XSLT 实例
<xsl:template> 元素
<xsl:template> 元素用于构建模板。
match 属性用于关联 XML 元素和模板。match 属性也可用来为整个文档定义模板。match 属性的值是 XPath 表达式（举例，match="/" 定义整个文档）。
<?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <html> <body> <h2>My CD Collection</h2> <table border="1"> <tr bgcolor="#9acd32"> <th>Title</th> <th>Artist</th> </tr> <tr> <td>.</td> <td>.</td> </tr> </table> </body> </html> </xsl:template> </xsl:stylesheet>
cdcatalog.xml：
<?xml version="1.0" encoding="ISO-8859-1"?> <?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?> <catalog> <cd> <title>Empire Burlesque</title> <artist>Bob Dylan</artist> <country>USA</country> <company>Columbia</company> <price>10.90</price> <year>1985</year> </cd> </catalog>
IE里运行：
<xsl:value-of> 元素
<xsl:value-of> 元素用于提取某个选定节点的值，并把值添加到转换的输出流中：
<?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <html> <body> <h2>My CD Collection</h2> <table border="1"> <tr bgcolor="#9acd32"> <th>Title</th> <th>Artist</th> </tr> <tr> <td> <xsl:value-of select="catalog/cd/title" /> </td> <td> <xsl:value-of select="catalog/cd/artist" /> </td> </tr> </table> </body> </html> </xsl:template> </xsl:stylesheet>
<?xml version="1.0" encoding="ISO-8859-1"?> <?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?> <catalog> <cd> <title>Empire Burlesque</title> <artist>Bob Dylan</artist> <country>USA</country> <company>Columbia</company> <price>10.90</price> <year>1985</year> </cd> </catalog>
select 属性的值是一个 XPath 表达式。此表达式的工作方式类似于定位某个文件系统，在其中正斜杠可选择子目录。
<xsl:for-each> 元素
<xsl:for-each> 元素可用于选取指定的节点集中的每个 XML 元素。
<?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <html> <body> <h2>My CD Collection</h2> <table border="1"> <tr bgcolor="#9acd32"> <th>Title</th> <th>Artist</th> </tr> <xsl:for-each select="catalog/cd"> <tr> <td> <xsl:value-of select="title" /> </td> <td> <xsl:value-of select="artist" /> </td> </tr> </xsl:for-each> </table> </body> </html> </xsl:template> </xsl:stylesheet>
<?xml version="1.0" encoding="ISO-8859-1"?> <?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?> <catalog> <cd> <title>Empire Burlesque1</title> <artist>Bob Dylan2</artist> <country>USA</country> <company>Columbia</company> <price>10.90</price> <year>1985</year> </cd> <cd> <title>Empire Burlesque2</title> <artist>Bob Dylan1</artist> <country>USA</country> <company>Columbia</company> <price>10.90</price> <year>1985</year> </cd> </catalog>
<xsl:sort> 元素用于对结果进行排序
<?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <html> <body> <h2>My CD Collection</h2> <table border="1"> <tr bgcolor="#9acd32"> <th>Title</th> <th>Artist</th> </tr> <xsl:for-each select="catalog/cd"> <xsl:sort select="artist" /> <tr> <td> <xsl:value-of select="title" /> </td> <td> <xsl:value-of select="artist" /> </td> </tr> </xsl:for-each> </table> </body> </html> </xsl:template> </xsl:stylesheet>
<?xml version="1.0" encoding="ISO-8859-1"?> <?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?> <catalog> <cd> <title>Empire Burlesque1</title> <artist>Bob Dylan3</artist> <country>USA</country> <company>Columbia</company> <price>10.90</price> <year>1985</year> </cd> <cd> <title>Empire Burlesque3</title> <artist>Bob Dylan2</artist> <country>USA</country> <company>Columbia</company> <price>10.90</price> <year>1985</year> </cd> <cd> <title>Empire Burlesque2</title> <artist>Bob Dylan1</artist> <country>USA</country> <company>Columbia</company> <price>10.90</price> <year>1985</year> </cd> </catalog>
<xsl:if> 元素
如需放置针对 XML 文件内容的条件测试，请向 XSL 文档添加 <xsl:if> 元素。
