Hi
Is there any AXIOM expert in this group who can answer this question? I sent this question to the appropriate group "[EMAIL PROTECTED]", unfortunately this group is not quite active as I've not been getting any emails from this group for past few days. Thanks Chandru Ganesan -----Original Message----- From: Ganesan, Chandru Sent: Tuesday, December 18, 2007 5:13 PM To: [email protected] Subject: StAX parsing of XML file using AXIOM API Hi I'm a newbie to Apache Axis2. I have few questions on AXIOM (StAX)API. Since I didn't get any answers to my original post to '[EMAIL PROTECTED]' mailing list, I'm posting to this group hoping for answers/guidance. I'd like to parse a huge file without building complete object model (linked list of OM elements) in memory i.e., I don't want the effect of going back in the inputstream and reading elements. I have following file structure: <Soap-Envelope> <Soap-Header> .... </Soap-Header> <Soap-Body> <batch-request> <addRequest> ...... </addRequest> <addRequest> <!-- thousands of addRequests here. I'd like to parse each addRequest one at a time without preserving OM elements of previous and subsequent elements > <addRequest> </batch-request> </Soap-Body> </Soap-Envelope> I have following questions: 1. During my analysis, I found out that whenever I use an Iterator, as in the code snippet below, to get a childElement using iterator.next(), AXIOM builds a link list of all child elements (OM Element) similar to DOM tree i.e., whole document is parsed and OM elements are created in memory. ..... QName qName = new QName("http://schemas.xmlsoap.org/soap/envelope";, "Body", "soap"); Iterator itr = soapEnvelope.getChildrenWithName(qName); while(itr.hasNext()) { OMElement element = (OMElement) itr.next(); } However, when I used StAXSOAPModelBuilder to extract SOAPEnvelope, SOAPElement, SOAPBody it is able to build without parsing the whole file. Following code does not build complete object model: StAXSOAPModelBuilder builder = new StAXSOAPModelBuilder(parser, "http://schemas.xmlsoap.org/soap/envelope/";); QName soapHeaderQName = new QName("http://schemas.xmlsoap.org/soap/envelope/";, "Header"); SOAPEnvelope envelope = (SOAPEnvelope) builder.getDocumentElement(); SOAPHeader soapHeader = envelope.getHeader(); QName soapBodyQName = new QName("http://schemas.xmlsoap.org/soap/envelope/";, "Body"); SOAPBody soapBody = envelope.getBody(); OMElement elem = soapBody.getFirstElement(); 2. What is the best way to parse above SOAP file one addRequest at a time without building OM elements for previous/subsequent addRequests? I cannot use SOAP builder as I have some XML files which are not SOAP based.
