returns substrings that match the regular expression in supplied string after an offset It applies regular expression to target_str with offset. This function returns a vector containing 2 elements for first match of the pattern and if there a sub expressions : 2 elements for each of subexpression match. The first (even numbered) element of each pair is the start index and the second (odd numbered) is the end index of the match. The regexp_parse function is more efficient than regexp_match and regexp_substr, because it doesn't allocate strings. Where: 2-14 is a range matched by whole expression, 2-4 is a range where '(2[34])' is matched , and 12-14 is a range where '(2[35])' subexpression matched.
