一、XSL(eXtensible Stylesheet Language)扩展样式表语言：主要包含三个部分——XSLT用于XML文档转换，XPath用于在XML文档中导航，XSL-FO用于XML文档格式化。注意：XSL样式表本身也是一个XML文档，所以第一行必须为XML声明。
三、XSLT是一种闭包，它的输入和输出都是树，可以管道化利用，如：文档1 -> 文档2-> 文档3。
四、XSLT语法：XSL样式表由一个或多个模板(template)的规则组成，每个模板含有当前某个指定节点被匹配时所应用的规则。
a) <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">元素
XSLT的根元素，用于定义该文档是一个XSLT样式表，上例中包含版本号以及XSLT命名空间两个属性。其中stylesheet也可写为transform，两者是完全相同的。<xsl:template match="title"> Title </xsl:template>
<xsl:include href="book.xsl"> (:<xsl:import href="book.xsl">:) <xsl:template match="title"> NewTitle </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>
<td><xsl:value-of select="catalog/cd/title"/></td>
<td><xsl:value-of select="catalog/cd/artist"/></td> <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> <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> <xsl:for-each select="catalog/cd">
<xsl:value-of select="title"/>
<xsl:if test="position()!=last()">
<xsl:text>, </xsl:text>
</xsl:if>
<xsl:if test="position()=last()-1">
<xsl:text> and </xsl:text>
</xsl:if>
<xsl:if test="position()=last()">
<xsl:text>!</xsl:text>
</xsl:if>
</xsl:for-each><xsl:choose>
<xsl:when test="expression">
... Output ...
</xsl:when>
<xsl:when test="expression">
... Output ...
</xsl:when>
<xsl:otherwise>
... Output ...
</xsl:otherwise>
</xsl:choose><xsl:variable name="color">
<xsl:choose>
<xsl:when test="@color">
<xsl:value-of select="@color"/>
</xsl:when>
<xsl:otherwise>green</xsl:otherwise>
</xsl:choose>
</xsl:variable><?xml version="1.0" encoding="UTF-8"?> <list> <book ID="666"> <chapter>First Chapter</chapter> <chapter>Second Chapter <chapter>Subchapter 1</chapter> <chapter>Subchapter 2</chapter> </chapter> <chapter>Third Chapter <chapter>Subchapter A</chapter> <chapter>Subchapter B <chapter> subsub a</chapter> <chapter> subsub b</chapter> </chapter> </chapter> </book> </list>
<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions"> <xsl:template match="/"> <xsl:for-each select="//chapter"> <br/> <xsl:number level="multiple" format="1.A.a "/> <xsl:value-of select="./text()"/> </xsl:for-each> </xsl:template> </xsl:stylesheet>
<applet>
<code class="Applet"/>
<codebase>/src/code</codebase>
</applet>
<xsl:template match="/">
<xsl:apply-templates select="applet">
<applet code="{code/@class}" codebase="{codebase}/java"/>
</xsl:apply-templates>
</xsl:stylesheet>
实际效果为：
<applet code="Applet" codebase="src/code/java"/>
五、 XML与XSL关联：
<?xml-stylesheet type="text/xsl" href="***.xslt"?>
<?xml version="1.0" encoding="UTF-8"?> <Name> <AAA repeat="3"/> <BBB repeat="2"/> <CCC repeat="5"/> </Name>
<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions"> <xsl:template match="/Name/*"> <p> <xsl:call-template name="while"> <xsl:with-param name="test"> <xsl:value-of select="@repeat"/> </xsl:with-param> </xsl:call-template> </p> </xsl:template> <xsl:template name="while"> <xsl:param name="test"/> #test记录了repeat的次数 <xsl:value-of select="name()"/> #输出AAA或BBB或CCC <xsl:text/> <xsl:if test="$test!=1"> #判断当前repeat属性是否为1 <xsl:call-template name="while"> <xsl:with-param name="test"> <xsl:value-of select="$test - 1"/> #递归调用while模板，参数修正为test值减1，注意$test和-、-和1之间均有空格 </xsl:with-param> </xsl:call-template> </xsl:if> </xsl:template> </xsl:stylesheet>
CCCCCCCCCCCCCCC
