注意XSLT不能对输入文档的DOM树进行更改
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

 1 循环 for-each
 xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output method="text" indent="no"/>

 <xsl:template match="a">
 <xsl:for-each select="./node()">
 <xsl:choose>
 
 <xsl:when test="./self::text()">StartATag<xsl:copy select="."/>EndATag</xsl:when>

 
 <xsl:when test="./self::*">StartBTag<xsl:copy-of select="./node()"/>EndBTag</xsl:when>
 </xsl:choose>
 </xsl:for-each>
 </xsl:template>

 </xsl:stylesheet>

==================================================================

 2 div 定义元素与属性

 <xsl:element name="div">
 <xsl:attribute name="type"><xsl:text>maintitle</xsl:text></xsl:attribute>
 <xsl:attribute name="name"><xsl:value-of select="./PAM_Attributes/PAM_Attr[@name='tqID']/@value"/></xsl:attribute>
 <xsl:attribute name="class"><xsl:text>maintitle</xsl:text></xsl:attribute>
 <xsl:copy-of select="./PAM_Attributes/following-sibling::*"/>
 </xsl:element>

==================================================================

 3 在XSLT中操作多个XML文件
 <xsl:variable name="docs1" select="document('./file1.XML')"/>
 <xsl:copy-of select="$docs1"/>

 <xsl:variable name="docs2" select="document('./file2.XML')"/>
 <xsl:copy-of select="$docs2"/>

==================================================================

 4 无穷递归错误提示
 The XSL processor stack has overflowed - probable cause is
 infinite template recursion.

==================================================================

 5 变量算术操作示例
 <xsl:value-of select="$nsLength*10"/>

==================================================================

 6 xslt模板参数 param 　
 <?xml version="1.0" encoding="UTF-8" ?>
 　　<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
 　　<xsl:param name="Key1"/>
 　　<xsl:param name="Path"/>

==================================================================
 7 Makefile for xsltproc
 # For XSLT
 PARSE = xsltproc
 SRC = main1.xml
 STYLESHEET = ../../xsl/makepaper.xsl
 OUTPUT = ../../output.html


 all : $(SRC) $(STYLE)
 $(PARSE) $(STYLESHEET) $(SRC) > $(OUTPUT)

 clean:
 del $(OUTPUT)

 8 libxslt库辅助工具xlstproc 用法示例
 带参数的xslt para xslt
 WURFL XSLT Tools
 by Roland Guelle

 The WURFL information is stored in XML. So the simpliest way to manipulate and transformm WURLF is XSLT.
 If you have ideas or own XSLT, your help is welcome :)

 These stylesheets are tested with xsltproc from the package libxslt. I only use this on the command line, if you need a GUI - there are lot of tools that helps you working with XSLT.
 Some exslt extensions are used, so please check if your XSLT processor supports this.

 If you have never worked with a XSLT processor or the command line before, add to WURFL and open the file with Firefox.

 Available XSLTs

 patch_wurfl.xsl
 Patch WURFL with your own devices, groups and capabilities.
 Example:
 run: xsltproc --stringparam 'file' "your_patch_file" patch_wurfl.xsl wurfl.xml > wurfl_patched.xml
 If you like to format the output (with xmllint):
 run: xsltproc --stringparam 'file' "your_patch_file" patch_wurfl.xsl wurfl.xml | xmllint --format - > wurfl_patched.xml
 If you like to format the output (with tidy):
 run: xsltproc --stringparam 'file' "your_patch_file" patch_wurfl.xsl wurfl.xml | tidy -config tidy_config - > wurfl_patched.xml

 check_wurfl.xsl
 Checks your patched/modified WURFL consistency if:
 id attribute is present and unique
 user_agent attribute is present and unique
 fall_back is available and could be resolved

