Parsing data with regular expression in javascript

Question

I'm trying parse data to variable. Data are represented as string in format like this :

code          time
0.00000       3.33333
1.11111       4.44444
2.22222       5.55555

I'm using match method to retrive all words and numbers in to array:

result = mystring.match(/(\w+)/g);

Words like code and time are match good but I have problem with numbers which are splitted to 2 numbers.

What I would like to achieve is this :

\w doesn’t include .. It looks like you actually just want non-whitespace, \S. — jonrsharpe

Let's use split for this and split on all whitespaces.

var match = document.querySelector("pre").textContent.split(/\s+/g); 

console.log(match);

<pre>
code          time
0.00000       3.33333
1.11111       4.44444
2.22222       5.55555
</pre>

Reversed with match works too

var match = document.querySelector("pre").textContent.match(/\S+/g); 

console.log(match);

<pre>
code          time
0.00000       3.33333
1.11111       4.44444
2.22222       5.55555
</pre>
