String replacestr = contactArray.get(i).toString();
                                //Now parse the xml according to your Choice
parseContact("<CONTACT>" + replacestr + "</CONTACT>",context);
}
contactArray.clear();
}


private static void Retrieve_Contact_Tag(String xmlContent) {
Pattern regex = Pattern.compile("<CONTACT>(.*?)</CONTACT>",
Pattern.DOTALL);
Matcher matcher = regex.matcher(xmlContent);
// Pattern regex2 = Pattern.compile("<([^<>]+)>([^<>]+)</\\1>");
if (matcher.find()) {
