Create a regex to delete data in between

Question

I am having the below given data

Mr. SIM Kamsath, Vice President & Branch Manager
Tel: +855 (0)12 922 660, +855 (0)15 900 269
E-mail: getemail(\'acledabank.c         


        

Answer 1

Your description is not very clear what you want for the first entry, where E-mail line is not available. I assume you don't want to extract anything from the first entry.

E-mail: getemail\('([^']*)','[^']*'\)([^@]*@\1)(.+)?\r?\n(?:(P.O. .*)\r?\n)?(Tel: .*)?

Demo on regex101 (I wrote the pattern to make it compatible with even JavaScript).

High level break down of the regex:

• E-mail: getemail\('([^']*)','[^']*'\)([^@]*@\1)(.+)?\r?\n matches the email line, and use the content from the argument to getemail as hint to separate the email from the text that comes after. I assume there is no percentage escape in the string literal of getemail.

• (?:(P.O. .*)\r?\n)? matches optional P.O. Box line

• (Tel: .*)? matches optional Tel line.

Capturing groups:

• Group 2 contains the email address.
• Group 3 contains the text after the email address.
• Group 4 contains the P.O. Box line.
• Group 5 contains the Tel line.

(I wrote group 3 as (.+)? to make the group return null/undefined when nothing follows the email address, instead of (.*) which will return an empty string).

Answer 2

E-mail:(?=(?:(?!E-mail)[\s\S])*P.O. Box)\s\S*\.([\s\S]*?)(?=Fax)

Try this.Grab the capture.See demo.
