避免将XML名称空间添加到输出消息

我试图在现有XML中添加一个元素。改造后，我得到了xmlns=""添加元素，我不需要。避免将XML名称空间添加到输出消息

原始XML：

<Message version='010' release='006' 
     xsi:schemaLocation='http://www.ncpdp.org/schema/SCRIPT SS_SCRIPT_XML_10_6MU.xsd' 
     xmlns='http://www.ncpdp.org/schema/SCRIPT' 
     xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'> 

    <Header> ... </Header> 
    <Body> 
     <New> ... 
      <Medication> 
       ... 
       <StatusCode>NF</StatusCode> 
       <StatusCode>NR</StatusCode> 
      </Medication> 
     </New> 
    </Body> 
</Message>

实际（不需要）输出：

<Message version='010' release='006' 
     xsi:schemaLocation='http://www.ncpdp.org/schema/SCRIPT SS_SCRIPT_XML_10_6MU.xsd' 
     xmlns='http://www.ncpdp.org/schema/SCRIPT' 
     xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'> 

    <Header> ... </Header> 
    <Body> 
     <New> ... 
      <Medication> 
       ... 
       <StatusCode>NF</StatusCode> 
       <StatusCode>NR</StatusCode> 
       <StatusCode xmlns="">SI</StatusCode> 
      </Medication> 
     </New> 
    </Body> 
</Message>

预期输出：

<Message version='010' release='006' 
     xsi:schemaLocation='http://www.ncpdp.org/schema/SCRIPT SS_SCRIPT_XML_10_6MU.xsd' 
     xmlns='http://www.ncpdp.org/schema/SCRIPT' 
     xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'> 

    <Header> ... </Header> 
    <Body> 
     <New> ... 
      <Medication> 
       ... 
       <StatusCode>NF</StatusCode> 
       <StatusCode>NR</StatusCode> 
       <StatusCode>SI</StatusCode> 
      </Medication> 
     </New> 
    </Body> 
</Message>

我做不想在添加的元素<StatusCode>SI</StatusCode>中输入xmlns=""。

Java代码：

private DocumentBuilderFactory getDocumentBuilderFactory() { 
    if (factory == null) { 
     factory = DocumentBuilderFactory.newInstance(); 
     factory.setIgnoringElementContentWhitespace(true); 
     factory.setNamespaceAware(true); 
    } 
    return factory; 
} 

public void addSIElement() throws ParserConfigurationException, SAXException, IOException, TransformerException { 

    Transformer transformer = null; 
    Document doc = getDocumentBuilderFactory().newDocumentBuilder().parse(new InputSource(new StringReader(xmlMsg))); 

    Node list = doc.getElementsByTagName("Medication").item(0); 
    Element el = doc.createElement("StatusCode"); 
    el.setTextContent("SI"); 
    list.appendChild(el); 
    Source source = new DOMSource(doc); 
    StringWriter writer = new StringWriter(); 
    Result newResult = new StreamResult(writer); 
    if (transformer == null) { 
     transformer = TransformerFactory.newInstance().newTransformer(); 
    } 

    transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes"); 
    transformer.setOutputProperty(OutputKeys.INDENT, "yes"); 
    transformer.transform(source, newResult); 

    String outStr = writer.toString(); 
    System.out.println("Final " + outStr); 
}

您在创建一个新的元素没有命名空间，但在你的原始XML的所有元素都属于http://www.ncpdp.org/schema/SCRIPT命名空间。为了正确地添加元素，解析器添加了xmlns=""属性，因此该元素被声明为属于无名称空间。

为了解决这个问题，创建使用org.w3c.dom.Document.createElementNS提供原始文件的命名空间的元素：

Element el = doc.createElementNS("http://www.ncpdp.org/schema/SCRIPT", "StatusCode");
