可以檢索元素的注釋。comment() - 獲取屬性name的值。
<xsl:value-of select = "/class/student/preceding-sibling::comment()"/>
示例
在這個例子中，我們創建了一個示例XML文檔students.xml，及其樣式表文檔students.xsl，它使用了XPath運算式。
以下是使用的示例XML，檔：students.xml -
<?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.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>
<h3>Comment(). Xpath expression = "/class/student/preceding-sibling::comment()"</h3>
<xsl:value-of select = "/class/student/preceding-sibling::comment()"/>
<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">
<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:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
在流覽器中打開上面示例代碼檔：student.xml ，得到以下結果 -
