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);

Casting JDom 1.1.3 Element to Document without DocumentBuilderFactory or DocumentBuilder

I need to find the easier and the efficient way to convert a JDOM element (with all it's tailoring nodes) to a Document. ownerDocument( ) won't work as this is version JDOM 1.
Moreover, org.jdom.IllegalAddException: The Content already has an existing parent "root" exception occurs when using the following code.
DocumentBuilderFactory dbFac = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFac.newDocumentBuilder();
Document doc = null;
Element elementInfo = getElementFromDB();
doc = new Document(elementInfo);
XMLOutputter xmlOutput = new XMLOutputter();
byte[] byteInfo= xmlOutput.outputString(elementInfo).getBytes("UTF-8");
String stringInfo = new String(byteInfo);
doc = dBuilder.parse(stringInfo);

I think you have to use the following method of the element.
Document doc = <element>.getDocument();
Refer the API documentation It says
Return this parent's owning document or null if the branch containing this parent is currently not attached to a document.

JDOM content can only have one parent at a time, and you have to detatch it from one parent before you can attach it to another. This code:
Document doc = null;
Element elementInfo = getElementFromDB();
doc = new Document(elementInfo);
if that code is failing, it is because the getElementFromDB() method is returning an Element that is part of some other structure. You need to 'detach' it:
Element elementInfo = getElementFromDB();
elementInfo.detach();
Document doc = new Document(elementInfo);
OK, that solves the IllegalAddException
On the other hand, if you just want to get the document node containing the element, JDOM 1.1.3 allows you to do that with getDocument:
Document doc = elementInfo.getDocument();
Note that the doc may be null.
To get the top most element available, try:
Element top = elementInfo;
while (top.getParentElement() != null) {
top = top.getParentElement();
}
In your case, your elementInfo you get from the DB is a child of an element called 'root', something like:
<root>
<elementInfo> ........ </elementInfo>
</root>
That is why you get the message you do, with the word "root" in it:
The Content already has an existing parent "root"

Parsing a SOAP response is returning null

String response = "<?xml version='1.0'?><soap:Envelope xmlns:soap='http://www.w3.org/2003/05/soap-envelope'><soap:Body><exch:Response xmlns:exch='http://applicant.ffe.org/exchange/1.0'>...</exch:Response></soap:Body></soap:Envelope>";
DocumentBuilderFactory dbf = null;
DocumentBuilder db = null;
org.w3c.dom.Document document = null;
try {
dbf = DocumentBuilderFactory.newInstance();
db = dbf.newDocumentBuilder();
InputSource is = new InputSource(new ByteArrayInputStream(response.getBytes("UTF-8")));
document = db.parse(is);
} catch(ParserConfigurationException e){}
catch(SAXException e){}
document is returning with null. I have tried different ways to pass to InputSource, but document is still returning null. Any idea why this might be happening?

I just tried i could get the elements name and values .
try {
dbf = DocumentBuilderFactory.newInstance();
db = dbf.newDocumentBuilder();
InputSource is = new InputSource(new ByteArrayInputStream(response.getBytes("UTF-8")));
document = db.parse(is);
System.out.println(document);//here we get null;
System.out.println(document.getNodeName());//here we get document;
for(int i =0 ; i<document.getChildNodes().getLength();i++)
System.out.println(document.getChildNodes().item(i).getChildNodes().item(i).getNodeName());
}
Output :
[#document: null]
document
soap:Body
To parse SOAPResponse we can javax.xml.soap.* it may take u to traverse the object xml tree. Anyway we may need parse the elements from SOAP Body . we could parse these very simple manner using DOM format .

