Javascript Split Regular Expression Keep The Delimiter

Using JavaScript I'm trying to split a paragraph into it's sentences using regular expressions. My regular expression doesn't account for a sentence being inside brackets and I w

Solution 1:

I took the match approach rather than split. It could be tighter (e.g. what if a sentence ends with ..., etc).

text.match(/\(?[A-Z][^\.]+[\.!\?]\)?(\s+|$)/g);

Solution 2:

@Utkanos You idea is good, but I think replace may better:

text.replace(/\(?[A-Z][^\.]+[\.!\?]\)?/g, function (sentence) {
    output += '<p>'+ sentence + '</p>';
});

You no need to loop again.

Solution 3:

use the (?=pattern) lookahead pattern in the regex example

varstring = '500x500-11*90~1+1';
string = string.replace(/(?=[$-/:-?{-~!"^_`\[\]])/gi, ",");
string = string.split(",");

this will give you the following result.

[ '500x500', '-11', '*90', '~1', '+1' ]

Can also be directly split

string = string.split(/(?=[$-/:-?{-~!"^_`\[\]])/gi);

giving the same result

[ '500x500', '-11', '*90', '~1', '+1' ]
