/<<.+.txt>>/gm

g is for global (will search through entire source)

m is for multi line search support

Part of the issue is that the string you've specified wouldn't match because the second > is missing in <<45.txt>.

Also, you're using the . (dot) selector, and also trying to find a period. It works, but now how you think it is.

Here's the regex you want:

var regex = /<<\d+\.txt>>/g

\d matches only numbers

\. matches an actual period

/g means global, so it won't stop at the first match

Practice Regular Expressions

Demo

var string = "<<12.txt>> <<45.txt>>";
var regex = /<<\d+\.txt>>/g;
var matches = string.match(regex);

console.log(matches);

P.S., if you actually want to match with 1 > or 2 >>, you can with:

var regex = /<<\d+\.txt>>?/g

? optionally matches the character right before it
