xml解析

 

读取xml

DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();

DocumentBuilder builder = builderFacotry.newDocumentBuilder();

Document document = builder.Parse(getAssets().open("lang.xml"));//在builder中传入xml位置

Element element = document.getDocumentElement();//根节点

NodeList list = element.getElementsByTagName("lan");

for(list){lan.getAttribute("id");lan.getElementByTagName("name").item(0).getTextContent();}

 

 

存xml

Document newxml = builder.newDocument();

Element languages = newxml.createElement("language");

languages.setAttribute("id",it);

Element lan1 = newxml.createElement("lan");

lan1.setAttibute("id","1");

Element name1 = newxml.createElement("name");

name1.setText(ontxt1,"Java");

lan1.appendChild(name1);

languages.appendChilde(lan1);

newxml.appendChild(language);

TransFormFactory transF = TrasFormFactory.newInstace();

Transformer trans = transF.newTransFormer();

trans.setOutputProperty("encoding","UTF-8");

trans.transform(new DoMSource(newXml),new StreamResult(OutputStreamWriter));

sw.toString();
