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)

What language/tool are you using? From the regex tag info: "Since regular expressions are not fully standardized, all questions with this tag should also include a tag specifying the applicable programming language or tool." — Toto

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

The regex is:

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

Demo & explanation

var test = [
`383 Bukit Timah Road #01-09B Alocassia Apartments Singapore 259727`,
`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`,
`123 blah blah`,
`blah blah 123456`,
`123 blah blah 1234567`
];
console.log(test.map(function (a) {
  return a + ' :' + /^(\d+ [^]*?\b\d{6})$/.test(a);
}));

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

what if i have multiple addresses? it seems to be matching multiple addresses under a single match

I believe does not necessarily have to be but flexible enough to read with/without the new lines

Christiaan Westerbeek Over a year ago

if you want to match multiple instances (addresses in this case) make sure to match as little as possible between the numbers using the ? after the *. So /(\d+ .*?\d{6}\b)/gs
