.split() and .replace() a string value to filter out the desired text in JavaScript

Question

I am trying to filter out the hashtags in a text string, by splitting it, and removing unwanted HTML tags.

I'm not getting the correct output, and I am not too sure where I am making my mistake, and would appreciate your guidance.

This is an example of the text string value:

"<a href=\"https://twitter.com/search?q=fnb\" target=\"_blank\">#fnb</a>, <a href=\"https://twitter.com/search?q=mobilesimcard\" target=\"_blank\">#mobilesimcard</a>, <a href=\"https://twitter.com/search?q=what\" target=\"_blank\">#what</a>, <a href=\"https://twitter.com/search?q=refugeechild\" target=\"_blank\">#refugeechild</a>"

This is the code I have thus far:

var str = "<a href=\"https://twitter.com/search?q=fnb\" target=\"_blank\">#fnb</a>, <a href=\"https://twitter.com/search?q=mobilesimcard\" target=\"_blank\">#mobilesimcard</a>, <a href=\"https://twitter.com/search?q=what\" target=\"_blank\">#what</a>, <a href=\"https://twitter.com/search?q=refugeechild\" target=\"_blank\">#refugeechild</a>";



var array = [];

var parts = str.split('target=\"_blank\">', '');



parts.forEach(function (part) {

	var rem1 = part.replace('</a>', '');

	array.push(rem1)

})

var value = array;

console.log(value);

My desired output is: #fnb, #mobilesimcard, #what, #refugeechild

My

str.split()

is not working correctly, and I believe I will have to expand on the

.replace()

as well.

Thank you!

A solution with a regular expression:

var str = "<a href=\"https://twitter.com/search?q=fnb\" target=\"_blank\">#fnb</a>, <a href=\"https://twitter.com/search?q=mobilesimcard\" target=\"_blank\">#mobilesimcard</a>, <a href=\"https://twitter.com/search?q=what\" target=\"_blank\">#what</a>, <a href=\"https://twitter.com/search?q=refugeechild\" target=\"_blank\">#refugeechild</a>";
var array = str.match(/#[a-z-_]+/ig)

console.log(array);

This regex is just a very simple one, there are tons better in the wild, like Best HashTag Regex
