How can I select ONLY text input elements?

I'm stacking how I should select text input elements. Is there any way to select "type" property or something?

index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>JavaScript and the DOM</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <section>
            <h1>Making a Webpage Interactive</h1>
            <p>JavaScript is an exciting language that you can use to power web servers, create desktop programs, and even control robots. But JavaScript got its start in the browser way back in 1995.</p>

            <ul>
                <li>Item One: <input type="text"></li>
                <li>Item Two: <input type="text"></li>
                <li>Item Three: <input type="text"></li>
                <li>Item Four: <input type="text"></li>
            </ul>
            <button>Save</button>
        </section>
        <script src="app.js"></script>
    </body>
</html>
app.js 
let section = document.getElementsByTagName('section')[0];

section.addEventListener('click', (e) => {
  if(e.target.tagName === "LI"){
  e.target.style.backgroundColor = 'rgb(255, 255, 0)';
  }
});

You can select only the "input" elements by passing it as a parameter to the selector: document.getElementsByTagName("INPUT")

You can select by type using the querySelectorAll() method:

document.querySelectorAll('input[type=text]');
