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
