Can you provide example of the file that you wish to process? Also, you mention Java in the title, is this what you are looking to implement a solution with? Can you provide some more info on the context of what you are trying to do? i.e. a web app, a console app, one off, etc? Also, is this part of a larger solution of just something standalone?

I do not have to use Java to split file, it can be any tool accessible in Windows, I do have C++. The xml parser is in java(web app), but it will not load because of multiple roots. So I have to split into multiple files based on each root. Then the parser can pick up the file and process. I cannot change parsing code, or the xml structure. I cannot ask vendor to give me multiple files, so I am stuck with splitting the file. Attached is an example with multiple roots. The  loader of portion of java web application picks up the file.

Ok, so your options are fairly limited then. The problem being that the file is not a valid XML file, so no parsers are ever going to touch it. You can either :-

  • Treat it like a simple text file, reading it in and just start a new file everytime you encounter the line with </GamerProfile>   (and hope that that tag never appears nested deeper in the document, i.e. it can cause other issues)
  • Modify the file, either manually or on the fly in the code, to add a top level element that covers all the GamerProfile elements, and then you would be able to write a parser that reads the (now) well-formed XML and write out individual GamerProfile elements to separate files

Unfortunately, I don't know enough C++ these days to help you further (only Java) but this should at least get you thinking in the right direction.
