This is a test script that uses the nsStreamDataSource class to read
|
|
a file from the local file system (using a "file:" URL) and write it
|
|
back. The idea is that the RDF that gets written out should be
|
|
equivalent (but not necessarily identical) to the RDF that was read
|
|
in.
|
|
|
|
Currently, the nsFileSpec stuff is _really_ sensitive to Win32 file
|
|
names: be sure to use a file URL that looks like
|
|
"file://G:/tmp/foo.rdf"; that is, two forward-slashes after the
|
|
"file:", a drive letter specification with a colon (not a pipe), and
|
|
forward-slashes in the path.
