Question

I have some code that gets a web response. How do I take that response and search for a table using its CSS class (class=”data”)? Once I have the table, I need to extract certain field values. For example, in the sample markup below, I need the values of Field #3 and Field #5, so “85” and “1”, respectively.

<table width="570" border="0" cellpadding="1" cellspacing="2" class="data">
  <tr>
    <td width="158"><strong>Field #1:</strong></td>
    <td  width="99">1</td>
    <td  width="119"><strong>Field #2:</strong></td>
    <td  width="176">110</td>
  </tr>
  <tr>
    <td width="158"><strong>Field #3:</strong></td>
    <td  width="99">85</td>
    <td  width="119"><strong>Field #4:</strong></td>
    <td  width="176">-259.34</td>
  </tr>
  <tr>
    <td width="158"><strong>Field #5:</strong></td>
    <td  width="99">1</td>
    <td  width="119"><strong>Field #6:</strong></td>
    <td  width="176">110</td>
  </tr>
  <tr>
    <td width="158"><strong>Field #7:</strong></td>
    <td  width="99">12</td>
    <td  width="119"><strong>Field #8:</strong></td>
    <td  width="176">123.23</td>
  </tr>
</table>

Use the HTML Agility Pack and parse the HTML. If you want to do it the simplest way then go grab its beta (it supports LINQ).
