如何在 iphone sdk 中解析嵌套的 XML

Question

我想解析以下 XML，但我很困惑如何解析它，因为我在一条记录中有多个嵌套。谁能给我一个建议吗？

Answer 1

NSData *data=[NSData dataWithContentsOfURL:myUrl.mURL];
NSString *string=[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
DDXMLDocument *doc=[[[DDXMLDocument alloc] initWithXMLString:string options:0 error:nil] autorelease];
NSArray *docs=[doc nodesForXPath:@"//item" error:nil];
NSLog(@"Doc Count%i",[docs count]);

for (DDXMLElement *documents in docs)
{}

然后在这个for循环中你可以做这样的事情：

DDXMLNode *childNode=[documents childAtIndex:k];
DDXMLElement *childElement=(DDXMLElement *)childNode;
book.title=[childElement stringValue] ;
book.podLink=[[childElement attributeForName:@"url"] stringValue];//For Attributes