<?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <html> <body> <h2>My CD Collection</h2> <table border="1"> <tr bgcolor="#9acd32"> <th>Title</th> <th>Artist</th> </tr> <xsl:for-each select="catalog/cd"> <xsl:if test="price > 10"> <tr> <td> <xsl:value-of select="title" /> </td> <td> <xsl:value-of select="artist" /> </td> </tr> </xsl:if> </xsl:for-each> </table> </body> </html> </xsl:template> </xsl:stylesheet>
<?xml version="1.0" encoding="ISO-8859-1"?> <?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?> <catalog> <cd> <title>Empire Burlesque1</title> <artist>Bob Dylan3</artist> <country>USA</country> <company>Columbia</company> <price>10.90</price> <year>1985</year> </cd> <cd> <title>Empire Burlesque3</title> <artist>Bob Dylan2</artist> <country>USA</country> <company>Columbia</company> <price>9.90</price> <year>1985</year> </cd> <cd> <title>Empire Burlesque2</title> <artist>Bob Dylan1</artist> <country>USA</country> <company>Columbia</company> <price>11.90</price> <year>1985</year> </cd> </catalog>
<xsl:choose> 元素
<xsl:choose> 元素用于结合 <xsl:when> 和 <xsl:otherwise> 来表达多重条件测试。
<?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <html> <body> <h2>My CD Collection</h2> <table border="1"> <tr bgcolor="#9acd32"> <th>Title</th> <th>Artist</th> </tr> <xsl:for-each select="catalog/cd"> <tr> <td> <xsl:value-of select="title" /> </td> <xsl:choose> <xsl:when test="price > 10"> <td bgcolor="#ff00ff"> <xsl:value-of select="artist" /> </td> </xsl:when> <xsl:when test="price > 9"> <td bgcolor="#cccccc"> <xsl:value-of select="artist" /> </td> </xsl:when> <xsl:otherwise> <td> <xsl:value-of select="artist" /> </td> </xsl:otherwise> </xsl:choose> </tr> </xsl:for-each> </table> </body> </html> </xsl:template> </xsl:stylesheet>
<?xml version="1.0" encoding="ISO-8859-1"?> <?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?> <catalog> <cd> <title>Empire Burlesque1</title> <artist>Bob Dylan3</artist> <country>USA</country> <company>Columbia</company> <price>10.90</price> <year>1985</year> </cd> <cd> <title>Empire Burlesque3</title> <artist>Bob Dylan2</artist> <country>USA</country> <company>Columbia</company> <price>9.90</price> <year>1985</year> </cd> <cd> <title>Empire Burlesque2</title> <artist>Bob Dylan1</artist> <country>USA</country> <company>Columbia</company> <price>11.90</price> <year>1985</year> </cd> </catalog>
<xsl:apply-templates> 元素
<xsl:apply-templates> 元素可把一个模板应用于当前的元素或者当前元素的子节点。
假如我们向 <xsl:apply-templates> 元素添加一个 select 属性，此元素就会仅仅处理与属性值匹配的子元素。我们可以使用 select 属性来规定子节点被处理的顺序。
<?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <html> <body> <h2>My CD Collection</h2> <xsl:apply-templates /> </body> </html> </xsl:template> <xsl:template match="cd"> <p> <xsl:apply-templates select="title" /> <xsl:apply-templates select="artist" /> </p> </xsl:template> <xsl:template match="title"> Title: <span style="color:#ff0000"> <xsl:value-of select="." /> </span> <br /> </xsl:template> <xsl:template match="artist"> Artist: <span style="color:#00ff00"> <xsl:value-of select="." /> </span> <br /> </xsl:template> </xsl:stylesheet>
<?xml version="1.0" encoding="ISO-8859-1"?> <?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?> <catalog> <cd> <title>Empire Burlesque1</title> <artist>Bob Dylan3</artist> <country>USA</country> <company>Columbia</company> <price>10.90</price> <year>1985</year> </cd> <cd> <title>Empire Burlesque3</title> <artist>Bob Dylan2</artist> <country>USA</country> <company>Columbia</company> <price>9.90</price> <year>1985</year> </cd> <cd> <title>Empire Burlesque2</title> <artist>Bob Dylan1</artist> <country>USA</country> <company>Columbia</company> <price>11.90</price> <year>1985</year> </cd> </catalog>
