This is My XML[XBRL], i need to parse this. This xml is my input and i don't know whether its a valid or not but in need output like this :
<div style="font-family:Times New Roman;font-size:10pt;"><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Other Income (Expense)</font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"></font></div></div>
Please someone share me the knowledge for this problem i am facing from last two weeks.
this is the code i am using
File fXmlFile = new File("/home/devteam-user1/Desktop/ky/UnitTesting.xml");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(fXmlFile);
XPath xPath = XPathFactory.newInstance().newXPath();
final String DIV_UNDER_ROOT = "/*/aoi";
NodeList divList = (NodeList)xPath.compile(DIV_UNDER_ROOT)
.evaluate(doc, XPathConstants.NODESET);
System.out.println(divList.getLength());
for (int i = 0; i < divList.getLength() ; i++) { // just in case there is more than one
Node divNode = divList.item(i);
System.out.println(nodeToString(divNode));
//nodeToString method below
private static String nodeToString(Node node) throws Exception
{
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
StreamResult result = new StreamResult(new StringWriter());
transformer.transform(new DOMSource(node), result);
return result.getWriter().toString();
}

this works well for me
public static void main(String[] args) throws IOException {
FileInputStream fis = new FileInputStream("yourfile.xml");
Document doc = Jsoup.parse(Utils.streamToString(fis));
System.out.println(doc.select("aoi|OtherIncomeAndExpensePolicyTextBlock").html().toString());
}

Your main issue lies with
final String DIV_UNDER_ROOT = "/*/aoi";
Which is an XPath expression that matches "any node 2 levels under the root, which has a local name of aoi and no namespace". This is not what you want.
You want to match any contents of a node that is two levels deep, whose namespace is aliased by "aoi" (which means it belongs to the "http://www.aointl.com/20160331" namespace), and whose local name is "OtherIncomeAndExpensePolicyTextBlock".
Matching namespaces in XPath in Java is quiet cumbersome (see XPath with namespace in Java and How to query XML using namespaces in Java with XPath?), but long story short, you could try this way instead :
final String DIV_UNDER_ROOT = "//*[local-name()='OtherIncomeAndExpensePolicyTextBlock' and namespace-uri()='http://www.aointl.com/20160331']/*";
This will only work if your DocumentBuilderFactory is made namespace aware, so you should make sure by configuring it like so above :
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
dbFactory.setNamespaceAware(true);

How to append new nodes to an existing xml file

Hello Im new in useing xml and now trying to append new nodes for existing xml file.
This is my code to write a xml
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBulder = docFactory.newDocumentBuilder();
//root mainElement
Document doc = docBulder.newDocument();
Element rootElement = doc.createElement("Books");
doc.appendChild(rootElement);
//root Book
Element Book = doc.createElement("Book");
rootElement.appendChild(Book);
//setting ganre for a book
Attr att = doc.createAttribute("ganre");
att.setValue(ganre);
Book.setAttributeNode(att);
//book id
Element bookId = doc.createElement("bookId");
bookId.appendChild(doc.createTextNode(randomString(4)));
Book.appendChild(bookId);
//bookname element
Element bookname = doc.createElement("bookName");
bookname.appendChild(doc.createTextNode(name));
Book.appendChild(bookname);
//book author
Element bookAuthor = doc.createElement("bookAuthor");
bookAuthor.appendChild(doc.createTextNode(author));
Book.appendChild(bookAuthor);
//book year
Element bookYear = doc.createElement("bookYear");
bookYear.appendChild(doc.createTextNode(String.valueOf(year)));
Book.appendChild(bookYear);
//book available
Element bookAvail = doc.createElement("bookAvailable");
bookAvail.appendChild(doc.createTextNode(String.valueOf(free)));
Book.appendChild(bookAvail);
//write in a XMLFile
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File("Test/Books.xml"));
transformer.transform(source, result);
System.out.println("File saved!");
this is how I trying to append new nodes
File fXmlFile = new File("Test/Books.xml");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(fXmlFile);
Node books = doc.getFirstChild();
Element newBook = doc.createElement("Book");
[here the troubles comes]
what i want to do is rewrite file like this:
<Books>
<Book ganre="fantasy">
<bookId>7111</bookId>
<bookName>Tron</bookName>
<bookAuthor>Brawm</bookAuthor>
<bookYear>15</bookYear>
<bookAvailable>true</bookAvailable>
</Book>
<Book ganre="action">
<bookId>312</bookId>
<bookName>Corn</bookName>
<bookAuthor>Down</bookAuthor>
<bookYear>23</bookYear>
<bookAvailable>false</bookAvailable>
</Book>
</Books>
but every time Im can only rewrite or damage the xml file.
ps Im getting all my bookName's and so on from the input

