我正在尝试使用XSLT转换XML。
下面是我的代码，XML和XSLT
参数：
stylesheetPathname: /home/Jon/XSLT.xsl
inputPathname:/home/Jon/countries.xml
outputPathname:/home/Jon/cTransformedXML.xml
代码：
public static void xmlProcessor(String stylesheetPathname, String inputPathname, String outputPathname ) throws TransformerException {
TransformerFactory factory = TransformerFactory.newInstance();
Source stylesheetSource = new StreamSource(new File(stylesheetPathname));
Transformer transformer = factory.newTransformer(stylesheetSource);
Source inputSource = new StreamSource(new File(inputPathname));
Result outputResult = new StreamResult(new File(outputPathname));
transformer.transform(inputSource, outputResult);
}

下面是在运行eclipse中提到的错误时得到的错误。
"ERROR: 'Could not compile stylesheet'

我有点受不了了，无法弄清楚是什么问题..？
我的XSL或任何代码问题出了点问题。.
请建议..！
答案 0 :(得分：1)
它报告了一个奇怪的文件名错误
'/home/Jon/eclipse-workspace/spark-app/"/home/Jon/XSLT.xsl"
，这向我强烈暗示，提供给xmlProcessor方法的路径与您认为的不一样；要么，要么正在针对一些奇怪的基本目录进行解析。
