Insert an element before and after substring
<p>How would you insert substrings between  elements using regular expressions or an alternative form in javascript/jQuery?</p>

<p>For example I have the following string:</p>

<blockquote>
  <p><code>This is a string 015 with numbers 1486453 randomly 10 inserted
  between words 0954</code></p>
</blockquote>

<p>If my regex is to find all numbers, the result would be the following:</p>

<blockquote>
  <p><code>This is a string &lt;span&gt;015&lt;/span&gt; with numbers &lt;span&gt;1486453&lt;/span&gt;
  randomly &lt;span&gt;10&lt;/span&gt; inserted between words &lt;span&gt;0954&lt;/span&gt;</code></p>
</blockquote>
