iphone - NSXMLParser 委托(delegate)处理属性

Question

我目前正在尝试让我的解析器委托(delegate)使用自定义 NSObject我已经为我收到的 xml 的属性创建了..

这是正在读入我的解析器委托(delegate)的 XML

<Rows>
<Row SKATERID="706" MANUFACTURER="GAZ" ISFACT="F" ISSKATE="F"/>
<Row SKATERID="318" MANUFACTURER="MAN" ISFACT="F" ISSKATE="T"/>
//...
</Rows>

这就是我的 -parser:didStartElement:namespaceURI:qualifiedName:attributes:方法:

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
    if ( [elementName isEqualToString:@"Row"]) {

        manufactureNSObject = [[ManufactureNSObject alloc] init];

        manufactureNSObject.ISFACT = [attributeDict objectForKey:@"ISFACT"];
         manufactureNSObject.ISSKATE = [attributeDict objectForKey:@"ISSKATE"];
         manufactureNSObject.MANUFACTURER = [attributeDict objectForKey:@"MANUFACTURER"];
         manufactureNSObject.SKATERID = [attributeDict objectForKey:@"SKATERID"];

        NSLog(@"%@ %@ %@ %@", manufactureNSObject.ISFACT, manufactureNSObject.ISSKATE, manufactureNSObject.MANUFACTURER, manufactureNSObject.SKATERID);
    }    
} 

我的 NSLog打印出所有正确的值，我坚持的下一部分是 - parser:didEndElement:namespaceURI:qualifiedName:方法，除了 didEndElement正确地通过了......这就是我所拥有的那种方法。

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
    NSLog(@"%@", elementName);
    NSLog(@"%@", namespaceURI);
    NSLog(@"%@", qName);
}

这是 NSLog 中我的输出的样子s。

我特别想帮助我尝试完成第二种方法并让这一切正常工作。

到目前为止，所有的帮助都非常感谢。

对于您正在解析的 xml 文件的类型，

parser:foundCharacters:

永远不会被调用。在这种情况下会调用此委托(delegate)方法:

<mytag>this is the tag content</mytag>

while in your case only attributes are present and no tag content, that is:

<mytag attr1="value1" attr2="value2"></mytag>

As far as the other method:

parser:didEndElement:

它的实现取决于你。例如。如果将元素存储在临时变量中，则此方法可用于将此变量复制到另一个数据结构中。
