I'm using NSXMLDocument's initWithContentsOfURL: method, and I think
I'm running into some issues with NSURL caching the data at times. I
see that there are lots of options with NSURLRequest and it's
brethren, but it's not clear to me how to merge this with the NSURL
required by NSXMLDocument's initWithContentsOfURL:
Any pointers on this would be great.
The NSURL instance that NSXMLDocument's
initWithContentsOfURL:options:error: wants is simply just an URL, like
http://foo.com/xml.php or file://Users/peylow/test.xml.
The NSURLRequest is a bit more complex, it can also post form data and
such. I can not see any way to swap the two unless you also use the
NSURLRequest object with a NSURLConnection's
sendSynchronousRequest:returningResponse:error: method to get a NSData
object. And then use that to init the NSXMLDocument using the
initWithData:options:error: method instead.
Something like:
NSURL *url = [NSURL URLWithString:someURLString];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSURLResponse *response;
NSData *data = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response error:nil];
NSXMLDocument *document = [[NSXMLDocument alloc] initWithData:data
options:NSXMLNodeOptionsNone error:nil];
But my guess is that this is pretty much what
initWithContentsOfURL:options:error: does internally anyway.
