Xsl实践总结（一）

在一个大型的项目中往往用到好几种开发语言，例如C＃ Java  PHP 。。。
那么如何更好更方便的实现这几种语言之间的相互通讯和结合呢，我下面来介绍一种新的模式，当然已经有很多人用过，但我还是要罗嗦一下：
  通过XML进行交互，每种语言设计的对象类都可以转化为内存中的xml对象，然后每种语言都可以对xml对象进行操作与交互。

最近做了一个项目就是改造以前的程序提升性能，由于以前页面上的构造非常乱而且杂，有从Mysql数据库取数据的，也有从SqlServer数据库取数据的，而且数据库分布在多个服务器上，由于每个项目组之间的协调不够所以在读取数据上有读取重复数据的情况，大大浪费了资源。一个页面上访问数据库很多次，所以造成访问速度非常慢。我们现在设计了一个模式，就是一次性从数据库加载所有的数据然后转化为内存中的xml对象，然后用xsl对数据包装转化为一个带有样式的Html，所有的Js中变量都一次性打到页面上以便使用。

下面介绍几个使用xsl的方法：

XML文件
<?xml version="1.0"?>
<Data>
  <ME>
    <UserID>1</UserID>
    <BasicInfo>
      <UserID>1</UserID>
      <Gender>true</Gender>
      <Age>27</Age>
      <UserName>Eric Liu</UserName>
      <Height>184</Height>
      <Marriage>1</Marriage>
      <Education>2</Education>
      <Income>5</Income>
      <City>861105</City>
      <Desc>南方人了，普通话说不好，人比较笨，父母是农民，自小放牛、插秧、割稻、砍柴都干过了。自己条件也不知道算好还是差，竹竿一只，不过各个部件还算运转正常，长得不好看，父母也没有对不起我了，就是一般一般那种。没车没房，唉，一说这条全国人民都跑了，在别人看来，是在一家还算不错的公司一个也算不错的职位，应该也会有不错的前景。性格比较温和，也比较迷糊，在百合这里就是碰，看看是否可以碰到了。不过我想看完我的介绍，估计所有的鸭子都飞了，唉，坦白也是一种错嘛？

如果有阶层观念或者对父母不是很好的就别和我说话了，我从事IT相关的，但是平时也会给媒体供稿，每天晚上一碗面条就将我养活了</Desc>

1、在xsl中定义变量，用xpath取出数据，然后可以在用于显示的地方进行调用
<xsl:variable name="curUserID" select="Data/ME/BasicInfo/UserID"/>
<xsl:value-of select="$curUserID"/>
2、xsl也可以像导入控件一样来引入另一个xsl 
<xsl:include href="lovetype.xsl"/>
3、条件语句的使用
         <xsl:if test="$oppGender='true'">男</xsl:if>
         <xsl:if test="$oppGender='false'">女</xsl:if>
$oppGender代表一个变量，值为true or  false

这里的if语句没有else部分，要想使用else只能用when

语法如下：

 <xsl:choose>
            <xsl:when test="expression">
            ... some output ...
            </xsl:when>
            <xsl:otherwise>
            ... some output ....
            </xsl:otherwise>
            </xsl:choose>
 

4、for-each 循环语句

<xsl:template match="/"> 
     <TABLE> 
          <xsl:for-each select="//car"> 
               <xsl:sort data-type="text" select="@id"/> 
               <TR> 
                    <TH> 
                         <xsl:text>Car-</xsl:text> 
                         <xsl:value-of select="@id"/> 
                    </TH> 
               </TR> 
          </xsl:for-each> 
     </TABLE> 
</xsl:template>

select 是选取的xml文件的符合条件的节点集合
