Trying to add two numbers but they are wrapped in span tags
<p>I am trying to add two numbers together, but they are dynamically generated in my page and are wrapped in  tags.  Can anyone tell me how I could add these numbers?</p>

<p>This would be an example of two dynamically generated numbers:</p>

<p>The id tags are ALSO dynamically generated.</p>

<pre><code>&lt;span id="thmr_35" class="thmr_call"&gt; 42&lt;/span&gt;
&lt;span id="thmr_42" class="thmr_call"&gt; 11&lt;/span&gt;
</code></pre>

<p>I need to add the two numbers 42 + 11 and then spit out:
Total = 53</p>

<p>Thank you for any help!</p>
