Cheers for any help, and code (pseudo or otherwise) would be great. Or just a yes or no you can/can't do that would be a start.
its possible, but you'll have to write a 'tar' filter to allow you to extract the XML file, (Iostreams should already deal with the gzip). If you only need to pick out a single file from an input stream, it shouldn't be too hard to deal with. You'll 'just' have to parse the tar headers till you match the file(s) you want, then pass them as the output of your filter onto the next stage, which can be your XML decoding/whatever. dealing with the multiple files though depends on if your program needs them 'in order' in some way, and if that order is the one the external program writes the tar archive in, otherwise you'll want to deal with rewindable stream or do a multiple pass algorithm or something, but thats more an application issue.
