leak at status parser method in libxml

I had a problem with the LibXMLParser when I开发者_JAVA技巧 ran it in the instruments. the following is my code that I used.

- (id)statusParser
{
    return [[[self class] alloc] init];
}

The memory is leaking at return method.

Did you try autorelease?

 - (id)statusParser
{
    return [[[[self class] alloc] init] autorelease];
}
