根据需求xml 创建一个结点以及文件。
public int onCreateEap() {
try {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(new File(FILE_PATH));
Element eapElement = document.createElement("eap");
eapElement.setAttribute("active", "1");
eapElement.setAttribute("options", "8");
eapElement.setAttribute("strict", "0");
Element provisioningElement = (Element) document
.getElementsByTagName("provisioning").item(0);
provisioningElement.appendChild(eapElement);
Element certificateElement = document
.createElement("root-certificate");
certificateElement.setAttribute("encoding", "pem");
Element neweapElement = (Element) document.getElementsByTagName(
"eap").item(0);
Log.d("jcmtest", "readFileData********1");
neweapElement.appendChild(certificateElement);
Element naiElement = document.createElement("nai");
neweapElement.insertBefore(naiElement, certificateElement);
Element newnaiElement = (Element) document.getElementsByTagName(
"nai").item(0);
Log.d("jcmtest", "readFileData********2");
Element prefixElement = document.createElement("prefix");
newnaiElement.appendChild(prefixElement);
Element realmElement = document.createElement("realm");
newnaiElement.insertBefore(realmElement, prefixElement);
Element usernameElement = document.createElement("username");
newnaiElement.insertBefore(usernameElement, realmElement);
Element ttlsElement = document.createElement("ttls");
ttlsElement.setAttribute("active", "1");
neweapElement.insertBefore(ttlsElement, certificateElement);
Log.d("jcmtest", "readFileData********3");
Element outerNaiTypemElement = document
.createElement("outerNaiType");
ttlsElement.appendChild(outerNaiTypemElement);
Element passwordeElement = document.createElement("password");
ttlsElement.insertBefore(passwordeElement, outerNaiTypemElement);
Element typeeElement = document.createElement("type");
ttlsElement.insertBefore(typeeElement, passwordeElement);
TransformerFactory transformerFactory = TransformerFactory
.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource domSource = new DOMSource(document);
transformer.setOutputProperty(OutputKeys.ENCODING, ENCODING);
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.STANDALONE, "yes");
Log.d("jcmtest", "readFileData********4");
File file = new File(FILE_PATH);
FileOutputStream out = new FileOutputStream(file);
StreamResult xmlResult = new StreamResult(out);
transformer.transform(domSource, xmlResult);
Log.d("jcmtest", "readFileData********5");
} catch (Exception ex) {
System.out.println(ex.getMessage());
Log.d("jcmtest", "readFileData********6");
return -1;
}
return 0;
}
根据xml 中的结点数据信息去删除某个结点信息
public int onDeleChannel(Intent intent, int flag) {
try {
int lenth = 0;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(new File(FILE_PATH));

"ndss").item(0);

for (int i = 0; i < nodes.getLength(); i++) {
Element channelElement = (Element) (nodes.item(i));
int oldlenth = channelElement.getElementsByTagName("channel")
.getLength();
lenth = oldlenth;
ArrayList<String> infoList = new ArrayList<String>();
infoList = intent.getStringArrayListExtra("position");
for (String temp : infoList) {
for (int i1 = 0; i1 < lenth; i1++) {
Element channelData = (Element) channelElement
.getElementsByTagName("channel").item(i1);
if (intent != null) {
if (temp.equals(channelData.getAttribute("id"))) {
ndssElement.removeChild(channelData);
}
}
int currentLenth = channelElement.getElementsByTagName(
"channel").getLength();
lenth = currentLenth;
}
}
}
TransformerFactory transformerFactory = TransformerFactory
.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource domSource = new DOMSource(document);
// 设置编码类型
transformer.setOutputProperty(OutputKeys.ENCODING, ENCODING);
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.STANDALONE, "yes");
File file = new File(FILE_PATH);
FileOutputStream out = new FileOutputStream(file);
StreamResult xmlResult = new StreamResult(out);
transformer.transform(domSource, xmlResult);
out.close();
} catch (Exception ex) {
System.out.println(ex.getMessage());
} finally {
this.stopSelf();
Log.d("jcmtest", "delete .......finished");
}
return 0;
}
增加结点信息。
public int onaddChannel(Intent intent) {
try {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();

Document document = db.parse(new File(FILE_PATH));

修改结点信息