 Example:
 run: xsltproc check_wurfl.xsl wurfl.xml

 roll out XSLT
 Resolve WURFL fallbacks for all values and capabilities defined in roll_out_capabilities.xml.
 Check the parameters in the XSLT for more options.
 roll_out_into_txt.xsl
 Create text (maybe CSV compatible) version of WURFL.
 Example:
 run: xsltproc roll_out_into_txt.xsl wurfl.xml > wurfl.txt
 roll_out_into_xml.xsl
 Create a flat WURFL version, with each capability as device attribute SQL.
 Example:
 run: xsltproc roll_out_into_xml.xsl wurfl.xml > flat_wurfl.xml
 roll_out_into_sql.xsl
 Create SQL statements for insert WURFL into a SQL database.
 If you like, you can also generate the create statement with this script (default).
 Example:
 run: xsltproc roll_out_into_sql.xsl wurfl.xml > wurfl.sql

 remove_elements.xsl
 WURFL lists many capabilities and groups. If you don't need each of these elements, you will find this tool really useful.
 Create a small XML listing the unwanted groups, run the XSLT and you'll get a new WURFL without the groups and the capabilities that you have selected. This should help you keep WURFL smaller and make your applications faster.
 Example:
 edit remove_elements.xml

 <?xml version="1.0" encoding="UTF-8"?>
 <elements>
 <groups>
 <group>wta</group>
 <group>object_download</group>
 <group>streaming</group>
 <group>wap_push</group>
 <group>j2me</group>
 <group>mms</group>
 <group>sms</group>
 <group>sound_format</group>
 </groups>
 <capabilities>
 <capability>tiff</capability>
 </capabilities>
 </elements>


 run: xsltproc --stringparam 'file' "remove_elements.xml" remove_elements.xsl wurfl.xml > clean_wurfl.xml

 Some (maybe) outdated stylesheets:
 get_capabilities.xsl
 Get capabilities without groups from WURFL for selected user agent.
 Example:
 run: xsltproc --stringparam 'ua' "Nokia3650" get_capabilities.xsl wurfl.xml

 convert_wurfl_markups.xsl
 Convert the WURLF markups to the 'old' names.
 The markup names have changed from wml11 to wml_1_1 standard.
 If you don't want to change your application, you can use this XSLT to transform the names into the old format.
 Example:
 run: xsltproc convert_wurfl_markups.xsl wurfl.xml > wurfl_converted.xml

 count_useragents.xsl
 Answers your question "how many useragents/capabilities are stored in WURFL?"
 Example:
 run: xsltproc count_useragents.xsl wurfl.xml

 convert_2_html.xsl
 Create an HTML page from the WURFL.xml
 Example:
 run: xsltproc convert_2_html.xsl wurfl.xml > wurfl.html

 9 XSLT 2.0 使用 XPath 2.0 和 XSLT 2.0 节省开发时间并减少代码量

==================================================================
10 XSLT中模拟 map与固定次数的循环
 
 <xsl:template name='digital2letter'>
 <xsl:param name='digit' select='0'/>
 <xsl:choose>
 <xsl:when test='$digit = 0'>A</xsl:when>
 <xsl:when test='$digit = 1'>B</xsl:when>
 <xsl:when test='$digit = 2'>C</xsl:when>
 <xsl:when test='$digit = 3'>D</xsl:when>
 <xsl:when test='$digit = 4'>E</xsl:when>
 <xsl:when test='$digit = 5'>F</xsl:when>
 <xsl:when test='$digit = 6'>G</xsl:when>

 <xsl:otherwise>Error Choice</xsl:otherwise>
 </xsl:choose>
 </xsl:template>

 <xsl:template name="AddGeneralChoises">
 <xsl:param name="QuestionID"/>
 <xsl:param name="level" select="0" /> 

 <xsl:if test="$level < 6"> 
 <xsl:variable name="choiceLetter">
 <xsl:call-template name="digital2letter">
 <xsl:with-param name="digit" select="$level"/>
 </xsl:call-template>
 </xsl:variable>

