Filter is a list of HTML code like pattern of regular expressions but it's more simple. It is only using $n to define the data fields. GGRBB read text on HTML source code and compare with text in the filter content to extract necessary field.
Sample source code of filter:
<td class="news-title" nowrap="nowrap"><a href="$1">$2</a></td>
<td class="news-content" nowrap="nowrap">$3</td>
You don't need to learn about how to write the filter source code. This source code will be created automatically when you create new filter by GGRBB control panel. Just enter the remote blog URL and click “Go” button.
