使用正则表达式捕获文本

Question

I have a text where I need to capture the second group

Response on your Property Listing 
Dear Rahul Bond, 
A user is interested in your Property, ID 62455995: 2 BHK , Multistorey 
Apartment in Raheja Vihar , Mumbai. 
Details of Contact Made: 
Sender's Name: Test (Individual) 

The text to be retrieved is 2 BHK, Multistorey Apartment in Raheja Vihar, Mumbai. This does start with **A user is interested in your Property, ID xxxxxxx: **

A user is interested in your Property, ID 62455995: 2 BHK , Multistorey 
    Apartment in Raheja Vihar , Mumbai. 

The expected output is 2 BHK, Multistorey Apartment in Raheja Vihar, Mumbai.

I have tried with .match(/(A user is interested in your Property, ID.*[^:]) (.*\n.*)/g) Unfortunetly it gives me all 2 lined text.

Answer 1

You can use this regex:

 const text = `Response on your Property Listing Dear Rahul Bond, A user is interested in your Property, ID 62455995: 2 BHK, Multistorey Apartment in Raheja Vihar, Mumbai. Details of Contact Made: Sender's Name: Test (Individual)`; const rgx = /(?<=A user is interested in your Property, ID \d+: )(.*\n.*)/g; const result = text.match(rgx); console.log(result);

Answer 2

From the above comment...

"How about more generically looking for... ID , followed by a whitespace (sequence), followed by a sequence of 8 digits, followed by a single colon, followed by another whitespace (sequence) and then capturing anything which is not a dot/period including the first occurring dot/period... /ID\s+\d{8}\:\s+(?<description>[^.]+\.)/g "

... and making use of the proposed regex...

 const multilineText = `Response on your Property Listing Dear Rahul Bond, A user is interested in your Property, ID 62455995: 2 BHK, Multistorey Apartment in Raheja Vihar, Mumbai. Details of Contact Made: Sender's Name: Test (Individual)`; // see... [https://regex101.com/r/uDFHaV/1] const regX = /ID\s+\d{8}\:\s+(?<description>[^.]+\.)/g; // either... console.log( [...multilineText.matchAll(regX)].map(({ groups: { description } }) => description) ); // or... console.log( [...multilineText.matchAll(regX)] [0]?.groups.description ); //... or... console.log( regX.exec(multilineText)?.groups.description );
