How to remove all attributes from html?

Question

I have raw html with some css classes inside for various tags.

Example:

Input:

<p class="opener" itemprop="description">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Neque molestias natus iste labore a accusamus dolorum vel.</p>

and I would like to get just plain html like:

Output:

<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Neque molestias natus iste labore a accusamus dolorum vel.</p>

I do not know names of these classes. I need to do this in JavaScript (node.js).

Any idea?

This can be done with Cheerio, as I noted in the comments.
To remove all attributes on all elements, you'd do:

var html = '<p class="opener" itemprop="description">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Neque molestias natus iste labore a accusamus dolorum vel.</p>';

var $ = cheerio.load(html);   // load the HTML

$('*').each(function() {      // iterate over all elements
    this.attribs = {};     // remove all attributes
});

var html = $.html();          // get the HTML back
