Having trouble with a leaky bit of code

Hey everyone,

I have a bit of code that is leaking and I can't seem to figure out why.

I have an XML Parser, and here's one of the snippets from its didEndElement method:

Code:

else if([elementName isEqualToString:@"link"])
	{
		NSString *link = [currentAttribute stringByReplacingOccurrencesOfString:@" " withString:@"%20"];
		[tempElement setLink:link];
	}

CurrentAttribute is an NSMutableString that I clear out every time I encounter a new object. tempElement is a custom object that I use to store parsed values.

I use the stringByReplacingOccurencesOfString method to remove spaces from links that I pull from an RSS feed.

Doing this should return an autoreleased object, right?

It seems this bit of code leaks though. Any thoughts?
