您应该能够通过他们抓取这样：

<?php 
    $simpleHTMLDom = new simple_html_dom(); 
    $simpleHTMLDom->load($html); 
    $tableRows = $simpleHTMLDom->find('tr'); 

    $rows = array(); 
    if (!empty($tableRows)) { 
     foreach ($tableRows as $tableRow) { 
      $row = array(); 
      $tableColumns = $tableRow->find('td.avg, td.percent'); 
      if (!empty($tableColumns)) { 
       foreach ($tableColumns as $tableColumn) { 
        $row[$tableColumn->class] = $tableColumn->innertext; 
       } 
      } 
      $rows[] = $row; 
     } 
    } 
    print_r($rows); 
?>
