从html输入中删除标签sed

我有一个html表格，我想从中删除具有某个类的行。不过：当我尝试sed 's/<tr class="expandable">.*<\/tr>//g只是什么也不做（比如：不删除标记）从html输入中删除标签sed

一个例子输入可以是：

<tr><td>Some col</td></tr> 
<tr class="expandable"> 
    <td colspan="6"> 
     <div class="expandable-content"> 
<p>Holds ACCA Practising Certificate: This indicates a member holding a practising certificate issued by ACCA. This means that the member is authorised to provide a range of general accountancy services to individuals and businesses, including business and tax advice and planning, preparation of personal and business tax returns, set up of book-keeping and business systems, providing book-keeping services, payroll work, assistance with management accounting help with raising finance, budgeting and cash-flow advice, business start-up advice and expert witness.</p> 
     </div> 
    </td> 
</tr>

我不是sed亲和欣赏任何帮助，您可以给我！

我认为有示例输入显示的错字，最后一行可能是''......这可能会工作'perl -0777 -pe's | 。*？ || gs'file'但不像已经指出的那样健壮 – Sundeep

假设你的HTML是有效的XML，你可以像使用xmlstarlet工具：

xmlstarlet ed -d '//tr[@class="expandable"]' <<ENDHTML 
<html><body><table> 
    <tr><td>Some col</td></tr> 
    <tr class="expandable"> 
     <td colspan="6"> 
      <div class="expandable-content"> 
    <p>Holds ACCA Practising Certificate: This indicates a member holding a practising certificate issued by ACCA. This means that the member is authorised to provide a range of general accountancy services to individuals and businesses, including business and tax advice and planning, preparation of personal and business tax returns, set up of book-keeping and business systems, providing book-keeping services, payroll work, assistance with management accounting help with raising finance, budgeting and cash-flow advice, business start-up advice and expert witness.</p> 
      </div> 
     </td> 
    </tr> 
</table></body></html> 
ENDHTML

<?xml version="1.0"?> 
<html> 
    <body> 
    <table> 
     <tr> 
     <td>Some col</td> 
     </tr> 
    </table> 
    </body> 
</html>
