    <aoi:OtherIncomeAndExpensePolicyTextBlock contextRef="FD2016Q4YTD" id="Fact-F51C7616E17E5B8B0B770D410BBF5A3E">
    <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>
    </aoi:OtherIncomeAndExpensePolicyTextBlock>
    </xbrli:xbrl>

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();
        }

Answer 1

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());
}

Answer 2

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);
