Re: [pcre-dev] regexp does not work , but does work on other…

when i  run the code i allways getting 2 subgroups when i expect to
get only one
the "link" (index.html)
if i add this code ( and modify my abit) .
#include <stdio.h>  //meat and potatoes
#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;
int erroffset;
int ovector[OVECCOUNT];
int rc;

char *regex = "<a[^>]+href\\s*=\\s*[\"']?([^\"'> ]+)";
char *data  = "<a href=\"index.html\">PCRE index page</a>";
re = pcre_compile(
                regex,   /* the pattern */
                0,   /* default options */
                &error,   /* for error message */
                &erroffset,        /* for error offset */
                NULL);             /* use default character table */
if (! re)
{
    fprintf(stderr, "PCRE compilation failed at expression offset %d:
%s\n", erroffset, error);
    return 1;
}

rc = pcre_exec(
                re,             /* the compiled pattern */
                NULL,       /* no extra data - we didn't study the pattern */
                data,    /* the subject string */
                strlen(data),   /* 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 */
if (rc < 0)
{
    switch(rc)
    {
        case PCRE_ERROR_NOMATCH:
        printf("No match found in text\n");
        break;
    /*
        More cases defined...
    */
        default:
        printf("Match error %d\n", rc);
        break;
         return 1;
    }
}
const char **stringlist;
int i;
 int result_match = pcre_get_substring_list(data, ovector, rc, &stringlist);
 if (result_match < 0)
    printf("get substring list failed %d\n", result_match);
 else
    {
    for (i = 0; i < rc; i++)
      printf("%2dL %s\n", i, stringlist[i]);
    if (stringlist[i] != NULL)
      printf("string list not terminated by NULL\n");
    /* free((void *)stringlist); */
    pcre_free_substring_list(stringlist);
    }
