    <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

这很适合我

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

你的主要问题在于

final String DIV_UNDER_ROOT = "/*/aoi"; 

这是一个XPath表达式，根据匹配“的任何节点2级根，它具有aoi的本地名称并且没有名称空间“。这不是你想要的。

你想匹配的是两层深的一个节点，其名称空间是由“苍井空”（这意味着它属于“http://www.aointl.com/20160331”命名空间），而其本地名称是“OtherIncomeAndExpensePolicyTextBlock”别名的任何内容。 XPath中使用Java

匹配的命名空间是安静的繁琐（见XPath with namespace in Java和How to query XML using namespaces in Java with XPath?），但长话短说，你可以尝试这种方式来代替：

final String DIV_UNDER_ROOT = "//*[local-name()='OtherIncomeAndExpensePolicyTextBlock' and namespace-uri()='http://www.aointl.com/20160331']/*"; 

这只会工作，如果你的DocumentBuilderFactory由命名空间感知，所以你应该像这样上述配置它确保：

DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance(); 
dbFactory.setNamespaceAware(true);
