位置路徑指定XML文件中節點的位置。路徑可以是絕對路徑或相對路徑。 如果位置路徑以根節點或/
開頭,則它是絕對路徑。 以下是使用絕對路徑定位元素的範例中的一小部分。
/class/student
- 選擇類根節點中的student
節點。<xsl:for-each select = "/class/student">
/class/student/firstname
- 在類根節點中選擇student
節點的名稱。<p><xsl:value-of select = "/class/student/firstname"/></p>
在這個例子中,我們建立了一個範例XML文件students.xml,及其樣式表文件students.xsl,它使用了XPath表示式。
以下是使用的範例XML,檔案: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>
檔案: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>
