Digester parsing multiple tags in XML

Question

Hi,
I am using Digester parser to parse a XML which does have multiple tags in it like for example:-
<Customer>
<Customerdetails>
<Customer name="xxx" age="xxx" />
<Customer name="yyy" age="yyy" />
</Customerdetails>
<Messages>
<Success msg="success" active="true"/>
<Failure msg="failure" active="true"/>
</Messages>
</Customer>
Here i am parsing the the customer details using the following code with Digester:-
Digester digester = new Digester();
digester.setValidating(false);
ArrayList<Customer> customerList = new ArrayList<Customer>();
digester.push(customerList);
digester.addObjectCreate("Customer/Customerdetails/Customer", Customer.class);
          String[] attributeNames = new String[] { "name",
                    "age"};
          String[] propertyNames =new String[] { "name",
                    "age"};
          digester.addSetProperties("Customer/Customerdetails/Customer", attributeNames,
                    propertyNames);
          digester.addSetNext("Customer/Customerdetails/Customer", "add");
// parsing for Message success & failure will go here
          try {
               digester.parse(in);
          } catch (Exception e) {
               throw new RuntimeException(e);
          System.out.println("the customerList.size"+customerList.size());
          return customerList;
here it is giving the CustomerList size as "2" , which is correct and i am getting the customer details (name & age) properly, now i need to parse the <Messages> both "Success" and "Failure", that should be done in the same method , when i try to do the same logic for Messages like:-
digester.addObjectCreate("Customer/Messages/Success", Customer.class);
String[] attributeNames = new String[] { "msg",
                    "active"};
          String[] propertyNames =new String[] { "msg",
                    "active"};
          digester.addSetProperties("Customer/Messages/Success", attributeNames,
                    propertyNames);
          digester.addSetNext("CustomerMessages/Success", "add");
i am getting the success message data properly , but the customerdetails data is lost, since i am writing this logic next after the customerdetails.
Now i need the final list (ie) CustomerList to hold all the values that is "Customerdetails", "MessageSuccess" & "MessageFailure" . But i am getting only the values for the last one that is parsed. Is there any way to get all those values in the final list (CustomerList), i am pretty new to Digester, similarly to parse the message failure details, whether we need create another digester.addObjectCreate("Customer/Messages/Failure", Customer.class); to parse it , cant we optimize this through Digester? Please do shed some light into this.
Thanks,
