sequential numbers in a string to an array

Question

I have a string that has sequential numbers such as the following:

1. this is some text 2. this is more text 3. this is even more text

I'd like to split this into an array that starts with the numbers:

['1. this is some text', '2. this is more text', '3. this is even more text']

I tried the following:

string.split(/(?=\d[.][ ])/g);

This works well when the numbers are 1-9. However, when the numbers >=10, it doesn't work well.

Any ideas on how to get this to work?

Yes, this is all you need to change (try on JSFiddle):

string.split(/(?=\b\d+[.] )/g);

The + after the \d tells it to match 1 or more.

EDIT: The \b is a word boundary to ensure you're getting the number from the beginning, not each separate digit.

This doesn't work for me. 9 works fine, but it splits 10 like this: [...,'9. text goes here', '1', '0. the text for ten goes here', '1', '1. the next for eleven goes here']

@Marc: sorry about that, but the \b word boundary check I just added should do the trick.
