为特定单词行添加书签，并在每个书签前添加一行

问：

我有一个列表，如下所示：

  <th class="News">20</th>
  <td class="News"><a href="vector">Vector</a></td>
  <td class="News" style="text-align: right" title="Yesterday: 182">181<img src="/web/20040929104305im_/http://distrowatch.com/images/other/adown.png" alt=">" title="Yesterday: 182"></td>
</tr>
<tr>
  <th class="News">21</th>
  <td class="News"><a href="turbolinux">Turbolinux</a></td>
  <td class="News" style="text-align: right" title="Yesterday: 176">177<img src="/web/20040929104305im_/http://distrowatch.com/images/other/aup.png" alt="<" title="Yesterday: 176"></td>
</tr>
<tr>
  <th class="News">22</th>
  <td class="News"><a href="gnoppix">Gnoppix</a></td>
  <td class="News" style="text-align: right" title="Yesterday: 171">171<img src="/web/20040929104305im_/http://distrowatch.com/images/other/alevel.png" alt="=" title="Yesterday: 171"></td>
</tr>
<tr>
  <th class="News">23</th>
  <td class="News"><a href="aurox">Aurox</a></td>
  <td class="News" style="text-align: right" title="Yesterday: 172">171<img src="/web/20040929104305im_/http://distrowatch.com/images/other/adown.png" alt=">" title="Yesterday: 172"></td>
</tr>
<tr>
  <th class="News">24</th>
  <td class="News"><a href="buffalo">Buffalo</a></td>
  <td class="News" style="text-align: right" title="Yesterday: 163">162<img src="/web/20040929104305im_/http://distrowatch.com/images/other/adown.png" alt=">" title="Yesterday: 163"></td>
</tr>

现在我想通过正则表达式在记事本++中为行添加书签和每个书签行前面的一行添加书签。.png" alt

我尝试使用正则表达式，但没有奏效：

^.+\.png" alt.*\R\K.+
^.+\.png" alt.*$\R(.+)$
^.+\.png" alt.*$\R\K^.+$
^.+\.png" alt.*$\R
^.+\.png" alt.*$\R^.+$

我的问题出在哪里？
