I have xml:

<Info>

    <info_1/>

    <info_2/>

    <info_3>

        <i ID="1"/>

        <i ID="2"/>

        <i ID="3"/>

    </info_3>

    <info_4>

    </indo_4>

</Info>  

I need to delete a specific node in info_3, for example a node in which ID = 1, how can I do this?

I tried to do this, but log shows before and after length = 3 :

DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();

DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();

Document doc = dBuilder.parse(new InputSource(new StringReader(bb)));

doc.getDocumentElement().normalize();  



NodeList nList = doc.getElementsByTagName("i");  

Log.e("LOG", "nList.getLength() = " + nList.getLength());

Node node=nList.item(1);  

node.getParentNode().removeChild(node);  

Log.e("LOG", "nList.getLength() = " + nList.getLength());

Solution that helped me:

DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();

DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();

Document doc = dBuilder.parse(new InputSource(new StringReader(bb)));

doc.getDocumentElement().normalize();  



NodeList nList = doc.getElementsByTagName("i");  

Log.e("LOG", "nList.getLength() = " + nList.getLength());

Set<Element> targetElements = new HashSet<>();

for (int i = 0; i < nList_Loan_guarantor.getLength(); i++) {

  Element e = (Element)nList_Loan_guarantor.item(i);

  if ("10938".equals(e.getAttribute("ID"))) {

  targetElements.add(e);

  }

}



for (Element e: targetElements) {

   e.getParentNode().removeChild(e);

   }



doc.getDocumentElement().normalize();

NodeList nList_2 = doc.getElementsByTagName("i"); 

Log.e("LOG", "nList.getLength() = " + nList.getLength());
