Regex for extracting price from html as text

Question

So there's some html as string like:

     3.399<sup>99</sup> <span>Dineros</span> bla bla

or even

     3,399<sup>99</sup> <span>Dollars</span> bla bla

and I need some regex that applied to this string would give:

["3399", "99"]

so that I can eventually get a Number from the integer and decimal part

The obligatory [regex to parse html, why not](http://stackoverflow.com/questions/590747/using-regular-expressions-to-parse-html-why-not), and quesions showing not even minimal effort are off-topic — baao, Mar 14 '17 at 11:20

Ah, I use - Questions asking as "why isn't this code working..." - but too broad would also apply @evolutionxbox — baao, Mar 14 '17 at 11:23

Use String#match method to fetch the strings and using Array#map method generate the number array by replacing the dot or comma.

var str = '3.399<sup>99</sup> <span>Dineros</span> bla bla';

console.log(
  str
  // get the pattern matching substrings
  .match(/\d+(?:[.,]\d+)?/g)
  // iterate and generate the Number
  .map(function(d) {
    // parse the generated string
    return Number(
      // replace the dot or comma
      d.replace(/[.,]/, '')
    )
  })
)

I like this, but assumes all numbers in some HTML is desired. – evolutionxbox Mar 14 '17 at 11:25
there was a previous answer with a regex like `/\d+(?:[\.,]\d+)?/g`, is there any notable difference? – Andrei Roba Mar 14 '17 at 11:33
@RobyRodriguez : `(?:` for non-capturing - both would provide same, since there is global flag match will not store the captured value – Pranav C Balan Mar 14 '17 at 11:34
