Parse XML using Java

I need to parse a XML file and append the data into 3 separate files. The tricky bit is the data needs to be rotated before being appended. Program needs to be run from command line as it is going to be scheduled to run automatically every morning. Prefer java but not required. (I can’t write it but I can read it) The file will look like [login to view URL] (file attached) Each day the daily file needs to be converted and appended to three files [login to view URL], [login to view URL] and [login to view URL] The 1/3 of the results should look like [login to view URL] (file attached) ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). * * *This broadcast message was sent to all bidders on Saturday May 12, 2007 11:22:28 AM: The data are in three columns, by area, produced each morning direct from access using VBS. I need the information from each of those columns separated into three different files and rotated from up & down to left to right using the date/time as the left-most column. ## Platform Prefer Java, running in XP