<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions"> <xsl:variable name="totalChapters"> <xsl:value-of select="//chapter[last()]"/> </xsl:variable> <xsl:template match="/"> <xsl:value-of select="$totalChapters"/> </xsl:template> </xsl:stylesheet>
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions">
<xsl:key name="findAuthor" match="list/book" use="author"/>
<xsl:param name="author">Jim Blue</xsl:param>
<xsl:template match="/">
<xsl:copy-of select="key('findAuthor', $author)"/>
</xsl:template>
</xsl:stylesheet><?xml version="1.0" encoding="UTF-8"?> <list> <book ID="234"> <author>Jim Blue</author> <author>Dan Farm</author> <author>Blue Flowers</author> </book> <book ID="666"> <author>Mark Simp</author> <author>Jim Blue</author> <author>Green Trees</author> </book> <book ID="898"> <author>Jay Bart</author> <author>Red Tulips</author> </book> </list>
九、通过XSLT与XQuery生成HTML
给定students.xml文件，按照出生年月日排序，学号为Z00123101的学生信息用绿色显示，学号为Z00123102的学生信息用蓝色显示，其余用红色显示。
如
源students.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<students>
<student id="Z00123101">
<name>The No.1 student</name>
<birthday>1987.2</birthday>
<phone>62220001</phone>
</student>
<student id="Z00123102">
<name>the No.2 student</name>
<birthday>1975.6</birthday>
<phone>62220002</phone>
</student>
<student id="Z00123103">
<name>the No.3 student</name>
<birthday>1978.8</birthday>
<phone>62220003</phone>
</student>
<student id="Z00123104">
<name>the No.4 student</name>
<birthday>1976.2</birthday>
<phone>62220004</phone>
</student>
</students>通过XSLT生成：
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">
<xsl:template match="/">
<html>
<head>
<table border="1" cols="4" width="100%">
<tr>
<th>No</th>
<th>Name</th>
<th>Phone</th>
<th>Birthday</th>
</tr>
<xsl:for-each select="students/student">
<xsl:sort select="birthday"/>
<xsl:choose>
<xsl:when test="@id='Z00123101'">
<tr style="color:green">
<td><xsl:value-of select="@id"/></td>
<xsl:apply-templates select="name|phone"/>
<xsl:apply-templates select="birthday"/>
</tr>
</xsl:when>
<xsl:when test="@id='Z00123102'">
<tr style="color:blue">
<td><xsl:value-of select="@id"/></td>
<xsl:apply-templates select="name|phone"/>
<xsl:apply-templates select="birthday"/>
</tr>
</xsl:when>
<xsl:otherwise>
<tr style="color:red">
<td><xsl:value-of select="@id"/></td>
<xsl:apply-templates select="name|phone"/>
<xsl:apply-templates select="birthday"/>
</tr>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</table>
</head>
<body></body>
</html>
</xsl:template>
<xsl:template match="name|phone|birthday">
<td><xsl:value-of select="."></xsl:value-of></td>
</xsl:template>
</xsl:stylesheet>通过XQuery生成：
xquery version "1.0";
<html>
<head>
<table border="1" cols="4" width="100%">
<tr>
<th>No</th>
<th>Name</th>
<th>Phone</th>
<th>Birthday</th>
</tr>
{
for $x in doc("students.xml")/students/student
order by $x/birthday
return if(data($x/@id)="Z00123102")
then <tr style="color:blue">
<td>{data($x/@id)}</td>
<td>{data($x/name)}</td>
<td>{data($x/phone)}</td>
<td>{data($x/birthday)}</td>
</tr>
else if(data($x/@id)="Z00123101")
then <tr style="color:green">
<td>{data($x/@id)}</td>
<td>{data($x/name)}</td>
<td>{data($x/phone)}</td>
<td>{data($x/birthday)}</td>
</tr>
else <tr style="color:red">
<td>{data($x/@id)}</td>
<td>{data($x/name)}</td>
<td>{data($x/phone)}</td>
<td>{data($x/birthday)}</td>
</tr>
}
</table>
</head>
<body/>
</html>
