Question

我有这样的xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <background>assets/_image.png</background>
    <items>
        <item type='test1' position='6' x='123' y='456'>
            my_way
        </item>
        <item type='test2' position='8' x='456' y='123'>
            another_way
        </item>

.........................

我使用NSXMLParser读取了它：

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
    if ([self.currentTag isEqualToString:@"item"]) {
        [self addItemForAttributes:self.currentAttributes withValue:string];

        NSLog(@"%@", self.items.lastObject.type);
        NSLog(@"%@", self.items.lastObject.position);
        NSLog(@"%@", NSStringFromCGPoint(self.items.lastObject.coordinate));
        NSLog(@"%@", self.items.lastObject.value);
    }
}

我将项目写入项目数组。但是当我在控制台中阅读它时，有些项目看起来像是重复的。

如何解决？

Answer 1

多次调用委托方法（找到字符），我为此做条件（过滤空字符串），所以解决了我的问题。
