Transformer我使用類和轉換方法修改 XML 文件。它正確地修改了我的參數(shù)但改變了 XML 樣式（以不同的方式編寫 XML 屬性）：原來的：<a struct="b"></a><c></c>編輯后：<a struct="b"/><c/>我知道我可以設置屬性：transformer.setOutputProperty(OutputKeys.KEY,value),但我沒有找到合適的設置。誰能幫助變壓器不改變寫入格式？XMLReader xr = new XMLFilterImpl(XMLReaderFactory.createXMLReader()Source src = new SAXSource(xr, new InputSource(new StringReader(xmlArray[i])));<<modify xml>>TransformerFactory transFactory = TransformerFactory.newInstance();Transformer transformer = transFactory.newTransformer();          transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION,"yes");           StringWriter buffer = new StringWriter();            transformer.transform(src, new StreamResult(buffer));            xmlArray[i] = buffer.toString();
