Regex: how to extract text until end of string with multiple new lines?

Question

I want it to match each of the text and flexible enough to read multiple lines instead of a single line.

Text single input example

383 Bukit Timah Road #01-09B Alocassia Apartments Singapore 259727

Text with multiple lines example

383 Bukit Timah Road 
#01-09B Alocassia Apartments 
Singapore 259727

448 Ang Mo Kio 
Avenue 10 #01-1693 
Singapore 560448

383 Bukit Timah Road 
#01-09B Alocassia Apartments 
Singapore 259727

Regex:

(\d+ .*\d{6}\b)

Answer 1

What you're looking for is the s flag (single line: dot matches newline). https://regex101.com/r/ZTP1hC/1

Answer 2

Use [^] (specific to JavaScript Regex) to match any character including linebreaks

The regex is:

^(\d+ [^]*?\b\d{6})$
