             <OfficeDepot label="OD" version="7">
                    <word32 label="Zip" value="7220"/>
                    <word32 label="Street" value="1934"/>
                    <word32 label="Type" value="341"/>
                    <word32 label="Count" value="400"/>
                    <word32 label="Open" value="145"/>
               </<OfficeDepot >

How can I extract the value of count in this xml string which is under the parent  officedepot .
In the start tag event I am able to idetify Officedepot as a tag. How do I traverse down and get the  value for count
Thanks for all the help

This is really moving away from SAX towards DOM but you can do it by saving OfficeDepot on a 'stack':

public class SimpleXmlPullApp {

      public static void main(String args[]) throws XmlPullParserException,
                  IOException {
            XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
            XmlPullParser xpp = factory.newPullParser();
            boolean officeDepotIsCurrent = false;

            String input = "<OfficeDepot label=\"OD\" version=\"7\">"
                        + "<word32 label=\"Zip\" value=\"7220\"/>"
                        + "<word32 label=\"Street\" value=\"1934\"/>"
                        + "<word32 label=\"Type\" value=\"341\"/>"
                        + "<word32 label=\"Count\" value=\"400\"/>"
                        + "<word32 label=\"Open\" value=\"145\"/>" + "</OfficeDepot>";
            xpp.setInput(new StringReader(input));
            int eventType = xpp.getEventType();
            String count = null;
            String tagName = null;
            while (count == null && eventType != XmlPullParser.END_DOCUMENT) {
                  if (eventType == XmlPullParser.START_TAG) {
                        tagName = xpp.getName();
                        if ("OfficeDepot".equals(tagName)) {
                              officeDepotIsCurrent = true;
                        else if (officeDepotIsCurrent && "word32".equals(tagName)) {
                              String label = xpp.getAttributeValue(null, "label");
                              if ("Count".equals(label)) {
                                    count = xpp.getAttributeValue(null, "value");
                  else if (officeDepotIsCurrent && eventType == XmlPullParser.END_TAG) {
                        if (tagName.equals("OfficeDepot")) {
                              officeDepotIsCurrent = false;
                  eventType = xpp.next();
            if (count != null) {
                  System.out.printf("count=%s\n", count);
