我是这个java脚本和xsl的新手。 我们使用.js将.csv文件转换为xml，使用.js代码中的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。任何帮助都将非常感激。

我不知道如何附加我的.csv文件。但这个代码有什么方法可以让它更好???请分享您的想法。
/ *示例.csv文件数据* / RebateInvoiceID RebateEventID BusinessUnitCode CategoryID PaymentAmount 1001655 1002652 406 1000043 696.81 1001655 1002650 423 1000043 8.85 1001655 1002652 423 1000043 443.39 1001655 1002650 433 1000043 15.93 3001655 8002652 433 1000043 432.29 3001655 8002652 434 1000043 55.46 3001655 8002653 434 1000043 590.6 3001655 8002653 435 1000043 10.03 5001655 2002652 435 1000043 329.31 5001655 2002652 436 1000043 21.83 5001655 2002655 436 1000043 501.71 5001655 2002655 437 1000043 32.45 5001655 2002655 437 1000043 674.81

此代码：
<xsl:for-each select="//Document/RawXMLRow[not(RebateInvoiceID=preceding-
sibling::RawXMLRow/RebateInvoiceID)]">
是一种非常低效的分组（或消除重复）的方法 - 性能是数据中行数的二次方。假设您遇到了XSLT 1.0，请使用密钥查看Muenchian分组。
