我是这个 java 脚本和 xsl 的新手。我们正在使用 .js 将 .csv 文件转换为 xml，在 .js 代码中使用 xsl。

它会产生很多性能问题，并且不会为某些 .csv 文件创建任何 xml 文件。任何帮助将不胜感激。

showAbsolutePath("InvoiceAdjustment.js");

function showAbsolutePath(path)
 {
 var fso = new ActiveXObject("Scripting.FileSystemObject");
 var s = "";
 s += fso.GetAbsolutePathName(path);

 var foldername = s.substring(0,s.indexOf(path,0));

 }

  var fso, f, fc, filename;

 fso = new ActiveXObject("Scripting.FileSystemObject");
  f = fso.GetFolder(foldername);
 fc = new Enumerator(f.files);

 for (; !fc.atEnd(); fc.moveNext())
 {
  filename = "";
  filename += fc.item();

  if (filename.slice(-4) == ".csv")
  {
    convertCSVtoXML(foldername, filename);
    }
   }  

  fso = null;

 // Open the extracted csv from zip file
 var fso = new ActiveXObject("Scripting.FileSystemObject");

 var csvFilename = filename;

 var tso = fso.OpenTextFile(csvFilename, 1);

我不知道如何附加我的 .csv 文件。但是这个代码有什么办法可以让它变得更好吗？？？请分享你的想法。

这段代码：

<xsl:for-each select="//Document/RawXMLRow[not(RebateInvoiceID=preceding- 
             sibling::RawXMLRow/RebateInvoiceID)]">

重复出现是一种非常低效的分组（或消除重复项）方式 - 性能与数据中的行数成二次方。假设您坚持使用 XSLT 1.0，请查看使用键的 Muenchian 分组。
