Hi,
1) You need to use JDOM parser.
2) The code for parsing XML using JDOM parser is readily available if you search on google.
3) You will have to check the attribute during every parsing and then if attribute is quantity you can fetch the corresponding tags.
4) Something similar to this:
org.jdom.Document document = parser.build(file);
                org.jdom.Element rootElement = document.getRootElement();
                org.jdom.Element childElement = rootElement.getChild("file");
                Element xmlElement = childElement.getChild("item");
                if (xmlElement != null) {
                    List itemElementsList = xmlElement.getChildren("item1");
                    if (itemElementsList != null) {
                        Iterator iterator3 = itemElementsList.iterator();
                        while (iterator3.hasNext()) {
                            //For each group get quantity
                            Element itemElement = (Element) iterator3.next();
                            List quantityElementsList =
                                    itemElement.getChildren("quantity");
                            if (quantityElementsList != null) {
                                Iterator iterator2 =
                                        quantityElementsList.iterator();
                                while (iterator2.hasNext()) {
// Your code                                                                               
You might need to make some changes as per your rquirement. Just use this sample to understand how you need to parse the xml
Hope it helps.
Regards.