Delete TextContents of XML element before appending text

I am appending text to XML element iteratively like the following
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setValidating(false);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new FileInputStream(new File("./myXML.xml")));
Element element = doc.getDocumentElement();
NodeList node1 = doc.getElementsByTagName("name");
Element fn= (Element) node1.item(0);
Text text = doc.createTextNode(Content);
fn.appendChild(text);
printtoXML(doc);
My printXML method is updating xml by using TransformerFactory
fn.setTextContent() method does not work here,Because in every iteration it setting old text to new text.
I want to append Text iteratively, and in my next execution i want to delete old text contents of the particular element and append it again.
I have to execute the program many times for my testing and i don't want to append the same text again and again....
Could you please help me to solve this problem..

this might work
Text text;
void callsomefunctionthousendtimes(){
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setValidating(false);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new FileInputStream(new File("./myXML.xml")));
text = doc.createTextNode("");
Element element = doc.getDocumentElement();
NodeList node1 = doc.getElementsByTagName("name");
Element fn= (Element) node1.item(0);
//TODO call your functionName(content) 1000 times here
fn.appendChild(text);
printtoXML(doc);
}
void functionName(String content){
text = text.replaceWholeText(text.getWholeText() + content);
}
added bonusus, only load the doc in once

Getting value of child node from XML in java

My xml file looks like this
<InNetworkCostSharing>
<FamilyAnnualDeductibleAmount>
<Amount>6000</Amount>
</FamilyAnnualDeductibleAmount>
<IndividualAnnualDeductibleAmount>
<NotApplicable>Not Applicable</NotApplicable>
</IndividualAnnualDeductibleAmount>
<PCPCopayAmount>
<CoveredAmount>0</CoveredAmount>
</PCPCopayAmount>
<CoinsuranceRate>
<CoveredPercent>0</CoveredPercent>
</CoinsuranceRate>
<FamilyAnnualOOPLimitAmount>
<Amount>6000</Amount>
</FamilyAnnualOOPLimitAmount>
<IndividualAnnualOOPLimitAmount>
<NotApplicable>Not Applicable</NotApplicable>
</IndividualAnnualOOPLimitAmount>
</InNetworkCostSharing>
I am trying to get Amount value from <FamilyAnnualDeductibleAmount> and also from <FamilyAnnualOOPLimitAmount>. How do i get those values in java?

You may use two XPath queries /InNetworkCostSharing/FamilyAnnualDeductibleAmount and InNetworkCostSharing/FamilyAnnualOOPLimitAmount or just get the node InNetworkCostSharing and retrieve the values of its two direct children.
Solution using XPath:
// load the XML as String into a DOM Document object
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
ByteArrayInputStream bis = new ByteArrayInputStream("YOUR XML".getBytes());
Document doc = docBuilder.parse(bis);
// XPath to retrieve the content of the <FamilyAnnualDeductibleAmount> tag
XPath xpath = XPathFactory.newInstance().newXPath();
XPathExpression expr = xpath.compile("/InNetworkCostSharing/FamilyAnnualDeductibleAmount/text()");
String familyAnnualDeductibleAmount = (String)expr.evaluate(doc, XPathConstants.STRING);

StAX based solution:
XMLInputFactory f = XMLInputFactory.newInstance();
XMLStreamReader rdr = f.createXMLStreamReader(new FileReader("test.xml"));
while (rdr.hasNext()) {
if (rdr.next() == XMLStreamConstants.START_ELEMENT) {
if (rdr.getLocalName().equals("FamilyAnnualDeductibleAmount")) {
rdr.nextTag();
int familyAnnualDeductibleAmount = Integer.parseInt(rdr.getElementText());
System.out.println("familyAnnualDeductibleAmount = " + familyAnnualDeductibleAmount);
} else if (rdr.getLocalName().equals("FamilyAnnualOOPLimitAmount")) {
rdr.nextTag();
int familyAnnualOOPLimitAmount = Integer.parseInt(rdr.getElementText());
System.out.println("FamilyAnnualOOPLimitAmount = " + familyAnnualOOPLimitAmount);
}
}
}
rdr.close();
Note that StAX is especially good for cases like yours, it skips all unnecessary elements reading only the ones you need

Try something like this(use getElementsByTagName to get the parent nodes and then get the value be reaching out to child node):
File xmlFile = new File("NetworkCost.xml");
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(xmlFile );
doc.getDocumentElement().normalize();
NodeList nList = doc.getElementsByTagName("FamilyAnnualDeductibleAmount");
String familyDedAmount = nList.item(0).getChildNodes().item(0).getTextContent();
nList = doc.getElementsByTagName("FamilyAnnualOOPLimitAmount");
String familyAnnualAmount =
nList.item(0).getChildNodes().item(0).getTextContent();
