示例
此示例通過迭代每個學生創建一個<student>元素的表，<student>元素屬性為rollno，其子元素(或節點)- <firstname>，<lastname>， <nickname>和<marks>。 它檢查分數(mark)大於90，然後列印學生的詳細資訊。
檔：students.xml 的內容如下 -
<?xml version = "1.0"?>
<?xml-stylesheet type = "text/xsl" href = "students.xsl"?>
<class>
<student rollno = "393">
<firstname>Dinkar</firstname>
<lastname>Su</lastname>
<nickname>MaXX</nickname>
<marks>88</marks>
</student>
<student rollno = "493">
<firstname>Vaneet</firstname>
<lastname>Lee</lastname>
<nickname>Vicky</nickname>
<marks>95</marks>
</student>
<student rollno = "593">
<firstname>Jasvir</firstname>
<lastname>Wong</lastname>
<nickname>Jazz</nickname>
<marks>90</marks>
</student>
</class>
檔：students.sxl 的內容如下 -
<?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>Students</h2>
<table border = "1">
<tr bgcolor = "#9acd32">
<th>Roll No</th>
<th>First Name</th>
<th>Last Name</th>
<th>Nick Name</th>
<th>Marks</th>
</tr>
<xsl:for-each select = "class/student">
<xsl:if test = "marks > 90">
<tr>
<td><xsl:value-of select = "@rollno"/></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 = "marks"/></td>
</tr>
</xsl:if>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
