title: Wordpress get taxonomy name with slug
body: <p>How can I get a taxonomy id or name with only the taxonomy slug ?</p>
  
  <p>I guess I'm looking for the equivalent of <code>get_term_by()</code> but for taxonomies. </p>
  
  <p>Edit : I must specify that I'm trying to get the tax ID of a WooCommerce product attribute.</p>
  
  <p>Thanks</p>