I can just suggest to use the JDom library. Its very easy to use and implement, always worked for me.
JDOM is, quite simply, a Java representation of an XML document. JDOM provides a way to represent that document for easy and efficient reading, manipulation, and writing. It has a straightforward API, is a lightweight and fast, and is optimized for the Java programmer. It’s an alternative to DOM and SAX, although it integrates well with both DOM and SAX.
There are some good tutorials at mykong.com explaining how to read, modify and create xml-files :
http://www.mkyong.com/java/how-to-modify-xml-file-in-java-jdom/

problem was solved. My solution is:
File fXmlFile = new File("Test/Books.xml");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(fXmlFile);
// doc.getDocumentElement().normalize();
Element nList = doc.getDocumentElement();
System.out.println("-----------------------");
//root a new book
Element newBook = doc.createElement("Book");
//setting ganre for a book
Attr att = doc.createAttribute("ganre");
att.setValue(ganre);
newBook.setAttributeNode(att);
//book id
Element bookId = doc.createElement("bookId");
bookId.appendChild(doc.createTextNode(randomString(4)));
newBook.appendChild(bookId);
//bookname element
Element bookname = doc.createElement("bookName");
bookname.appendChild(doc.createTextNode(name));
newBook.appendChild(bookname);
//book author
Element bookAuthor = doc.createElement("bookAuthor");
bookAuthor.appendChild(doc.createTextNode(author));
newBook.appendChild(bookAuthor);
//book year
Element bookYear = doc.createElement("bookYear");
bookYear.appendChild(doc.createTextNode(String.valueOf(year)));
newBook.appendChild(bookYear);
//book available
Element bookAvail = doc.createElement("bookAvailable");
bookAvail.appendChild(doc.createTextNode(String.valueOf(free)));
newBook.appendChild(bookAvail);
nList.appendChild(newBook);
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
//initialize StreamResult with File object to save to file
StreamResult result = new StreamResult(new File("Test/Books.xml"));
DOMSource source = new DOMSource(doc);
transformer.transform(source, result);
System.out.println("DONE");

updated xml data not updated in the xml file

i have made a method for updating my xml in the xml file by a using a GUI..
but when I update it everything seem to be working fine and the console is printing out the correct things.
But when I open the xml file and press refrah nothing is updated.
What is my problem?
public void updateObjType(String newTxt, int x) throws ParserConfigurationException, SAXException, IOException, XPathExpressionException {
System.out.println("String value : " + newTxt);
System.out.println("Index value : " + x);
DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = builderFactory.newDocumentBuilder();
Document xmlDocument = builder.parse("xmlFiles/CoreDatamodel.xml");
XPath xPath = XPathFactory.newInstance().newXPath();
// Go thru the Object_types in the XML file and get item x.
NodeList nodeList = (NodeList) xPath.compile("//OBJECT_TYPE/text()")
.evaluate(xmlDocument, XPathConstants.NODESET);
// Set new NodeValue
nodeList.item(x).setNodeValue(newTxt);
String value = nodeList.item(x).getTextContent();
System.out.println(value);
}
this is the output from the console :
Original data : IF150Data
Incoming String value : Data
Index value : 4
updated data : Data

