pcre 匹配 C 中的所有组 [英] pcre match all groups in C

问题描述

我想使用 PCRE C 库递归匹配一个组.

I want to match a group recursively using PCRE C library.

例如

pattern = "(\d,)"
subject = "5,6,3,2,"
OVECCOUNT = 30

pcrePtr = pcre_compile(pattern, 0, &error, &erroffset, NULL);
rc = pcre_exec(pcrePtr, NULL, subject, (int)strlen(subject), 
0, 0, ovector, OVECCOUNT);

rc 为 -1..

如何匹配所有组，使得匹配的是5,", 6,", 3,", 2,"

How to match all groups so that matches are "5,", "6,", "3,", "2,"

以此类推，PHP 的 preg_match_all 会解析整个字符串，直到主题结束...

For analogy, PHP's preg_match_all parses entire string until the end of subject...

推荐答案

我使用 strtok 的任何方式，因为 "," 在每组之后重复..

Any way I used strtok since "," was repeating after each group..

欢迎使用 pcre 的解决方案....

Solution using pcre is welcomed....
