Is it possible to read data from a table on a site, store that data into a txt file, each time the script is run, compare the same table, if it is different update the txt file?

The table data needed will be in the format of
Html:
 <td class="col_status"> <span class="ht"><strong>THIS_DATA</strong></span> <span class="score"><strong>THIS_DATA</strong>THIS_DATA</span> <span class="at">THIS_DATA</span> </td> <td class="col_comment">THIS_DATA</td>
