XSLT Overview

XSL

在学习XSLT之前,我们应当首先理解SL,即EX。

Need for XSL

就超文本文件而言,标签是表、四和跨度等预先定义的;浏览器知道如何为这些文件添加风格,并展示使用中枢式服务的人。但是,在XML文件的情况下,标记没有预先界定。为了理解和模仿XML文件,万维网联合会(W3C)开发了XSL,可作为基于XML的风格表格。一份XSL文件具体规定浏览器应如何提供XML文件。

以下是国际空间法学会的主要部分:

XSLT - 用于将XML文件翻译成其他各类文件。

XPath-用于浏览XML文件。

XSL-FO - 用于编制XML文件。

What is XSLT

XSLT, Extensible Formatsheet Language Transformations, provide the capacity to transformation XML data from one Format to another auto.

How XSLT Works

采用XSLT风格表格确定目标XML文件所适用的转化规则。 XSLT风格表格以XML格式书写。 XSLT处理器采用XSLT风格表格,对目标XML文件适用转化规则,然后以XML、超文本或文本格式生成格式文件。该格式文件随后由异常低价竞标格式使用,以产生实际产出,并将其展示给最终用户。

Advantages

这里是使用异常低价竞标的好处。

独立于方案拟订。变式在一份单独的Xsl文档中书写,再一次是XML文件。

可以通过简单修改Xsl文档中的转变来改变产出。无需修改任何法典。因此,网络设计者可以 style上风格,并能迅速看到产出的变化。

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>
