<h2>The <xsl:value-of> Element</h2>
<p>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:</p>
<table width="100%" border="1" class="ex" cellspacing="0">
<tr>
<td>
<pre><?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"></pre>
<pre><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><span class="insert"><xsl:value-of select="catalog/cd/title"/></span></td>
<td><span class="insert"><xsl:value-of select="catalog/cd/artist"/></span></td>
</tr>
</table>
</body>
</html>
</xsl:template></pre>
<pre></xsl:stylesheet></pre>
</td>
</tr>
</table>
<p><b>Note:</b> The value of the <b>select</b> attribute is an XPath
expression.
An XPath expression works like navigating a file system; where a forward slash (/) selects subdirectories.</p>
<p>The result of the transformation above will look like this:</p>
<h2>My CD Collection</h2>
<table border="1">
<tr bgcolor="#9acd32">
<th>Title</th>
<th>Artist</th>
</tr>
<tr>
<td>Empire Burlesque</td>
<td>Bob Dylan</td>
</tr>
</table>
<p><a target="_blank" href="cdcatalog.xml">View the XML file</a>,
<a target="_blank" href="cdcatalog_ex2.xsl">View the XSL file</a>, and
<a target="_blank" href="cdcatalog_with_ex2.xml">View the result</a></p>
<p>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.</p>
<p>In the next chapter you will learn how to use the <b><xsl:for-each></b>
element to loop through the XML elements, and display all of the
records.</p>
