dom方式是Java官方生成xml文件的方式。其当时如下： 首先，创建一个DocumentBuilderFactory的对象 DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db =null; 具体实现过程参照程序：(下边的程序是一个方法，所需要的包附在最后) public void creatXml(){ DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance(); try { DocumentBuilder db=dbf.newDocumentBuilder(); Document doc=db.newDocument(); doc.setXmlStandalone(ture); Element bookstore=doc.createElement("bookstore"); doc.appendChild(bookstore); Element book=doc.createElement("book"); bookstore.appendChild(book); book.setAttribute("id", "1"); Element name=doc.createElement("name"); book.appendChild(name); name.setTextContent("小王子"); TransformerFactory tff=TransformerFactory.newInstance(); try { Transformer tf=tff.newTransformer(); try { tf.transform(new DOMSource(doc), new StreamResult(new File("books1.xml"))); } catch (TransformerException e) { // TODO Auto-generated catch block e.printStackTrace(); } } catch (TransformerConfigurationException e) { // TODO Auto-generated catch block e.printStackTrace(); } } catch (ParserConfigurationException e) { // TODO Auto-generated catch block e.printStackTrace(); } } import java.io.File;
