org.w3c.dom.Document to String without javax.xml.transform
提问by Kurru
I've spent a while looking around on Google for a way to convert a org.w3c.dom.Document to a string representation of the whole DOM tree, so I can save the object to file system.
我花了一段时间在 Google 上四处寻找将 org.w3c.dom.Document 转换为整个 DOM 树的字符串表示的方法，以便我可以将对象保存到文件系统。
However all the solutions I've found use javax.xml.transform.Transformer which isn't supported as part of the Android 2.1 API. How can I do this without using this class/containing package?
但是，我发现的所有解决方案都使用 javax.xml.transform.Transformer，它不作为 Android 2.1 API 的一部分提供支持。如何在不使用此类/包含包的情况下执行此操作？

Please try this code:
请试试这个代码：
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.parse("/path/to/file.xml");
DOMImplementation domImpl = ownerDocument.getImplementation();
DOMImplementationLS domImplLS = (DOMImplementationLS)domImpl.getFeature("LS", "3.0");
LSSerializer serializer = domImplLS.createLSSerializer();
serializer.getDomConfig().setParameter("xml-declaration", Boolean.valueOf(false));
LSOutput lsOutput = domImplLS.createLSOutput();
lsOutput.setCharacterStream(output);
serializer.write(doc, lsOutput);
