往xml中更新节点的ajax方式

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productsSystem.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("{xml.apache.org/xslt}indent-amount", "4");transformer.transform(source, result);*/
