我想解析XML文件中的可可Application.but沒有解析器XML工作well.Please幫助解析該文件或其他XML像這樣的文件。謝謝...我的XML文件是在：

<book name="Genesis"> 
    <chapter number="1"> 
     <verse number="1">At the first God made the heaven and the earth.</verse> 
     <verse number="2">And the earth was waste and without form; and it was dark on the face of the deep: and the Spirit of God was moving on the face of the waters.</verse> 
     <verse number="3">And God said, Let there be light: and there was light.</verse>

Answer 1

有有效的兩種方法來解析XML - 事件驅動的一個（如由使用的NSXMLParser）和樹的方法（如通過使用NSXML ）。

如果您只是在特定元素之後，那麼使用NSXML使用的樹方法可能會容易得多，因爲它可以使您使用XPath（實際上是XQuery）查詢XML文檔以返回特定節點等你感興趣。

如果這聽起來像是使用NSXMLParser遍歷整個結構可能是更有成效的方法，那麼我建議讀the Introduction to Tree-Based XML Programming Guide for Cocoa。 （在「查詢XML文檔」部分應該是特別感興趣的。）

Answer 2

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{  
    if ([elementName isEqualToString:@"book"]) 
    { 
    item = [[NSMutableDictionary alloc] init]; 

     item_name = [[NSMutableString alloc] initWithString:[attributeDict valueForKey:@"name"]]; 
} 

//然後在ITEM_NAME你有值創
//嘗試解析這樣
編輯：看了之後註釋

if ([elementName isEqualToString:@"verse"]) 
     { 

      item_name1 = [[NSMutableString alloc] initWithString:[attributeDict valueForKey:@"number"]]; 
    } 

//在item_name1你將得到的值作爲1次
