这是我的xml文件。

- <deviceparameters>
       - <parameter componenttype="TextBox">
         <name>Operating Type</name> 
         <oid>1.3.6.1.4.1.31163.5.1.1</oid>  
         <writable>true</writable> 
         <description>The operating type defines which waveform type is used. This configuration takes several seconds to execute</description> 
       - <paramvalues type="Integer">
            <value default="No">123</value> 
         </paramvalues>
         </parameter>

       - <parameter componenttype="TextBox">
         <name>Active Waveform Status</name> 
         <oid>1.3.6.1.4.1.31163.5.1.2</oid> 
         <writable>false</writable> 
         <description>Show the status of the waveform configured by operatingType</description> 
       - <paramvalues type="String">
            <value default="yes">Active</value> 
      </paramvalues>
      </parameter>
    </deviceparameters>

我想删除名称为“ Active wavwform Status”的节点。如何从xml中删除该特定节点。

我写的代码如下。

rootElement = doc.getDocumentElement();
NodeList nList = doc.getElementsByTagName("parameter");
String nodeName = TF_name.getText();


System.out.println(""+nList.getLength());

for (int temp = 0; temp < nList.getLength();temp++)                
{
    Node nNode =  nList.item(temp);    
    Element eElement = (Element) nNode;
    String upname1 = getTagValue("name", eElement);

    if(upname1.equals(nodeName))
    {
        System.out.println("Parent:   "+nNode.getParentNode().getNodeName());
        System.out.println("nodename: "+nNode.getNodeName());
        System.out.println("rmoving ....");

        rootElement.removeChild(nNode);

        System.out.println("removed..."); 
    }                   
}
