    My message was mainly about XML, for which it is easy.
    For non-XML, you need some other way of knowing the file format. The
    example that originally came up in this thread was

    /etc/passwd/[username]

    In this case, the passwd file has a known format.
    Other file types, like LaTex, html, jpeg also have (at least partially)
    known formats. Some selection should be possible even for unknown
    formats (e.g. byte range, line-range). There could also be some way of
    specifying a new format but I don't know how to do this well. You could
    give names (like filenames) to parts of files.
    But I think the first step would be to concentrate on XML, and worry
    about the rest later. Peter
