I want to retrieve modules from “modules” tag in an array, and the array must contain sub tags for each module. Please suggest some solution.

Answer 1

you can do using node List

Document document = null;
NodeList nodeList = null;
Node node = null;

nodeList = document.getElementsByTagName("modules").item(0).getChildNodes();
HashMap <String,Object> localParameterMap  = new HashMap<String,Object>();

for(int i=0; i<nodeList.getLength(); i++){
    node = nodeList.item(i);
    if(node.getNodeName().equals("Calls")){
        Collection objCollection = readAttributeList(node);
        localParameterMap.put(ATTRIBUTE_LIST, objCollection);
    }
}
