How to get these images alt tag url with regex

Question

I have a bunch of HTML code which contain these images:

<img alt=\"http://www.adsf1.net/static/1231.jpg\" width=\"100%\">
<img alt=\"http://www.1322.com/files/150818g58.jpg\" width=\"100%\">
<img alt=\"http://www.aerwef.org/sda/sdfawe.jpg\" width=\"100%\">

I manage to match these images with this regex

<img[^>]+\s*\/?>

But, I would like to get the url from the alt tag using JS, and store it into an array.

I would like to get a JS array like this (based on the above example)

["http://www.adsf1.net/static/1231.jpg", "http://www.1322.com/files/150818g58.jpg", "http://www.aerwef.org/sda/sdfawe.jpg"]

That isn't HTML what you have there. Why are you trying to use regex instead of DOM methods? — PeeHaa, Aug 18 '15 at 14:47
@PeeHaa Isn't that regex the fastest way to match a certain pattern? Using DOM methods seems to be a bit troublesome. — user3781968, Aug 18 '15 at 14:57
@VasiliyVanchuk that's the problem, the website I want to parse use alt instead of src. — user3781968, Aug 18 '15 at 14:57
@adeneo Sorry for asking it. Which is the right tool for parsing HTML? DOM? — user3781968, Aug 18 '15 at 14:58

You can try this regex :

<img alt=\\"(http[^"]*)\\".*

Hope this helps.
