<xsl:template> <xsl:for-each>

The <xsl:value-of> element is used to extract the value of a selected node.
<xsl:value-of>元素用于选取选择节点值。

The <xsl:value-of> Element
<xsl:value-of>元素

The <xsl:value-of> element can be used to extract the value of an XML element and add it to the output stream of the transformation:
<xsl:value-of>元素可以用来选取XML元素以及把它添加到已被转换的输出流里中去。

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">

 <html>
 <body>
   <h2>My CD Collection</h2>
   <table border="1">
     <tr bgcolor="#9acd32">

       <th>Title</th>
       <th>Artist</th>
     </tr>
     <tr>
      <td><xsl:value-of select="catalog/cd/title"/></td>

      <td><xsl:value-of select="catalog/cd/artist"/></td>
     </tr>
   </table>
 </body>
 </html>

</xsl:template>
</xsl:stylesheet>

Note: The value of the select attribute is an XPath expression. An XPath expression works like navigating a file system; where a forward slash (/) selects subdirectories.
注意: 选择（select）属性值是一个XPath表达式。XPath表达式的作用类似于对文件系统进行操作，通过在其前段添加“/”来选择子目录。

The result of the transformation above will look like this:
通过上面运行的代码，转换结果如下：

My CD Collection
我的CD集

Title Artist
Empire Burlesque Bob Dylan

View the XML file, View the XSL file, and View the result
XML 文件, XSL 文件, 以及 结果页面

The result from this example was also a little disappointing, because only one line of data was copied from the XML document to the output.
通过这个例子得到的结果同样让人有点失望，因为只有一行数据从XML文件中复制到结果。

In the next chapter you will learn how to use the <xsl:for-each> element to loop through the XML elements, and display all of the records.
在下一章中，你将会学到通过XML元素如何使用<xsl:for-each>元素来做循环以及显示所有的记录。
