Substitute the text within a personalized tag with the provided content

Need help with a dynamic string

<li>&emsp;Content Test 1</li>
.

Looking for regEx solution to replace tags so the final output is

<ul><li>Content Test 1</li></ul>

(Removing &emsp and adding <ul> while preserving inner content)

Existing solutions work for static content, but I'm dealing with user-generated input.

Thanks in advance!

Answer №1

It is advised to avoid using RegExp when you have access to a DOM or a DOM Parser.

const string = `<li>&emsp;Content Test 1</li>`;
const ul = document.createElement('ul');
ul.innerHTML = string;
ul.firstElementChild.textContent = ul.firstElementChild.textContent.trim();
console.log(ul.outerHTML)

Answer №2

Another way to add tags is by using

<li>&emsp;Content Test 1</li>
in this format:
{ul}<li>Content Test 1</li>{ulc}

You can then utilize the .replace() function as follows:

string.replace(/{ul}/g, "<ul>");
string.replace(/{ulc}/g, "</ul>");

The / __ /g specifies that the replace() function should replace all instances of the specified content instead of just the first one.
