title: Find and replace text with jquery, only text no child elements
body: <p>I want to find and replace text with jquery. I want to change "SKU:" to "art nu."</p>
  
  <pre><code>&lt;span itemprop="productID" class="sku_wrapper"&gt;
     SKU: 
     &lt;span class="sku"&gt;
        5-144
     &lt;/span&gt;.
  &lt;/span&gt;
  </code></pre>
  
  <p>I tried:</p>
  
  <pre><code>$(".product_meta&gt;.sku_wrapper:contains('SKU:')" ).text('art nu.');
  </code></pre>
  
  <p>but this delete the child span sku.</p>
  
  <p>Hope someone has a solution...</p>
