<xsl:value-of> 元素
<xsl:value-of> 元素用于提取某个选定节点的值，并把值添加到转换的输出流中：
<?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:select The value of the attribute is an XPath expression. This expression works in a way similar to locating a file system, where the forward slash can be used to select subdirectories.
The above transformation result is similar to this:
View this XML file,View this XSL file,And view the result.
The result of this example has a little flaw: only one line of data from the XML document is copied to the output result.
In the following chapters, you will learn how to use <xsl:for-each> The element is used to iterate over XML elements and display all records.
