I am using the following code for parsing an XML file. But I don't get any response. Can anyone help?
I am also getting a warning when I open a connection:
"Warning!: Invocation of questionable method: java.lang.String.() found"`?
public static void main(String arg[]){
XML_Parsing_Sample application = new XML_Parsing_Sample();
//create a new instance of the application
//and start the application on the event thread
application.enterEventDispatcher();
}
public XML_Parsing_Sample() {
_screen.setTitle("XML Parsing");//setting title
_screen.add(new RichTextField("Requesting....."));
_screen.add(new SeparatorField());
pushScreen(_screen); // creating a screen
//creating a connection thread to run in the background
_connectionthread = new Connection();
_connectionthread.start();//starting the thread operation
}
public void updateField(String node, String element){
//receiving the parsed node and its value from the thread
//and updating it here
//so it can be displayed on the screen
String title="Title";
_screen.add(new RichTextField(node+" : "+element));
if(node.equals(title)){
_screen.add(new SeparatorField());
}
}
private class Connection extends Thread{
public Connection(){
super();
}
public void run(){
// define variables later used for parsing
Document doc;
StreamConnection conn;
try{
//providing the location of the XML file,
//your address might be different
conn=(StreamConnection)Connector.open
("http://www.w3schools.com/xml/note.xml",Connector.READ);
//next few lines creates variables to open a

//node and the values of an element
DocumentBuilderFactory docBuilderFactory

DocumentBuilder docBuilder

docBuilder.isValidating();
doc = docBuilder.parse(conn.openInputStream());
doc.getDocumentElement ().normalize ();
NodeList list=doc.getElementsByTagName("*");
_node=new String();
_element = new String();
//this "for" loop is used to parse through the
//XML document and extract all elements and their
//value, so they can be displayed on the device
for (int i=0;i<list.getLength();i++){
Node value=list.item(i).
getChildNodes().item(0);
_node=list.item(i).getNodeName();
_element=value.getNodeValue();
updateField(_node,_element);
}//end for
}//end try
//will catch any exception thrown by the XML parser
catch (Exception e){
System.out.println(e.toString());
}
}//end connection function
}// end connection class
You are probably timing out.
Try opening the connection as HTTP connection instead, and use the new ConnectionFactory class to get rid of annoying suffixes.
public InputStream getResult(String url) {
System.out.println("in get result");
HttpConnection httpConn;
httpConn = (HttpConnection) getHTTPConnection(url);
try {
if (httpConn != null) {
final int iResponseCode = httpConn.getResponseCode();
if (iResponseCode == httpConn.HTTP_OK) {
_inputStream = httpConn.openInputStream();
byte[] data = new byte[20];
int len = 0;
int size = 0;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
try {
while (-1 != (len = _inputStream.read(data))) {
baos.write(data, 0, len);
size += len;
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
InputStream is2 = new ByteArrayInputStream(
baos.toByteArray());
return is2;
} else {
return null;
}
}
} catch (IOException e) {
System.err.println("Caught IOException: " + e.getMessage());
}
try {
httpConn.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
To download xml

Then parse this document in to element

rootElement.normalize();
displayNode( rootElement, 0 );
private void displayNode( Node node, int depth )

You can download and parse the xml using above sample.
NamedNodeMap attributes = (NamedNodeMap)value.getAttributes();
for (int g = 0; g < attributes.getLength(); g++) {
Attr attribute = (Attr)attributes.item(g);
System.out.println(" Attribute: " + attribute.getName() +
" with value " +attribute.getValue());
Above code fetches attributes and its values.. cheers

From your code, it looks like your XML will end up as
<Question ...></Question>
<Question ...></Question>
You cannot have multiple root elements in an XML document. You could try wrapping all your Question elements in a root element, like
<Questions>
<Question ...></Question>
<Question ...></Question>
</Questions>
Just ensure you only have one element as the root of the contents you are converting
I am doing Bulk Upload Task in Alfresco.
Before this i created custom action to call java code, i also successfully read data from excel sheet, and i found node reference of target document as well as source Document. Using that node reference i am also able to create new multiple Documents.
Now My requirement is, I want to replace Excel Data in that newly created Document. I tried to replace it, But It replacing the String only in First line of document, and it also deleting Rest of the existing contents inside newly created document. I have written Below code for this.
In below code i am first simply trying to replace some hard coded data to the Document.
But My requirement is i want to replace the data inside document which i already read from excel file.

