编写xhtml代码出现错误：

This XML file does not appear to have any style information associated with it. The document tree is shown below.

    <div>This is <cite>a citation</cite> in a division.</div>

    <div>This is <var>a variable name</var> in a division.</div>
    <div><quot>This is a quot</quot></div>
  </body>
</html>

找了半天，终于找到了，因为 <html xmlns = "http://www.w3.org/1999/en" lang= "en" xml:lang = "en">，这句错了，改为：

改正后的代码如下：

<?xml version = "1.0" encoding ="UTF-8"?>
<!DOCTYPE html PUBLIC
	  "-//W3C//DTD XHTML 1.0 Transitional//EN"
	  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns = "http://www.w3.org/1999/xhtml" lang= "en" xml:lang = "en">
  <head>
    <title>First xhtml document</title>
    </head>
  <body>
    <div>This is <abbr title = "www.anacronym.com">an acronym</abbr> in a division.</div>
    <div>This is <cite>a citation</cite> in a division.</div>
    <div>This is <code>some code</code> in a division.</div>
    <div>This is <em>EMPHASIZED TEXT</em> in a division.</div>
    <div>This is <q>a quotation</q> in a division.</div>
    <div>This is <samp>a sample</samp> in a division.</div>
    <div>This is <span>a span </span> in a division.</div>
    <div>This is <strong>strong text</strong> in a division.</div>
    <div>This is <var>a variable name</var> in a division.</div>
    <div><quot>This is a quot</quot></div>
  </body>
</html>

运行结果如下：

This is a citation in a division.
This is some code in a division.
This is EMPHASIZED TEXT in a division.
This is a quotation in a division.
This is a sample in a division.
