Problems with and tags while reading the xml file

Question

Hi
I am using the xml files in my project. The project uses Tomcat, JMS. The project is divided into some components which communicate with each oher thru JMS. The component for which I am responsible gets a dcoument object from the JMS which is a processed xml of the following format (the processing is done by the DBMS_XMLGEN package of oracle)
<?xml version="1.0" encoding="UTF-8"?>
<root>
<filename>157_1000000001</filename>
<querydata>
<tabdata>
<tabinfo>Tab-id3</tabinfo>
<queryset>
<query name="Fax">
select a.ARLN_NAME,d.TICKETED_ORIGIN,d.TICKETED_DESTINATION, d.ENDORSEMENTS,to_char(d.DATE_OF_ISSUE,'DDMONYY') as DATE_OF_ISSUE ,d.EXCHANGE_DOC_TYPE,
               d.PASSENGER_NAME,d.ORIG_ISS_AIRLINE,d.ORIG_DOC_NO,d.ORIG_PLACE_OF_ISSUE,
               to_char(d.ORIG_DATE_OF_ISSUE,'DDMONYY'),d.ORIG_ISSUE_AGENT,d.CUR_OF_SALE,d.GROSS_FARE,d.EQUIV_CUR_OF_SALE,d.EQUIV_FARE,
               d.PANDA_DEAL_CODE,d.ISI,d.reporting_date
               from airline_master a,ticket_main d,ticket_conj e where d.doc_no = e.doc_no and d.iss_airline = e.iss_airline
               and e.conj_doc_no = (select DOC_NO from TICKET_CONJ where CONJ_DOC_NO = 1000000001 and ISS_AIRLINE = 157)
               and e.ISS_AIRLINE = 157 and d.iss_airline = a.ARLN_NUM_CODE
</query>
</queryset>
</tabdata>
</querydata>
the function on my side is like this
private void processMessage(ObjectMessage objmessage)
     Document XMLreqObject = (Document) objmessage.getObject();
     Element root = XMLreqObject.getRootElement();                
     String resultFilename = root.getChildText("filename");
     Element tabSet = root.getChild("querydata");//doesnt work
     ArrayList tabSetlist = new ArrayList(tabSet.getChildren ("tabdata"));//doesnt work
The code commented with "doesnt work", is not working. What must be the problem ?
Thanks in Advance

Answer 1

Okay. Your original example XML didn't include < or > which was rather confusing if that particular feature was supposed to be the cause of the problem. Also calling them "tags" was rather confusing since "tags" is the term for the things that come at the beginning and of an element, like this:<data>...</data>Anyway, I assume your theory is that documents that don't have < in a text element process correctly and documents that do have < in a text element get "stuck" in the parser? Well, from your original description the process appears to be:
1. Create XML
2. Parse it into a Document
3. Send the Document via JMS
4. Receive the Document via JMS
5. Process it.
And it's step 4 that is "stuck"? That would be my guess based on the code you posted.
