正则表达式提取字符串之间的数据

Question

Ive tried the ff regex below but it does not seem to work. I wanted to extract data between F. Prepaids and G. Initial Escrow Payment and get the ff sample result below. Thanks.

#my regex

(?<=F. Prepaids)[\S\s]*?(?= G. Initial Escrow Payment)

#String

F. Prepaids $887.01
01 Homeowner's Insurance Premium ( 12 mo.) toAmerican Family  $893.00
Insura
02 Mortgage Insurance Premium (     mo.)
03 Prepaid Interest ($5.99 per day from 10/02/2020 to 10/01/2020) -$5.99
04 Property Taxes (     mo.)
05
06
07
08
G. Initial Escrow Payment at Closing $3,776.11

If i got the data in between I also want a regex to get the ff result which other data includes new lines based on the strin above.

Homeowner's Insurance Premium ( 12 mo.) to American Family Insura
Mortgage Insurance Premium ( mo.)
Prepaid Interest ($5.99 per day from 10/02/2020 to 10/01/2020)
Property Taxes (     mo.)

Any idea with this one ? Thnk you.

Answer 1

You may use

(?m)(?<=F\. Prepaids[\s\S]*?^\d+ )[^\r\n]+(?:\r?\n[^\n\d][^\r\n]*)?(?=[\s\S]*?\nG\. Initial Escrow Payment)

See the regex demo

Details

• (?m) - multiline mode on
• (?<=F\\. Prepaids[\\s\\S]*?^\\d+ ) - match a location immediately preceded with F. Prepaids , then any zero or more chars as few as possible, then 1+ digits at the start of a line and then a space
• [^\\r\\n]+ - any one or more chars other than CR and LF and
• (?:\\r?\\n[^\\n\\d][^\\r\\n]*)* - zero or more sequences of CRLF or LF ending, any non-digit and non-newline char and then any zero or more chars other than a newline and carriage return
• (?=[\\s\\S]*?\\nG\\. Initial Escrow Payment) - the current location must be followed with
  • [\\s\\S]*? - any zero or more chars as few as possible
  • \\n - a newline
  • G\\. Initial Escrow Payment G\\. Initial Escrow Payment - a G. Initial Escrow Payment text.
