Hi guys I am new to the regex for some patterns matching i have wrote the regex but it is very lengthy regex so i was hoping that any one can help me optimize it ?
My REGEX-->
(T)(\d{9})(T)(\s{0,19}\d{0,19}\s{0,19}[0-9DO ]\d{0,19}\s{0,19}[OD0-9 ]\s{0,19}\d{0,19}\s{0,19}\d{0,19}[0-9D ]\d{0,19})(O)(\s{0,5}\d{0,19})\b
Pattern I want to match -->
T062102098T0741 0361212401O
T011900571T 000007250107O1274
T065000090T203 93 5797 9O 4037
T325170628T0108626004D18O01054
T071108452T 42D896D5O 3587
T041211609T 01D1270DD4O 2721
T021407912TO9196D00580D6O 7106
T081219108T O45D936D4O 3155
T074909988T O022D853 6O 1340
Pattern I am avoiding -->
T071904779T154505122619 2051
T065000090T000 32 493O9O 11007
So any help would be great .Thanks in advance.
Your RegEx is fine, rather it could be simplified (perhaps optimized) as below:
One thing I have found in your RegEx, is unnecessary use of
(...)
. Moreover, using\s{0,19}
or\s{0,5}
could be simply written as\s*
. The last one is better, only if you're not restricted to use of0-19
times or0-5
times.
