不确定我的XSL文档有什么问题，而且我的XML结果文档没有正确重新正确

标签： xml xslt functional-programming

DropBox link to XML file我一直在研究使用函数式编程所需的这个XSL文档，即使它没有错误，结果文档也没有正确呈现，看起来像只有数字的页面和页面没有文字（看起来像机器代码。）。

结果应显示候选人姓名，投票，投票百分比，地区和等于投票时间的条形图。我一直搞乱它，但似乎没有什么改变外观。令我困惑的一些部分是：引用＆＃34;候选人/候选人＆＃34;的全局变量;节点集; cellCount参数等于＆＃34; candidatePercent＆＃34;的值。变量MULTIPLIED 100并四舍五入到最接近的整数;除其他外。

这是我的代码：

XML文档太长了，基本上只包含名称和投票。有人请提供一些指导吗？谢谢。

这是一个XSLT 2.0解决方案。如果您使用浏览器作为转换引擎，请链接到Saxon CE的本地副本。为简洁起见，我将候选数据嵌入到样式表中。我将其留给OP进行微调，以便从外部文档加载候选数据。

输入文档 

<congressResults>
   <district dNumber="1">
      <candidates>
         <candidate candidateID="DFL1">
            <votes precinct="ADAMS" precinctID="0005">263</votes>
            <votes precinct="ADAMS TWP." precinctID="0010">181</votes>
            <votes precinct="ADRIAN" precinctID="0005">349</votes>
            <votes precinct="CITY OF COURTLAND" precinctID="0020">195</votes>
         </candidate>
         <candidate candidateID="DFL2">
            <votes precinct="ADAMS" precinctID="0005">363</votes>
            <votes precinct="ADAMS TWP." precinctID="0010">281</votes>
            <votes precinct="ADRIAN" precinctID="0005">1</votes>
            <votes precinct="CITY OF COURTLAND" precinctID="0020">200</votes>
         </candidate>
      </candidates>
   </district>
</congressResults>
