Dear Tito, Scott and all,

Thanks so much for your replies!

I think the memory management in my system is much better. I just used
Instruments to check potential leaks. To my surprise, I was still notified
that the following method got memory-leaking although the amount was small.
Could you please tell me how to fix this problem? Maybe I just ignore it?

+ (NSString *)read:(NSString *)xml Path:(NSString *)xPath
{
        // The Instruments indicated the following line got memory leaks.
The amount of leaked memory was not large (about 400KB)
        NSXMLDocument *xmlDoc = [[NSXMLDocument alloc] initWithXMLString:xml
options:NSXMLDocumentTidyXML error:NULL];

        NSArray *nodes = [xmlDoc nodesForXPath:xPath error:NULL];
        [xmlDoc release];
        if ([nodes count] > 0)
        {
                return [[nodes objectAtIndex:0] stringValue];
        }
        else
        {
                return @"";
        }
}


Best regards,
Bing Li
