看XSLT，做了點筆記，比較基礎、簡單
基本元素、函數
1。xml文件中處理指令：
<?xml-stylesheet type="text/xsl" href="FitnessCenter.xsl"?>
2。xslt根元素
<xsl:stylesheet xmlns:xsl="??????????????? version="1.0">
3。輸出到屬性：
3.1快速用法：
無效：<Body bgcolor="<xsl:value-of select='/FitnessCenter/Member/FavoriteColor'/>">
有效：<Body bgcolor="{/FitnessCenter/Member/FavoriteColor}">
3.2 用<xsl:attribute輸出屬性：
<TR>
<xsl:attribute name="bgcolor">yellow</xsl:attribute>
4。一般輸出：
<xsl:value-of select="/FitnessCenter/Member/Phone[@type='home']"/>
5。迭代（<xsl:for-each）：
<xsl:for-each select="/FitnessCenter/Member/Phone">
?????? <!--用XPath取得一個XML nodeList-->
????? <TR>
????????? <TD><xsl:value-of select="@type"/></TD>
????????? <TD><xsl:value-of select="."/></TD>
????? </TR>
??? </xsl:for-each>
?? 5.1 XPath用法
????? <xsl:for-each select="/FitnessCenter/Member[position() != last())]">
??????? <!-- 除最后一個元素外都處理 -->
????? </xsl:for-each>
????? <xsl:for-each select="/FitnessCenter/Member[position() >1]">
??????? <!-- 除第一個元素外都處理 -->
????? </xsl:for-each>
????? <xsl:for-each select="/FitnessCenter//Name">
??????? <!-- 取所有以FitnessCenter為輔元素的Name元素 -->
????? </xsl:for-each>
?? 5.2疊代中的序號
????? <xsl:for-each select="/FitnessCenter/Member">
??????? <xsl:number value="position()" format="A"/>
??????? <xsl:text>. </xsl:text>
??????? <xsl:value-of select="Name"/>
??????? <BR/>
????? </xsl:for-each>
????? 其中：format(格式)可取一下值：
????? format=“1” generates the sequence: 1, 2, 3, …
????? format=“01” generates: 01, 02, 03, …
????? format=“A” generates: A, B, C, …
????? format=“a” generates: a, b, c, …
????? format=“I” generates: I, II, III, …
????? format=“i” generates: i, ii, iii, ...
?? 5.3迭代中的排序(<xsl:sort)
????? <xsl:for-each select="/FitnessCenter/Member">
??????? <xsl:sort select="Name" order="ascending"/>
??????? <xsl:value-of select="Name"/>
??????? <BR/>
????? </xsl:for-each>
6。分枝
??? 6.1簡單：
????? <xsl:for-each select="/FitnessCenter/Member[position() > 1]">
??????????????????? Our special offer to platinum members today is ...
??????????????????? <BR/>
????? </xsl:if>
??? 6.2復雜：
??? <xsl:choose>
??????? <xsl:when test='something>
????????????? [action]
??????? </xsl:when>
??????? <xsl:when test='something'>
????????????? [action]
??????? </xsl:when>
??????? <xsl:otherwise>
????????????? [action]
??????? </xsl:otherwise>
??? </xsl:choose>
7。變量(<xsl:variable)
??? 7.1簡單：
?????? <xsl:variable name="pi" select="'3.142857142857'"/>
??? 7.2復雜：
?????? <xsl:variable name="names">
???????? <xsl:value-of select="/FitnessCenter/Member[1]/Name"/>
???????? <xsl:for-each select="/FitnessCenter/Member[position() > 1]">
??????????????????? <xsl:text>/</xsl:text>
??????????????????? <xsl:value-of select="Name"/>
???????? </xsl:for-each>
?????? </xsl:variable>

xslt例子(Coloring alternate rows和兩個Template例子)：
?
1。position() mode 2
例：Coloring alternate rows
<TABLE border="1" width="25%">
??????? <xsl:for-each select="/FitnessCenter/Member">
????????????????? <TR>
????????????????????????? <xsl:if test="position() mod 2 = 0">
??????????????????????????????? <xsl:attribute name="bgcolor">yellow</xsl:attribute>
????????????????????????? </xsl:if>
????????????????????????? <TD><xsl:value-of select="Name"/></TD>
?????????????????? </TR>
???????? </xsl:for-each>
</TABLE>
2。Dument(url) :指向外部另一個Xml文檔
<xsl:variable name="fitnessCenter2"
??????????????? select="document('file://localhost/xml-course/.../FitnessCenter2.xml')"/>
??????? <xsl:for-each select="$fitnessCenter2/FitnessCenter/Member">
3。<xsl:call-template
例：使用帶參數（param）的模板（template）
<xsl:template match="/">
??????? <HTML>
??????????? <HEAD>
??????????????? <TITLE>Fitness Center</TITLE>
??????????? </HEAD>
??????????? <BODY>
??????????????? <xsl:call-template name="displayNameWithFont">
??????????????????? <xsl:with-param name="fontFace" select="'Impact'"/>
??????????????????? <xsl:with-param name="name"
??????????????????????????? select="/FitnessCenter/Member[1]/Name"/>
??????????????? </xsl:call-template>
??????????????? <BR/>
??????????????? ...
??????????? </BODY>
??????? </HTML>
??? </xsl:template>
??? <xsl:template name="displayNameWithFont">
??????? <xsl:param name="fontFace" select="'Braggadocio'"/> <!-- default font -->
??????? <xsl:param name="name"/>
??????? <FONT face="{$fontFace}">
??????????? <xsl:value-of select="$name"/>
??????? </FONT>
??? </xsl:template>
使用帶參數的模板例二：
<xsl:template match="/">
??????? <HTML>
??????????? <HEAD>
??????????????? <TITLE>Fitness Center</TITLE>
??????????? </HEAD>
??????????? <BODY>
??????????????? 16 / 2 =
??????????????? <xsl:variable name="result">
??????????????????? <xsl:call-template name="NumDiv2">
???????????????????????? <xsl:with-param name="N" select="16"/>
??????????????????? </xsl:call-template>
??????????????? </xsl:variable>
??????????????? <xsl:value-of select="$result"/>
??????????? </BODY>
??????? </HTML>
??? </xsl:template>
??? <xsl:template name="NumDiv2">
??????? <xsl:param name="N"/>
??????? <xsl:value-of select="$N div 2"/>
??? </xsl:template>
