Question

characters occurs like A, B, C and .... are variables and count is not fixed

How to identifies how many variables are there and stored in an array

Answer 1

Use regex to find all your matches. Using a while loop you can iterate through multiple matches and push them in an array. Try this.

var String = "/city=<A>/state=<B>/sub_div=<C>/type=pos/div=<D>/cli_name=Cstate<E>/<F>/<G>";
var myRegexp = /\<.\>/gm;
var matches = [];
var match = myRegexp.exec(String);

while (match != null) {  
  matches.push(match[0])
  match = myRegexp.exec(String);
}

console.log(matches)

Answer 2

Please review below code that will help to resolve your issue. It may find any non word characters and create a non-word array.

 let str = "/city=<A>/state=<B>/sub_div=<C>/type=pos/div=<D>/cli_name=Cstate<E>/<F>/<G>"; let arrStr = str.split(""); var strRegExp = /\\W/g; let arrNonWord = []; arrStr.forEach(function(str){ var result = str.match(strRegExp); if(result) arrNonWord.push(result[0]); }); console.log(arrNonWord);