Its not possible to take direct file stream object in alfresco.
so i created one file at local drive, in background i performed all replacement operations. and after that i read all data using file input stream object. and later i used file that stream with node.
and it gave me my desired output. :)
I have this xml online http://64.182.231.116/~spencerf/test.xml
And I am trying to get the two text values Assorted Cereal and Yogurt Parfait (2). Here is how I am currently parsing it, and I get the values I want as well as all the values under then, all the numbers and such, but I just want to get the names, and I am struggling how to just do that, any help or guidance would be great. Here is my code:
String currentDay = "";
String currentMeal = "";
String counter = "";
String icon1 = "";
LinkedHashMap<String, List<String>> itemsByCounter = new LinkedHashMap<String , List<String>>();
List<String> items = new ArrayList<String>();
while (eventType != XmlResourceParser.END_DOCUMENT) {
String tagName = xmlData.getName();
switch (eventType) {
case XmlResourceParser.START_TAG:
if (tagName.equalsIgnoreCase("day")) {
currentDay = xmlData.getAttributeValue(null, "name");
}
if (tagName.equalsIgnoreCase("meal")) {
currentMeal = xmlData.getAttributeValue(null, "name");
}
if (tagName.equalsIgnoreCase("counter") && currentDay.equalsIgnoreCase(day) && currentMeal.equalsIgnoreCase(meal)) {
counter = xmlData.getAttributeValue(null, "name");
}
if (tagName.equalsIgnoreCase("name") && counter != null && currentDay.equalsIgnoreCase(day) && currentMeal.equalsIgnoreCase(meal)) {
icon1 = xmlData.getAttributeValue(null, "icon1");
Log.i(TAG, "icon1: " + icon1);
}
break;
case XmlResourceParser.TEXT:
if (currentDay.equalsIgnoreCase(day) && currentMeal.equalsIgnoreCase(meal) && counter !=(null)) {
if (xmlData.getText().trim().length() > 0) {
//Here gets everything but I just want 2 names
Log.i(TAG, "data: " + xmlData.getText());
items.add(xmlData.getText().trim().replaceAll(" +", " "));
}
}
break;
case XmlPullParser.END_TAG:
if (tagName.equalsIgnoreCase("counter")) {
if (items.size() > 0) {
itemsByCounter.put(counter, items);
items = new ArrayList<String>();
recordsFound++;
}
}
break;
}
eventType = xmlData.next();
So as you can see in the comment in my code I am getting everything under the name tag, back but I just want the value of the name, and not all the other stuff.
You will need to store the name in its own child element (meaning put an end tag before the nutritional facts). Under each dish, you could have this:
<name>Assorted Cereal</name>
<nutrition_facts> ... </nutrition_facts>
Not tested but could do it along these lines:
List<Nutrition_Facts> nutrition_facts = new ArrayList<Nutrition_Facts>();
XMLDOMParser parser = new XMLDOMParser();
AssetManager manager = context.getAssets();
InputStream stream;
try {
stream = manager.open("test.xml"); //need full path to your file here - mine is stored in assets folder
Document doc = parser.getDocument(stream);
}catch(IOException ex){
System.out.printf("Error reading map %s\n", ex.getMessage());
}
NodeList nodeList = doc.getElementsByTagName("nutrition_facts");
for (int i = 0; i < nodeList.getLength(); i++) {
Element e = (Element) nodeList.item(i);
String name;
if (elementName.equals(e.getAttribute("Assorted Cereal"))){
name = e.getAttribute("name");
//do some stuff
}
}

