Hi Jessie,
I was able to reproduce the problem you are seeing here (Intel
10.4.10/Xcode 2.4.1). NSXML bug?
Interestingly, if I edit your code to use the initWithData method, the
problem does not appear.
NSData *data = [NSData dataWithContentsOfURL:[NSURL
fileURLWithPath:pluginPath]];
NSXMLDocument *document = [[NSXMLDocument alloc] initWithData:data
options:0 error:&error];
Note: You'll probably want to set the URI if you use this workaround.