 <xsl:element name="input">
 <xsl:attribute name="type">radio</xsl:attribute>
 <xsl:attribute name="name"><xsl:value-of select="$QuestionID"/></xsl:attribute>
 <xsl:attribute name="choice"> <xsl:value-of select="."/> </xsl:attribute>
 <xsl:attribute name="onfocus"><xsl:text>blur()</xsl:text></xsl:attribute>
 </xsl:element>

 <xsl:value-of select="$choiceLetter"/>
 <xsl:text> </xsl:text>

 <xsl:variable name="levelPlus" select="$level + 1" />

 <xsl:call-template name="AddGeneralChoises"> 
 <xsl:with-param name="QuestionID" select="$QuestionID"/>
 <xsl:with-param name="level" select="$levelPlus"/>
 </xsl:call-template>

 </xsl:if>

 </xsl:template>

==================================================================

 15 xslt 输出方法 outmethod 很重要
 标准文档： http://www.w3.org/TR/xslt#section-XML-Output-Method
 同样一个 html输出成 xml输出成

==================================================================

 16 xslt output method引起的网页显示问题。

 环境：Windows XP SP3 + IE 8.0

 xslt:
 makepaper.xsl: <xsl:output method="xml" encoding="utf-8" omit-xml-declaration="yes" indent="yes"/>

 mainbody.html: <html>

 问题: 输成 IE8对 当成 解析，导致 后面的文字都变成黑体。

 将<xsl:output method="xml" />改为<xs:output method="html" />
 出现新问题，图片不显示，图片链接中的汉字为乱码：
 file:///E:/%25E5%25B1%25B1%25E8%25A5%25BF%25E5%2585%2589%25E7%259B%2598/web/data/demo/image/image2.jpeg

 file:///E:/光盘/web/data/demo/image/image2.jpeg

 最终解决办法：
 更改mainbody.html: 为xhtml格式
 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
 "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
 <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

 xsl的输出格式为xml，xhtml中能正确解析 而不是将之当成 处理。

==================================================================

 17 处理文本结果的技巧
 <xsl:template match="text()">
 <xsl:variable name="parentName" select="name(..)" />

 <xsl:if test='$parentName != "OOXML"'> 
 <xsl:copy-of select="."/>
 </xsl:if>
 </xsl:template>
==================================================================

 18 XSLT 判断XML结点的类型 XSLT

 <?xml version="1.0"?>
 
 

 <xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:doc="http://xsltsl.org/xsl/documentation/1.0"
 xmlns:node="http://xsltsl.org/node"
 extension-element-prefixes="doc node">

 <xsl:template name="node:type">
 <xsl:param name="node" select="."/>

 <xsl:choose>
 <xsl:when test="not($node)"/>
 

 <xsl:when test="$node[1]/self::*"> 
 <xsl:text>element</xsl:text>
 </xsl:when>

 <xsl:when test="$node[1]/self::text()"> 
 <xsl:text>text</xsl:text>
 </xsl:when>

 <xsl:when test="$node[1]/self::comment()"> 
 <xsl:text>comment</xsl:text>
 </xsl:when>

 <xsl:when test="$node[1]/self::processing-instruction()"> 
 <xsl:text>processing instruction</xsl:text>
 </xsl:when>
 <xsl:when test="not($node[1]/parent::*)"> 
 <xsl:text>root</xsl:text>
 </xsl:when>

 
 <xsl:when test="count($node[1] | $node[1]/../namespace::*) = count($node[1]/../namespace::*)">
 <xsl:text>namespace</xsl:text>
 </xsl:when>

 <xsl:when test="count($node[1] | $node[1]/../@*) = count($node[1]/../@*)">
 <xsl:text>attribute</xsl:text>
 </xsl:when>

 </xsl:choose>
 </xsl:template>

 </xsl:stylesheet>

==================================================================

 9 在XSLT载入XML文档，注意XML文件不存在时，为避免在网页报错，需将文件名置空。
 <xsl:variable name="propertyDoc" select="document($propertyFile)"/>
