Java: Saving StreamResult to a file
提问by Todd
I am doing some data conversion(like csv) to xml with SAX then using transformer in Java. The result is in StreamResult, and I am trying to save this result to a file.xml but I can't find way to save StreamResult into file. am I doing this all wrong?
我正在使用 SAX 将一些数据转换（如 csv）转换为 xml，然后在 Java 中使用转换器。结果在 StreamResult 中，我试图将此结果保存到 file.xml，但我找不到将 StreamResult 保存到文件中的方法。我做这一切都错了吗？

Your StreamResultshould be created on the basis of a file, e.g.
您StreamResult应该基于文件创建，例如
StreamResult sr = new StreamResult(new File("/my/file.xml"));
If you give your Transformersuch a StreamResult, it will write its result directly into the file you specified.
如果你给你Transformer这样的 a StreamResult，它会直接将结果写入你指定的文件中。

I am not familiar with the API... but does this linkgive you what you are after?
我不熟悉 API ......但是这个链接是否给了你你想要的东西？
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
//initialize StreamResult with File object to save to file
StreamResult result = new StreamResult(new StringWriter());
DOMSource source = new DOMSource(doc);
transformer.transform(source, result);
String xmlString = result.getWriter().toString();
System.out.println(xmlString);
