Regex for not matching the specific div

Hello! What is the regex that matches the below text, without matching(ignoring) the class of the div.
<div class="elementor-text-editor elementor-clearfix">?I am using RegexBuddy in Java for testing,so I don’t want that div that have class to be included.So I want to ignore the class.And get only <div> followed by other code below.

<div class="elementor-text-editor elementor-clearfix">
    <h3>Pruduct</h3>
    <p>The description of the product</p>
    <h5>Product data:&nbsp;Product&nbsp;</h5>
    <div>&nbsp;</div>
