XHTML 严格 1.0 .无限错误

我已经检查了我的XHTML严格1.0代码，我遇到了很多错误验证器：validator.w3.org 请您帮助我修复错误

法典：

      Documenting my trip around the US on my
very own Segway

    <p>
      Well I made it 1200 miles already, and I passed
       through some interesting places on the way:
   </p>
   <ol> <!-- ordered list -->
<li>Walla Walla, WA</li>
<li>Magic City, ID</li>
<li>Bountiful, UT</li>
<li>Last Chance, CO</li>
<li>Why, AZ</li>
<li>Truth or Consequences, NM</li>
    </ol>
    <h2> July 14, 2005 </h2>
    <p>
      I saw some Burma Shave style signs on the side of the
       road today :
    </p>
    <blockquote>
Passing cars,
When you can't see, May get you,
A glimpse,
Of eternity.
    </blockquote>
    <p>
      I definitely won't be passing any cars.
    </p>
    <h2> June 2, 2005 </h2>
    <img src="images/segway1.jpg"/ alt="segway">
    <p>
      My frst day of the trip! I can't believe I fnally got
       everything packed and ready to go. Because I'm on a Segway,
       I wasn't able to bring a whole lot with me: cellphone, iPod,
       digital camera, and a protein bar. Just the essentials. As
       Lao Tzu would have said, <q>A journey of a thousand miles begins
       with one Segway</q>

谢谢大家

不要先使用验证器（先使用 XML 解析器），也不要使用旧版本的 XHTML。您应该将HTML5用于HTML和XHTML用于XML解析器，这将立即捕获大约80%的渲染错误并简化您的开发。所以这意味着使用XHTML5可以两全其美。要使用HTML5，您需要使用HTML5元素。要使用 XML 解析器，您需要将页面作为application/xhtml+xml提供。在本地，您需要保存扩展名为.xhtml的文件。不要让对XHTML的压倒性消极态度破坏XML解析器的有用性，最好的使用最好的工具，当他们犯错时忽略大众。只要你把它与HTML5结合使用，那么你就会做你能做的最多的事情，这使你远远领先于大多数人。

对于服务器，您需要进行内容协商。当你到达PHP时，在发送非头数据（例如任何HTML/echo）之前使用以下方法：

if (stristr($_SERVER['HTTP_ACCEPT'],'application/xhtml+xml'))
{
 header('Content-Type: application/xhtml+xml');
}

在你达到这一点之前，使用像WinMerge这样的程序来确定整个页面的代码有何不同，直到你能够缩小它的范围。
