I want to parse "ALışVERIş" type of content from service.
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
myXMLHandler = new XMLHandler();
xr.setContentHandler(myXMLHandler);
URL _url = new URL(params[0]);
xr.parse(new InputSource(_url.openStream()));
What I tried DOM Parser instead of XaxParser. Check below function and call it inside background thread :
public String readXML(){
StringBuilder stringBuilder = new StringBuilder();
try {
URL _url = new URL("http://182.160.161.2/~siva/turkish/web_serv/category.php?order_by=desc&category_id=2");
File fXmlFile = new File(new InputSource(_url.openStream()).getByteStream().toString());
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(new InputSource(_url.openStream()).getByteStream());
//optional, but recommended
//read this - http://stackoverflow.com/questions/13786607/normalization-in-dom-parsing-with-java-how-does-it-work
doc.getDocumentElement().normalize();
System.out.println("Root element :" + doc.getDocumentElement().getNodeName());
NodeList nList = doc.getElementsByTagName("document");
Node nResp = nList.item(0);
Element fstElmnt = (Element) nResp;
NodeList nameList1 = fstElmnt.getElementsByTagName("response");
Node mCat = nameList1.item(0);
Element catElmt = (Element) mCat;
NodeList catList = catElmt.getElementsByTagName("category");
System.out.println("----------------------------");
for (int temp = 0; temp < catList.getLength(); temp++) {
Node nNode = catList.item(temp);
System.out.println("\nCurrent Element :" + nNode.getNodeName());
if (nNode.getNodeType() == Node.ELEMENT_NODE) {
Element eElement = (Element) nNode;
stringBuilder.append("Category ID : " + eElement.getElementsByTagName("category_name").item(0).getTextContent()+"\n");
stringBuilder.append("Category Name : " + eElement.getElementsByTagName("category_id").item(0).getTextContent());
System.out.println("Category ID : " + eElement.getElementsByTagName("category_name").item(0).getTextContent());
System.out.println("Category Name : " + eElement.getElementsByTagName("category_id").item(0).getTextContent());
}
}
} catch (Exception e) {
e.printStackTrace();
}
return stringBuilder.toString();
}

I have xml:
<Info>
<info_1/>
<info_2/>
<info_3>
<i ID="1"/>
<i ID="2"/>
<i ID="3"/>
</info_3>
<info_4>
</indo_4>
</Info>
I need to delete a specific node in info_3, for example a node in which ID = 1, how can I do this?
I tried to do this, but log shows before and after length = 3 :
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(new InputSource(new StringReader(bb)));
doc.getDocumentElement().normalize();
NodeList nList = doc.getElementsByTagName("i");
Log.e("LOG", "nList.getLength() = " + nList.getLength());
Node node=nList.item(1);
node.getParentNode().removeChild(node);
Log.e("LOG", "nList.getLength() = " + nList.getLength());
Solution that helped me:
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(new InputSource(new StringReader(bb)));
doc.getDocumentElement().normalize();
NodeList nList = doc.getElementsByTagName("i");
Log.e("LOG", "nList.getLength() = " + nList.getLength());
Set<Element> targetElements = new HashSet<>();
for (int i = 0; i < nList_Loan_guarantor.getLength(); i++) {
Element e = (Element)nList_Loan_guarantor.item(i);
if ("10938".equals(e.getAttribute("ID"))) {
targetElements.add(e);
}
}
for (Element e: targetElements) {
e.getParentNode().removeChild(e);
}
doc.getDocumentElement().normalize();
NodeList nList_2 = doc.getElementsByTagName("i");
Log.e("LOG", "nList.getLength() = " + nList.getLength());
Here is my code. I want to see these parsed strings into ListView in Android. How can I do this?
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(xmlRecords));
Document doc = db.parse(is);
NodeList nodes = doc.getElementsByTagName("employee");
for (int i = 0; i < nodes.getLength(); i++) {
Element element = (Element) nodes.item(i);
NodeList name = element.getElementsByTagName("name");
Element line = (Element) name.item(0);
System.out.println("Name: " + getCharacterDataFromElement(line));
NodeList title = element.getElementsByTagName("title");
line = (Element) title.item(0);
System.out.println("Title: " + getCharacterDataFromElement(line));
}
}
public static String getCharacterDataFromElement(Element e) {
Node child = e.getFirstChild();
if (child instanceof CharacterData) {
CharacterData cd = (CharacterData) child;
return cd.getData();
}
return "";
}
}

I have doc for loop. but how to connect local xml file in doc parser. i don't want url model, i want to a local xml file.
for (int i = 0; i < nodeList.getLength(); i++) {

put you XML file in assets folder and Try this way
String xml;
Document doc;
try{
xml=getXML(getAssets().open("yourxmlfilename.xml"));
}catch(Exception e){

Document document = db.parse(in, null);
I am having some trouble parsing XML in Android from an URL. I don't know if it's the XML parsing that's the problem or only when I am trying to show it on the screen because
setListAdapter(new ArrayAdapter<String>(ANDROIDXMLActivity.this, android.R.layout.simple_list_item_1, stopNumbers));
wont show anything. The code below works perfectly in a java program.

Solved it. I had forgot to add internet permission in the manifest.
I am consuming a web service as its output is an XML string. I am parsing it into a document and getting each child node value one by one and inserting into my SQLlite table as shown below:

String SOAP_ACTION = "http://VisionEPODWebService/GetProblemAndReasonCodesNew";
String OPERATION_NAME = "GetProblemAndReasonCodesNew";
String WSDL_TARGET_NAMESPACE = "http://VisionEPODWebService/";
String SOAP_ADDRESS = "";
SOAP_ADDRESS = "http://" + serverIPAddress
+ "/VisionEPODWebService/SystemData.asmx";
SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,
OPERATION_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER10);
request.addProperty("deviceID", deviceId);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);
try {
httpTransport.call(SOAP_ACTION, envelope);
Object response = envelope.getResponse();

.getElementsByTagName("tblProblemCode");

dbAdapter = new DatabaseAdapter(this.context);
dbAdapter.open();
dbAdapter.BeginTransaction();

for (int i = 0; i < nodesProblemCode.getLength(); i++) {

public static String getCharacterDataFromElement(Element e) {

if (child instanceof CharacterData) {

}
return "?";
}
The problem is that after some time the XML string will not have some of child node. For example
"ProblemCode" child node.....at that time the code shows error.
How can I check whether there exists an element in the document, or whether values exist or not for the element?
I think you need to check if the child node exists: specifically for your problem node:
NodeList NL = element.getElementsByTagName("PKProblemCode");
if ((NL==null)||(NL.getLength()==0)) {
//No such node so use a default instead
} else
Element line = (Element) PKProblemCode.item(0);
