正如你所看到的，“非英语单词”变成了一堆废话。我尝试将xslt中的编码更改为“UTF-16”，但它不起作用。这里有人遇到过同样的问题吗

要获得这么多奇怪的字符，您似乎有多个编码问题

首先，将XML读入

XML

字符串时（代码未显示）。在这一点上没有什么帮助，因为我们不知道您是如何出错的，尽管您可能忘记了指定

UTF-8

编码

public String removeEmptyTags(String xml) {
    try (StringWriter out = new StringWriter()) {
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        StreamSource inputXMLSource = new StreamSource(new ByteArrayInputStream(xml.getBytes("UTF-8")));
        StreamSource xsltSource = new StreamSource(getClass().getClassLoader().getResourceAsStream("removeemptytags.xsl"));
        Transformer transformer = transformerFactory.newTransformer(xsltSource);

        transformer.transform(inputXMLSource, new StreamResult(out));
        return out.toString();
    } catch (Exception e) {
        logger.log(Level.SEVERE, "Exception while removing empty tags : ", e);
        throw new ParsingException(e.getMessage());
    }
}

第二，调用

bos.toString（）

时。如果希望结果为

字符串

，请不要使用

输出流

。使用

StringWriter

（请参阅下面的代码）

第三，将字符串写入文件时（代码未显示）。同样，这一点也帮不上什么忙，因为我们不知道您是如何做到的，尽管您可能忘记了指定

UTF-8

编码

public String removeEmptyTags(String xml) {
    try (StringWriter out = new StringWriter()) {
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        StreamSource inputXMLSource = new StreamSource(new ByteArrayInputStream(xml.getBytes("UTF-8")));
        StreamSource xsltSource = new StreamSource(getClass().getClassLoader().getResourceAsStream("removeemptytags.xsl"));
        Transformer transformer = transformerFactory.newTransformer(xsltSource);

        transformer.transform(inputXMLSource, new StreamResult(out));
        return out.toString();
    } catch (Exception e) {
        logger.log(Level.SEVERE, "Exception while removing empty tags : ", e);
        throw new ParsingException(e.getMessage());
    }
}

实际上，最好是直接从/到文件，并让XML库找出编码：

public void removeEmptyTags(Path inFile, Path outFile) {
    try (InputStream in = Files.newInputStream(inFile);
         OutputStream out = Files.newOutputStream(outFile)) {
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        StreamSource xsltSource = new StreamSource(getClass().getClassLoader().getResourceAsStream("removeemptytags.xsl"));
        Transformer transformer = transformerFactory.newTransformer(xsltSource);

        transformer.transform(new StreamSource(in), new StreamResult(out));
    } catch (Exception e) {
        logger.log(Level.SEVERE, "Exception while removing empty tags : ", e);
        throw new ParsingException(e.getMessage());
    }
}
