java xml解析之JAXP

获得xml文档的document树

Document document = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse("xxxx");

操作方法和js操作html一致，creatElement,appendChild等方法都是一样的

将修改后的document数写入xml文件

Transformer transformer = TransformerFactory.newInstance().newTransformer();

transformer.transform(new DOMSource(document), new StreamResult("xxxxx"));
