How to push certain strings from an huge string into array

Question

This might sound weird, but i want to parse a xml response by pushing certain string with following regular expression:

data-href="[\d\w\/:\.\=]*[">]?

into an array.

The reason for this is just for testing. A friend has built a webpage with jimdo where he displays a image gallery. now i want to try parsing the xml on this site and only fetch the images which are at every data-href tag and use them in my react native app.

Any ideas?

Why not just use the String.match method?

var matches = xml_str.match(/data-href="[\d\w\/:\.\=]*[">]?/g);

Edit: if you want to just get the URL within the href, use regex capture groups:

var matches = xml_str.match(/data-href="([\d\w\/:\.\=]*)[">]?/g);
console.log(matches);

You can then map the matches array to only contain the element with the URL.

Thanks mate. But i am doing something wrong in my code. If i test the xml response with regex101.com it looks great, but if i do this in my code i get a weird match response. Maybe it is correct, but how would u push every "data-href" in the response into a array?

Sorry, you have to put a global flag after the end delimiter in JS. I updated my answer. If you're still having trouble, save and post your regex101 link so I can check it out.

Thanks bro. It works here https://regex101.com/r/c3yiYX/2, but not in my code. I get null in my code now

thanks mate. i updated by removing /d and then i just saw that i am not allowed to use the regEx in a string which i should have seen before!!! .match(/data-href="([\d\w\/:\.\=]*)[">]?/g); not .match("/data-href="([\d\w\/:\.\=]*)[">]?/g");

@BigPun86—yes you can, just quote the quotes, e.g. .match(/data-href=\"([\w\/:\.\=]*)[\">]?/g);. Posting code as a runnable snippet helps ensure that it actually works. ;-)
