I have an xml file which I use to send updates from one server to another. To be able to test the bandwidth and number of transactions I would like to create 3000 copies of the xml template. The file name of the template is CR-0001-AAA.xml I would like to change the file name automatically to CR-0002-AAB.xml etc. Additionally I need to be able to edit some tags within the xml e.g. CD to SC Does anyone have any suggestions of software that could do this?