I solved it by using a transformer.
Full solution :
// Update the object type name from the object type list.
public void updateObjType(String newTxt, int x)
throws ParserConfigurationException, SAXException, IOException,
XPathExpressionException {
File file = new File("xmlFiles/CoreDatamodel.xml");
System.out.println("Incoming String value : " + newTxt);
System.out.println("Index value : " + x);
DocumentBuilderFactory builderFactory = DocumentBuilderFactory
.newInstance();
DocumentBuilder builder = builderFactory.newDocumentBuilder();
Document xmlDocument = builder.parse(file);
XPath xPath = XPathFactory.newInstance().newXPath();
NodeList nodeList = (NodeList) xPath.compile("//OBJECT_TYPE/text()")
.evaluate(xmlDocument, XPathConstants.NODESET);
// Set new NodeValue
nodeList.item(x).setNodeValue(newTxt);
// Save the new updates
try {
save(file, xmlDocument);
} catch (Exception e) {
e.printStackTrace();
}
}
And then the method I added :
public void save(File file, Document doc) throws Exception {
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
StringWriter writer = new StringWriter();
StreamResult result = new StreamResult(writer);
DOMSource source = new DOMSource(doc);
transformer.transform(source, result);
String s = writer.toString();
System.out.println(s);
FileWriter fileWriter = new FileWriter(file);
BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);
bufferedWriter.write(s);
bufferedWriter.flush();
bufferedWriter.close();
}

How to set UTF-16 encoding format for Xml?

I am in need to create xml as a string to pass to server. I have managed to convert the data into xml but the encoding format set to utf-8 as default. What i need is i want to set it as utf-16 format. But i haven't got any idea of setting it.
private void XmlCreation(int size,List<DataItem> item) throws ParserConfigurationException, TransformerException
{
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.newDocument();
Element rootElement = document.createElement("ArrayOfDataItem");
document.appendChild(rootElement);
for (DataItem in: item)
{
Element subroot = document.createElement("DataItem");
rootElement.appendChild(subroot);
Element em = document.createElement(in.getKey());
em.appendChild(document.createTextNode(in.getValue()));
subroot.appendChild(em);
}
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
java.io.StringWriter sw = new java.io.StringWriter();
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(System.out);
transformer.transform(source, result);
String xml = sw.toString();
System.out.println(xml);
}
}
Thanks guys

I haven't tested, but that should do the trick:
transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-16");

This article might help you. Basically, you call setOutputProperty with OutputKeys.ENCODING as key and the desired encoding ("UTF-16") as value.

Get full xml text from Node instance

I have read XML file in Java with such code:
File file = new File("file.xml");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(file);
NodeList nodeLst = doc.getElementsByTagName("record");
for (int i = 0; i < nodeLst.getLength(); i++) {
Node node = nodeLst.item(i);
...
}
So, how I can get full xml content from node instance? (including all tags, attributes etc.)
Thanks.

Check out this other answer from stackoverflow.
You would use a DOMSource (instead of the StreamSource), and pass your node in the constructor.
Then you can transform the node into a String.
Quick sample:
public class NodeToString {
public static void main(String[] args) throws TransformerException, ParserConfigurationException, SAXException, IOException {
// just to get access to a Node
String fakeXml = "<!-- Document comment -->\n <aaa>\n\n<bbb/> \n<ccc/></aaa>";
DocumentBuilder docBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = docBuilder.parse(new InputSource(new StringReader(fakeXml)));
Node node = doc.getDocumentElement();
// test the method
System.out.println(node2String(node));
}
static String node2String(Node node) throws TransformerFactoryConfigurationError, TransformerException {
// you may prefer to use single instances of Transformer, and
// StringWriter rather than create each time. That would be up to your
// judgement and whether your app is single threaded etc
StreamResult xmlOutput = new StreamResult(new StringWriter());
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
transformer.transform(new DOMSource(node), xmlOutput);
return xmlOutput.getWriter().toString();
}
}
