will be done below. *
*************************************************************************/
rc = pcre_exec(re,/* the compiled pattern */
NULL,/* no extra data - we didn't study the pattern */
date,/* the subject string */
subject_length,/* the length of the subject */
0,/* start at offset 0 in the subject */
0,/* default options */
ovector,/* output vector for substring information */
OVECCOUNT); /* number of elements in the output vector */
/* Matching failed: handle error cases */
if (rc < 0) {
switch (rc) {
case PCRE_ERROR_NOMATCH:
printf("No matchn");
break;
/*
Handle other special cases if you like
*/
default:
printf("Matching error %dn",rc);
break;
}
pcre_free(re); /* Release memory used for the compiled pattern */
return 1;
}
/* Match succeded */
printf("nMatch succeeded at offset %dn",ovector[0]);
/*************************************************************************
* We have found the first match within the subject string. If the output *
* vector wasn't big enough,say so. Then output any substrings that were *
* captured. *
*************************************************************************/
/* The output vector wasn't big enough */
if (rc == 0) {
rc = OVECCOUNT / 3;
printf("ovector only has room for %d captured substringsn",rc - 1);
}
/* Show substrings stored in the output vector by number. Obviously,in a real
application you might want to do things other than print them. */
for (i = 0; i < rc; i++) {
char *substring_start = date + ovector[2 * i];
int substring_length = ovector[2 * i + 1] - ovector[2 * i];
printf("%2d: %.*sn",i,substring_length,substring_start);
}
printf("n");
pcre_free(re); /* Release memory used for the compiled pattern */
return 0;
}

----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/lib
If you ever happen to want to link against installed libraries
in a given directory,LIBDIR,you must either use libtool,and
specify the full pathname of the library,or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information,such as the ld(1) and ld.so(8) manual pages.
