I'm trying to write some code that will check a certain webpage for a metric. Does anyone know of any good tutorials or examples which call on a certain page, and checks for a metric? I would be looking through a table for the current date and checking the impressions metric (see code) This is just the first row but, but I would need to find the current date in the table and find the next "td-impr" class and check what the metric is. I already know how to get the current date in that format, just don't know how to call a page and get to this specific part of the table.
<div id="contentBody" class="flexcroll" style="height: 200px; overflow: hidden;">
<table class="prod">
<tr>
<td class="td-date">05/06/13</td>
<td class="td-impr">0</td>
<td class="td-clicks">0</td>
<td class="td-ctr">0%</td>
</tr>
