Remove a child of root of XML using java
- by Sachin Mhetre
This is my xml file.
- <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>
I want to remove node with name 'Active wavwform Status'. How can I reomve that particular node from xml.
The code I have written is below.
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...");
}
}
