say I have some groups of text lines that each group of lines have identical pattern except in the 3rd line there is an optional unique pattern that may or may not be present


Acct1, to be paid [12345upto16Dgit]
amout: $587.11 when: 2007-10-11 reference #: 1345
From: some named account[1234..8To14Digt] $687.99

Acct2, to be paid [12345upto16Dgit]
amout: $127.11 when: 2009-10-11 reference #: 1345
From: some other named account acct Bal2beDetermined[1234..8To14Digt]

trid with regex options ignore, explicit capture, Single line:

but that missed the one without acctBal
however if I remove the last lien of pattern , I will get them all

aha, got it

(?<AcctName>\r\n[A-Z]{2,40}([',]{0,1})( \w*[,.'-]{0,1}[A-Z]{0,40})*) \[(?<AcctNbr>\d*)\] +
.{2,4}amount: \$(?<Amt>{{money}})( {2,6})when: (?<DtPmt>{{yyyy-mm-dd}}) + reference #: (?<RefNbr>\d{4,8}) +
.{2,6}From: \w*(\s\w*)* \[\d{8,14}\]( \$(?<FromAcctBal>{{money}}) ){0,1}


instead of
(?<AcctName>\r\n[A-Z]{2,40}([',]{0,1})( \w*[,.'-]{0,1}[A-Z]{0,40})*) \[(?<AcctNbr>\d*)\] +
.{2,4}amount: \$(?<Amt>{{money}})( {2,6})when: (?<DtPmt>{{yyyy-mm-dd}}) + reference #: (?<RefNbr>\d{4,8}) +
.{2,6}From: \w*( \w*){2,10} \[\d{8,14}\]( \$(?<FromAcctBal>{{money}}) ){0,1}
