Replace numbers in String Javascript

const dataString = JSON.stringify(dataArray);    
const regex = /<span.*?>|<\/span>/gm;
const newData = dataString.replace(regex,'');

JSON.parse(newData);

This should do it.

You can iterate the array and replace the content inner the arrow. Like that:

arr = [
    {
        "name": "testOne",
        "tag": "<span id=my-test-1>Test One</span>"
    },
    {
        "name": "testTwo",
        "tag": "Test Two"
    },
    {
        "name": "testThree",
        "tag": "Test Three"
    },
    {
        "name": "testFour",
        "tag": "<span id=my-test-2>Test Four</span>"
    }
]



n = arr.map(a => {
  a.tag = a.tag.replace(/>.*</g, "><");
  return a;
})

console.log(n)

you can do it using regex

const dataToString = JSON.stringify(dataArray);    
const regex = /"<span([^]*)</span>"/gm;
const newData = dataString.replace(regex,"");

JSON.parse(newData);

when I put this code ([^]*) between the span tags it matches any character
