XSLT Syntax

让我们看看一下XML档案的样本,即学生Xml,必须将其转化为一份精心设计的超文本文件。

students.xml

<?xml version = "1.0"?>
<class> 
   <student rollno = "393">
      <firstname>Dinkar</firstname> 
      <lastname>Kad</lastname> 
      <nickname>Dinkar</nickname> 
      <marks>85</marks>
   </student> 
   <student rollno = "493"> 
      <firstname>Vaneet</firstname> 
      <lastname>Gupta</lastname> 
      <nickname>Vinni</nickname> 
      <marks>95</marks>
   </student> 
   <student rollno = "593"> 
      <firstname>Jasvir</firstname> 
      <lastname>Singh</lastname> 
      <nickname>Jazz</nickname> 
      <marks>90</marks> 
   </student> 
</class>

我们需要为上述XML文件确定XSLT风格文件,以达到以下标准:

页: 1

专栏应当有以下负责人: 页: 1

表必须载有学生的详细情况。

Step 1: Create XSLT document

制作XSLT文件,以满足上述要求,将其命名为学生,并在学生所在的同一地点保存。

students.xsl

<?xml version = "1.0" encoding = "UTF-8"?>
<!-- xsl stylesheet declaration with xsl namespace: 
Namespace tells the xlst processor about which 
element is to be processed and which is used for output purpose only 
--> 
<xsl:stylesheet version = "1.0" 
xmlns:xsl = "http://www.w3.org/1999/XSL/Transform">   
<!-- xsl template declaration:  
template tells the xlst processor about the section of xml 
document which is to be formatted. It takes an XPath expression. 
In our case, it is matching document root element and will 
tell processor to process the entire document with this template. 
--> 
   <xsl:template match = "/"> 
      <!-- HTML tags 
         Used for formatting purpose. Processor will skip them and browser 
            will simply render them. 
      --> 
		
      <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> 
				
               <!-- for-each processing instruction 
               Looks for each element matching the XPath expression 
               --> 
				
               <xsl:for-each select="class/student"> 
                  <tr> 
                     <td> 
                        <!-- value-of processing instruction 
                        process the value of the element matching the XPath expression 
                        --> 
                        <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>

Step 2: Link the XSLT Document to the XML Document

更新学生Xxml文件,附有以下Xml式表格。 3. 给学生带来微薄的价值。

<?xml version = "1.0"?> 
<?xml-stylesheet type = "text/xsl" href = "students.xsl"?> 
<class> 
... 
</class>

Step 3: View the XML Document in Internet Explorer

students.xml

<?xml version = "1.0"?>
<?xml-stylesheet type = "text/xsl" href = "students.xsl"?> 
<class> 
   <student rollno = "393"> 
      <firstname>Dinkar</firstname> 
      <lastname>Kad</lastname> 
      <nickname>Dinkar</nickname> 
      <marks>85</marks> 
   </student> 
   <student rollno = "493"> 
      <firstname>Vaneet</firstname> 
      <lastname>Gupta</lastname> 
      <nickname>Vinni</nickname> 
      <marks>95</marks> 
   </student> 
   <student rollno = "593"> 
      <firstname>Jasvir</firstname> 
      <lastname>Singh</lastname> 
      <nickname>Jazz</nickname> 
      <marks>90</marks> 
   </student> 
</class>
