The pcre_exec() function finds ONE match only. It stops when it has
found one match. Therefore:

Call pcre_exec(). It returns the offset of the first match. Extract any
substrings that you need. Then call pcre_exec() again, setting the
startoffset argument beyond the first match, and the PCRE_NOTBOL option.
It will return the offset of the second match ... and so on.
