这次给大家带来往xml中更新节点的ajax方式,往xml中更新节点ajax的注意事项有哪些,下面就是实战案例,一起来看一下。
往xml中更新节点的实例代码
/* System.out.println("2323"); DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder docbuilder = factory.newDocumentBuilder(); Document parse = docbuilder .parse(new File("src/ProdQuery.xml")); // Element createElement2 = parse.createElement(""); Element createElement = parse.createElement("products"); Node item2 = parse.getChildNodes().item(parse.getChildNodes().getLength()-1); for (String item : map.keySet()) { //循环添加至products System.out.println("tianjia1"); Element clidren = parse.createElement("product"); Attr createAttribute = parse.createAttribute("name"); createAttribute.setNodeValue(item); Attr createAttribute2 = parse.createAttribute("value"); createAttribute2.setNodeValue(map.get(item)); clidren.setAttributeNode(createAttribute); clidren.setAttributeNode(createAttribute2); createElement.appendChild(clidren); } //将products添加到根目录 item2.appendChild(createElement); //创建一个TransformerFactory对象 TransformerFactory tFactory = TransformerFactory.newInstance(); //得到一个操作对象 Transformer transformer = tFactory.newTransformer(); //设置们,这个是编码 transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8"); // DOMSource source = new DOMSource(parse); System.out.println("改变文件"); StreamResult result = new StreamResult(new File("src/ProdQuery.xml")); //让xml文件换行 transformer.setOutputProperty(OutputKeys.INDENT, "yes"); transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4"); transformer.transform(source, result);*/
