XSLT <xsl: for-each> 元素示例
让我们以创建一个<employee>元素表为例，该表的属性为" id"，其子元素为<firstname>，<lastname> <nickname>和<salary>遍历每个员工。
Employee.xml
<?xml version = "1.0"?>
<?xml-stylesheet type = "text/xsl" href = "employee.xsl"?>
<class>
<employee id = "001">
<firstname>Aryan</firstname>
<lastname>Gupta</lastname>
<nickname>Raju</nickname>
<salary>30000</salary>
</employee>
<employee id = "024">
<firstname>Sara</firstname>
<lastname>Khan</lastname>
<nickname>Zoya</nickname>
<salary>25000</salary>
</employee>
<employee id = "056">
<firstname>Peter</firstname>
<lastname>Symon</lastname>
<nickname>John</nickname>
<salary>10000</salary>
</employee>
</class>
Employee.xsl
<?xml version = "1.0" encoding = "UTF-8"?>
<xsl:stylesheet version = "1.0"
xmlns:xsl = "http://www.w3.org/1999/XSL/Transform">
<xsl:template match = "/">
<html>
<body>
<h2>Employee</h2>
<table border = "1">
<tr bgcolor = "pink">
<th>ID</th>
<th>First Name</th>
<th>Last Name</th>
<th>Nick Name</th>
<th>Salary</th>
</tr>
<!--for-each processing instruction
Looks for each element matching the XPath expression
-->
<xsl:for-each select="class/employee">
<tr>
<td>
<!--value-of processing instruction
process the value of the element matching the XPath expression
-->
<xsl:value-of select = "@id"/>
</td>
<td><xsl:value-of select = "firstname"/></td>
<td><xsl:value-of select = "lastname"/></td>
<td><xsl:value-of select = "nickname"/></td>
<td><xsl:value-of select = "salary"/></td>
