I am storing xml data in a string into user preferences. I want to create hashmap from this xml string. please help me; here is my xml string;

 String data = " <modules> <Calls> <access>89</access> <delete>90</delete> <edit>90</edit> <export>90</export> <import>90</import> <list>90</list> <view>90</view> </Calls> <Cases> <access>89</access> <delete>90</delete> <edit>90</edit> <export>90</export> <import>90</import> <list>90</list> <view>90</view> </Cases> <CFM_CoBuyer> <access>89</access> <delete>90</delete> <edit>90</edit> <export>90</export> <import>90</import> <list>90</list> <view>90</view> </CFM_CoBuyer> <Contacts> <access>89</access> <delete>-99</delete> <edit>90</edit> <export>90</export> <import>90</import> <list>90</list> <view>90</view> </Contacts> <Inv_Inventory> <access>89</access> <delete>90</delete> <edit>90</edit> <export>90</export> <import>90</import> <list>90</list> <view>90</view> </Inv_Inventory> <Meetings> <access>89</access> <delete>90</delete> <edit>90</edit> <export>90</export> <import>90</import> <list>90</list> <view>90</view> </Meetings> <Notes> <access>89</access> <delete>90</delete> <edit>90</edit> <export>90</export> <import>90</import> <list>90</list> <view>90</view> </Notes> <Opportunities> <access>89</access> <delete>-99</delete> <edit>90</edit> <export>-99</export> <import>-99</import> <list>80</list> <view>90</view> </Opportunities> <Tasks> <access>89</access> <delete>90</delete> <edit>90</edit> <export>90</export> <import>90</import> <list>90</list> <view>90</view> </Tasks> <Trd_TradeIns> <access>89</access> <delete>90</delete> <edit>90</edit> <export>90</export> <import>90</import> <list>90</list> <view>90</view> </Trd_TradeIns> </modules> ";

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.

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); } }

Thank you man for the reply @Riddhish.Chaudhari. Yes NodeList was the actual solution to my requirement, Here is how I solved it..

public static HashMap<String, Role> roles = null; public static String user_roles = null;

then I implemented following function;

public static void parseRoles(){ roles = new HashMap<String, Role>(); user_roles = data; // my xml string try { Document dom = getXMLDocument(user_roles); NodeList modules = dom.getDocumentElement().getChildNodes(); for (int i=0; i<modules.getLength(); i++){ Role role = new Role(); Node module = modules.item(i); String moduleName = module.getNodeName(); NodeList accesses = module.getChildNodes(); for (int j=0; j<accesses.getLength(); j++){ Node access = accesses.item(j); String name = access.getNodeName(); int accessValue = -1; try{ accessValue = Integer.parseInt(access.getFirstChild().getNodeValue().trim()); }catch (Exception e) { AlertHelper.logError(e.getClass().getCanonicalName(), e.getMessage()); } if(accessValue != -1){ if(name.equalsIgnoreCase("access")){ role.access = accessValue; }else if(name.equalsIgnoreCase("view")){ role.view = accessValue; }else if(name.equalsIgnoreCase("list")){ role.list = accessValue; }else if(name.equalsIgnoreCase("edit")){ role.edit = accessValue; }else if(name.equalsIgnoreCase("delete")){ role.delete = accessValue; } } } roles.put(moduleName.toLowerCase(), role); } } catch (Exception e) { roles = null; AlertHelper.logError(e.getClass().getCanonicalName(), e.getMessage()); } }

I added following class in my project project, which is storing data from xml in Role() object in the above function;

public class Role { public int access = 89; public int view = 90; public int list = 90; public int edit = 90; public int delete = 90; }

Now whenever I need to get data I can use following way;

Suppose I want to get elements from Calls module, then using hashmap roles;

int access = roles.get("Calls").access; int view = roles.get("Calls").view; int list = roles.get("Calls").list; int edit = roles.get("Calls").edit; int delete = roles.get("Calls").delete;
