title: How to filter table rows based on a not displayed attribute into span
body: <p>I have a table where each row is an address. Each row has, as well, a zip code but it's hidden.
  I need a textbox to filter the address rows <strong>that matches with the zip entered</strong>. The field to search is named as "zip".</p>
  
  <p>Here's my table:</p>
  
  <pre><code>&lt;asp:DataList
    id="list1"
    runat="server"&gt;
    &lt;ItemTemplate&gt;
       &lt;cc1:SWCLabel 
           runat="server"
           Text ='&lt;%# Eval("address")%&gt;'
           zip='&lt;%# Eval("zip")%&gt;'
            /&gt;
    &lt;/ItemTemplate&gt;
  </code></pre>
  
  <p></p>
  
  <p>Each table rows is rendered like this, note the zip attribute into the span:</p>
  
  <pre><code> &lt;tr&gt;
    &lt;td&gt;
        &lt;span zip="11"&gt;address mmomo&lt;/span&gt;
    &lt;/td&gt;
      &lt;/tr&gt;
  </code></pre>
  
  <p><strong>UPDATED DEMO:</strong>
  Here's the demo: The zip textbox matches the zip entirely but I need that matches zips that contains or starts with the text entered:
