How to get only internal string without delimiter with .match(regEx) in js?

Question

Hello I am trying to parse an xml string with js. My string is similar to the one below. I am using .match() function with regular expressions.

var str='<rate val="xyz"></rate> <rate val="klm"></rate> <rate val="mnp"></rate>';
var result=str.match(/val="(.+?)"/g);

I want to get a result array like:

 ["xyz","klm","mnp"]

But it gives me as

["rate val="xyz"","rate val="klm"","rate val="mnp""]

How can I get only values without attribute names?

I noticed you reverted my edit -- you shouldn't start your question with "Hello" https://meta.stackoverflow.com/a/351589/6358346 — Grant Foster, Mar 08 '19 at 14:43

Instead of messing with regex, you could use a combination of filter and map to get the properties of the elements in to an array as you require:

var str = '<rate val="xyz"></rate> <rate val="klm"></rate> <rate val="mnp"></rate>';
var result = $(str).filter('rate').map(function() {
    return $(this).attr('val');    
}).get();

console.log(result);
