使用.JS和XSL的性能和轉換問題

Question

我是新來的這個Java腳本和xsl。 我們使用.js將.csv文件轉換爲xml，使用.js代碼中的xsl。

它創造了很多性能問題，它不會爲某些.csv文件創建任何xml文件。任何幫助將非常感激。

我不知道如何附加我的.csv文件。但是，這個代碼有什麼辦法可以讓它變得更好？請分享你的想法。

Answer 1

此代碼：

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

，其重複出現

，是這樣做的分組的非常低效的方式（或重複的消除） - 性能是在二次數據中的行數。假設你停留在XSLT 1.0中，請使用鍵查看Muenchian分組。
