I am working with a java program that exports data from database as an xml file. I would like to know wheter there is a "ready to use" program, which can manipulate the data in the xml file, so I do not need to develop it myself. The data and structure of the xml file is flexible depending on the fields the user wants to export. Is there a java application that reads any xml file and gives the opportunity to work with it directly with little or no configuration.
Sure, there's lots of them... if we remove your requirement that they be Java applications. (Why is that a requirement anyway?) Stylus Studio comes to mind, and XMLSpy from Altova, and I'm sure there's lots more.

In terms of your question, it depends on what you mean by ''work." XML is a meta-language for creating markup languages, so there are thousands of them. Each one is different. There is no single tool that can address data processing requirements for all of the existing XML-based languages and those to be created in the future. Basically, the only tools that work with all XML-based languages are editors, e.g. XMLSpy, XML X-Ray, etc., and XML parsers, e.g. Xerces, Crimson, etc.
Also, Java is a name so the first letter should be in upper-case and XML is an acronym so each letter should be in upper-case.