I am fairly new to Java, at least regarding interacting with web. Anyway, I am making an app that has to grab HTML out of a webpage, and parse it.
By parsing I mean finding out what the element has in the 'class="" ' attribute, or in any attribute available in the element. Also finding out what is inside the element. This is where I have searched so far: http://www.java2s.com/Code/Java/Development-Class/HTMLDocumentElementIteratorExample.htm
I found very little regarding this.
I know there are lots of Java parsers out there. I have tried JTidy, and the default Swing parser. I would prefer to use the built-in-to-java parser.
Here is what i have so far (this is just method for testing how it works, proper code will come when i know what & how. Also connection is a URLConnection variable, and connection has been established before this method gets called. < just to clarify):
public void parse() {
try {
InputStream is = connection.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
// copied from http://www.java2s.com/Code/Java/Development-Class/HTMLDocumentElementIteratorExample.htm
HTMLEditorKit htmlKit = new HTMLEditorKit();
HTMLDocument htmlDoc = (HTMLDocument) htmlKit.createDefaultDocument();
HTMLEditorKit.Parser parser = new ParserDelegator();
HTMLEditorKit.ParserCallback callback = htmlDoc.getReader(0);
parser.parse(br, callback, true);
// Parse
ElementIterator iterator = new ElementIterator(htmlDoc);
Element element;
while ((element = iterator.next()) != null) {
AttributeSet attributes = element.getAttributes();
Object name = attributes.getAttribute(StyleConstants.NameAttribute);
System.out.println ("All attrs of " + name + ": " + attributes.getAttributeNames().toString());
Enumeration e = attributes.getAttributeNames();
Object obj;
while (e.hasMoreElements()) {
obj = e.nextElement();
System.out.println (obj.toString());
System.out.println ("attribute of class = " + attributes.containsAttribute("class", "login"));
}
if ((name instanceof HTML.Tag)
&& ((name == HTML.Tag.H1) || (name == HTML.Tag.H2) || (name == HTML.Tag.H3))) {
// Build up content text as it may be within multiple elements
StringBuffer text = new StringBuffer();
int count = element.getElementCount();
for (int i = 0; i < count; i++) {
Element child = element.getElement(i);
AttributeSet childAttributes = child.getAttributes();
if (childAttributes.getAttribute(StyleConstants.NameAttribute) == HTML.Tag.CONTENT) {
int startOffset = child.getStartOffset();
int endOffset = child.getEndOffset();
int length = endOffset - startOffset;
text.append(htmlDoc.getText(startOffset, length));
}
}
System.out.println(name + ": " + text.toString());
}
}
} catch (IOException e) {
System.out.println ("Exception?1 " + e.getMessage() );
} catch (Exception e) {
System.out.println ("Exception? " + e.getMessage());
}
}
The question is: How do I get any element's attributes and print them out?
This code is needlessly verbose. I would suggest using a better library like Jsoup. Here's some code to find out all the attributes of all divs on this page.
String url = "http://stackoverflow.com/questions/7311269"
+ "/java-print-any-detail-of-html-element";
Document doc = Jsoup.connect(url).get();
Elements divs = doc.select("div");
int i = 0;
for (Element div : divs) {
System.out.format("Div #%d:\n", ++i);
for(Attribute attr : div.attributes()) {
System.out.format("%s = %s\n", attr.getKey(), attr.getValue());
}
}
Follow the Jsoup Cookbook for a gentle introduction to the this powerful library.
I'm trying to read a Collada XML file by iterating through a child node list, and every other output reads #text. What's this about? My code:
public void runTest() {
File file = new File( "test.dae" );
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
try {
builder = factory.newDocumentBuilder();
}
catch( ParserConfigurationException error ) {
System.out.println( "--ParserConfigurationException: " + error.getMessage() ); return;
}
Document document = null;
try {
document = builder.parse( file );
}
catch( IOException error ) {
System.out.println( "--IOException: " + error.getMessage() ); return;
}
catch( SAXException error ) {
System.out.println( "--SAXException: " + error.getMessage() ); return;
}
Node node = document.getDocumentElement();
String node_name = node.getNodeName();
System.out.println( node_name );
NodeList node_list = node.getChildNodes();
for( int iterator = 0; iterator < node_list.getLength(); iterator++ ) {
Node child_node = node_list.item( iterator );
String child_node_name = child_node.getNodeName();
System.out.println( "-- " + child_node_name );
}
}
"#text" is simply the result of calling the getNodeName() method on a Text node. (As you will see if you look at the API documentation for org.w3c.dom.Node.) If you want the actual text contents of the node, you would use the getNodeValue() method.
And if you weren't expecting there to be any Text nodes, don't forget that even little bits of whitespace, like new-line characters, are treated as text.
