Example study: How to transform XML into XHTML using XSLT.
实例学习:如何通过XSLT把XML转换成XHTML。
The details of this example will be explained in the next chapter.
此实例的详细情况将在下一章中作详细说明。
The root element that declares the document to be an XSL style sheet is <xsl:stylesheet> or <xsl:transform>.
我们使用根元素<xsl:stylesheet> 或<xsl:transform>对XSL样式表文档进行声明。
Note: <xsl:stylesheet> and <xsl:transform> are completely synonymous and either can be used!
注意: <xsl:stylesheet> 和<xsl:transform>是完全相同的,使用哪一个都可以。
The correct way to declare an XSL style sheet according to the W3C XSLT Recommendation is:
根据W3C XSLT 的推荐标准,声明 XSL 样式表的正确方法如下:
<xsl:stylesheet version="1.0" |
or:
或:
<xsl:transform version="1.0" |
To get access to the XSLT elements, attributes and features we must declare the XSLT namespace at the top of the document.
如果希望访问XSLT元素、属性和特征,那么,我们必须在文件的头部事先声明XSLT命名空间。
The xmlns:xsl="http://www.w3.org/1999/XSL/Transform" points to the official W3C XSLT namespace. If you use this namespace, you must also include the attribute version="1.0".
“xmlns:xsl="http://www.w3.org/1999/XSL/Transform” 指出了官方的W3C XSLT 命名空间。如果你使用了这个命名空间,你也必须注明属性版本“version="1.0"。
We want to transform the following XML document ("cdcatalog.xml") into XHTML:
让我们把下面的XML文档("cdcatalog.xml")转换成XHTML吧:
<?xml version="1.0" encoding="ISO-8859-1"?> |
Viewing XML Files in Firefox and Internet Explorer: Open the XML file (typically by clicking on a link) - The XML document will be displayed with color-coded root and child elements. A plus (+) or minus sign (-) to the left of the elements can be clicked to expand or collapse the element structure. To view the raw XML source (without the + and - signs), select "View Page Source" or "View Source" from the browser menu.
在火狐和IE浏览器中查看XML文件的方法: 打开XML文件(通常情况下是通过链接打开的)—XML文件将会显示包含颜色代码的根元素和子元素。单击左边元素的“+”和“-”,就可以展开或者收回元 素结构列表。查看XML源文件的源代码(不含加号+和减号-),在浏览器菜单里选择“查看—源文件[ IE ]”或者“查看—页面源代码[ FF ]”。
Viewing XML Files in Netscape 6: Open the XML file, then right-click in XML file and select "View Page Source". The XML document will then be displayed with color-coded root and child elements.
在Netscape 6中查看XML文件的方法:打开XML文件,在XML文件里右键单击选择“查看—页面源代码”。XML文件将会把标有颜色代码的根元素和子元素的文档显示出来。
Viewing XML Files in Opera 7: Open the XML file, then right-click in XML file and select "Frame" / "View Source". The XML document will be displayed as plain text.
在Opera 7中查看XML文件的方法: 打开XML文件,在XML文件里右键单击选择“框架/查看源代码”。XML文件将会以纯文本的形式显示。
View "cdcatalog.xml"
查看 "cdcatalog.xml"
Then you create an XSL Style Sheet ("cdcatalog.xsl") with a transformation template:
此时,你已经通过一个转换模板创建了一个XSL样式表文档("cdcatalog.xsl")。
<?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" <xsl:template match="/"> </xsl:stylesheet> |
View "cdcatalog.xsl"
查看"cdcatalog.xsl"
Add the XSL style sheet reference to your XML document ("cdcatalog.xml"):
把XSL样式表参数添加到XML文件("cdcatalog.xml")中:
<?xml version="1.0" encoding="ISO-8859-1"?> |
If you have an XSLT compliant browser it will nicely transform your XML into XHTML.
如果你有一个支持XSLT的浏览器,它将会准确地帮你把XML文件转换成XHTML。
