Incorrect Rank Parsing

When the Rank, either Overall and/or Yesterday, remains the same as the previous day, no arrow up or down graphic is displayed. This creates a problem for the current regex. Here are three examples of the HTML code with this problem:

Both Overall and Yesterday neither increment or decrement

<tr>
     <td align="left" class="phead2">Rank:</td>
     <td align="right">
        6     </td>
     <td align="right">
        1     </td>
</tr>

Only Overall doesn't increment or decrement

<tr>
     <td align="left" class="phead2">Rank:</td>
     <td align="right">
        3     </td>
     <td align="right">
        60<span style="color: #009900">(<img src="/images/up.gif" alt="+">10)</span>     </td>
</tr>

Only Yesterday doesn't increment or decrement

<tr>
     <td align="left" class="phead2">Rank:</td>
     <td align="right">
        1772<span style="color: #009900">(<img src="/images/up.gif" alt="+">3)</span>     </td>
     <td align="right">
        343     </td>
</tr>

Baseline, where both Overall and Yesterday rank have a graphic

<tr>
     <td align="left" class="phead2">Rank:</td>
     <td align="right">
        15706<span style="color: #009900">(<img src="/images/up.gif" alt="+">11)</span>     </td>
     <td align="right">
        999<span style="color: #009900">(<img src="/images/up.gif" alt="+">67)</span>     </td>
</tr>
