Memory leak when parsing xml

I'm trying to parse an xmlfile almost like the seismicXML sample. What I do is the following:

I have created a object called XMLReader exactly like in the sample from apple. And then to init the object and start parsing:

NSURL *myUrl = [NSURL URLWithString:sendUrl];
XMLReader *streamingParser = [[XMLReader alloc] init];
[streamingParser parseXMLFileAtURL:myUrl parseError:&parseError];
[streamingParser release];
NSLog([NSString stringWithFormat:@"retainCount of myUrl: %i",[myUrl retainCount]]);

In the parseXMLFileAtURL:

NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL:URL];
[parser setDelegate:self];
[parser parse];
[parser release];

In instruments I can see I have a memory leak with NSMachPort and CFRunLoopSource (whats this?) both seem to come from the parseXMLFileAtURL. What I can see is also that myUrl have a retainCount of how the same size as how many rows I have parsed from the xml when writing it to the log. 7 in my case, so I think this is maybe what's wrong but I'm not sure how to do this, I can't release myUrl as I'm not init it? And in the parseXMLFileAtURL all I do is passing it onto the initWithContentsOfURL-method, can't see whats wrong here, anyone?

Thanks really much for your help!
