How to find a string that follows after the first "of" of a range-CodePudding

I have the following string

... of 7th July 2019 , signed by the District Director of the National Service of ENCAC.

I wish to find

the National Service of ENCAC

I have this regular expression to search from "signed by" , but I would like it to search from the first "of" that follows "signed by"

(?<=signed by)(.*)(?=\.)

Thank you very much in advance for your help.

CodePudding user response：

You could match until the first occurrence of of after signed by instead of looking back with a lookbehind, then use a capture group and match the trailing dot.

\bsigned by\b.*?\bof\b\s([^.]*)\.

If there can also not be a dot in between:

\bsigned by\b[^.]*?\bof\b\s([^.]*)\.
