Dear Wiki user, You have subscribed to a wiki page or wiki category on "Ws Wiki" for change notification.
The following page has been changed by VarunaJayasiri: http://wiki.apache.org/ws/VarunaJayasiri-GSoC2008-expat New page: = Google Summer of Code 2008 â Project proposal = || Project || Integrate expat parser into Axis2/C soap engine || || Student Name || Varuna Jayasiri || || Email || vpjayasiri at gmail dot com || == Synopsis == Axis 2/C currently supports the XML parsers libxml[[FootNote([http://expat.sourceforge.net/ The Expat XML Parser])]] and Guththila[[FootNote([http://www.cse.mrt.ac.lk/~premalwd/Projects/Guththila.html Guththila-Soap Parser])]]. It is possible to plug-in any XML parser to Axis2/C through its parser abstraction layer. I will introduce Expat XML parser to AXIS2/C. Expat is probably the world fastest XML parser and it is a very robust parser. Expat will be plugged into Axis2/C through a wrapper using the XML reader/writer interface of Axiom. == Project == This project will consist of developing a pull layer and a Expat XML writer/reader wrapper for Axiom. Expat is a push parser and Axiom interface is for a pull parser. Therefore a pull layer should be introduced to bridge them. The pull layer should be implemented with internal call-back handlers on top of Expat. The main challenge would be adding a pull interface to Expat without reducing its performance. With the introduction of the functions {{{ XML_StopParser }}} and {{{ XML_ResumeParser }}} it is possible to stop and resume parsing easily enabling pull parsing. These functions had been added specifically for this purpose. However, these functions will become obselete with Expat 3 release[[FootNote([http://expat.sourceforge.net/dev/expat3.html Changes in Expat 3])]]. There are some third party pull layers on Expat; therefore it is possible to examine how they have done it. Expat is also working on a Pull API project and it would be possible to get their ideas on this as well. == Deliverables == 1. Expat read/write wrapper for Axiom. 2. Unit test cases. == Schedule == ==== 1. Analysis and Design ==== Analyze the Expat parser and the interface of the Axiom and design a pull-layer for expat. A great attention will be given for performance of the parser at this stage. -until end of May Deliverables: Design documentation ==== 2. Implementation ==== Implement the pull layer for Expat and the wrapper to bridge it with Axiom. All code will be tested using unit tests. -until mid August Deliverables: A working Expat integration ==== 3. Final Touch ==== Running complete tests with the help of the community and doing final touches to the code and documentations. -until end of August Deliverables: Completed Expat integration with documentation and test data == Biography == Iâve been very enthusiastic about computers from my early ages and I participated in International Olympiad in Informatics 4 times and won a gold medal and 2 silver medals. I also participated at ACM regionalâs in Kanpur[[FootNote([http://www.cse.iitk.ac.in/users/acm/ ACM Regionals Kanpur])]], India with the team which was placed fourth. I was also in the team that developed Sinhala Search â the first Sinhala search engine[[FootNote([http://www.sinhalasearch.com Sinhala Search] - site is currently unavailable due to maintenance :P)]]. I have worked as a SAP developer at MAS Intimates and as a web developer at Paradox Software. I am studying at the Faculty of Engineering, University of Moratuwa, Sri Lanka. I have been blogging for around 1 year â [http://www.xvpj.net Something Different], and I participate in Topcoder[[FootNote([http://www.topcoder.com/tc?module=MemberProfile&cr=21475659 My Topcoder Profile])]] competitions regularly. Although I haven't been involved in open source projects before I have been doing similar projects at my workplaces, and I have about 5 years of experience of programming with C/C++. Therefore, I think I will be able to develop a robust XPath extension for Axiom. == References == [[FootNote]] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
