如何在XML标记替换值时，节点在使用JAVA

Question

我需要更换sEmployee和sWUnumber值多值（突出表现在上面黄色）

到目前为止，我所能做的就是替换节点值和其他属性。但是，当在标签。我似乎无法取代sEmployee和SWUnumber。我认为这些元素不是属性？

继承人到目前为止我做了什么。

DocumentBuilderFactory docFactory = DocumentBuilderFactory 
      .newInstance(); 
    DocumentBuilder docBuilder = docFactory.newDocumentBuilder(); 
    Document doc = docBuilder.parse(Constant.Path_OldXmlFile); 

    // Get Employee ID, I'm getting my values in excel data so don't mind this 
    String sNewEmployeeID = ExcelUtils.getCellData(iTestCaseRow, 
      Constant.Personnel_NewEmployeeID); 

    // Get Work Unit Number, I'm getting my values in excel data so don't mind this 
    String sWorkUnitNumber = ExcelUtils.getCellData(iTestCaseRow, 
      Constant.Personnel_WorkUnit);

您可以使用XPath查询文档的节点后，您和替换它的文本内容，例如

try { 
    // Load the document 
    DocumentBuilderFactory f = DocumentBuilderFactory.newInstance(); 
    DocumentBuilder b = f.newDocumentBuilder(); 
    Document original = b.parse(...); 

    // Surgically locate the node you're after 
    String expression = "/SyncPersonnel/ApplicationArea/BODID"; 
    XPath xPath = XPathFactory.newInstance().newXPath(); 
    Node node = (Node) xPath.compile(expression).evaluate(original, XPathConstants.NODE); 
    // Get the nodes current text content 
    String value = node.getTextContent(); 
    System.out.println(value); 

    // Replace the values 
    value = value.replace("sEmployee", "BananaMan").replace("sWUnumber", "007"); 
    // Set the text content with the new value 
    node.setTextContent(value); 

    // Save the new document 
    try (ByteArrayOutputStream os = new ByteArrayOutputStream()) { 

     Transformer tf = TransformerFactory.newInstance().newTransformer(); 
     tf.setOutputProperty(OutputKeys.INDENT, "yes"); 
     tf.setOutputProperty(OutputKeys.METHOD, "xml"); 
     tf.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4"); 

     DOMSource domSource = new DOMSource(original); 
     StreamResult sr = new StreamResult(os); 
     tf.transform(domSource, sr); 

     String text = new String(os.toByteArray()); 
     System.out.println(text); 

    } catch (TransformerException ex) { 
     ex.printStackTrace(); 
    } 

} catch (ParserConfigurationException | SAXException | IOException | XPathExpressionException | DOMException exp) { 
    exp.printStackTrace(); 
} 

使用...

<?xml version="1.0" encoding="UTF-8"?> 
<SyncPersonnel> 
    <ApplicationArea> 
    <BODID>...-nid:LSAPPS:3004::sEmployee:0?Personnel&amp;verb=Sync&amp;workunit=sWUnumber</BODID> 
    </ApplicationArea> 
</SyncPersonnel> 

将上面的代码生成

<?xml version="1.0" encoding="UTF-8" standalone="no"?> 
<SyncPersonnel> 
    <ApplicationArea> 
    <BODID>...-nid:LSAPPS:3004::BananaMan:0?Personnel&amp;verb=Sync&amp;workunit=007</BODID> 
    </ApplicationArea> 
</SyncPersonnel>
