適用於iPhone的SAX XML解析器示例在iOS中

Question

有人可以在XCode中發佈SAX XML解析器示例鏈接，而不是來自developer.apple.com。 我需要解析這個XML文件：

<?xml version="1.0" encoding="UTF-8"?>

，但是從文檔上http://developer.apple.com/library/ios/#documentation/Cocoa/Conceptual/XMLParsing/Articles/UsingParser.html#//apple_ref/doc/uid/20002264-BCIIJEEH也不清楚我。 這是我有：

#pragma mark *** NSXMLParserDelegate *** 

- (void)parserDidStartDocument:(NSXMLParser *)parser 
{ 
    // do preparation for loading data from XML 
} 

- (void)parserDidEndDocument:(NSXMLParser *)parser 
{ 
    [parser release]; 
} 

- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError 
{ 
    //analyze parseError 
    [parser release]; 
} 

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict 
{ 
    NSLog(@"elementName %@", elementName); // current parsing element 
    // specify type of data to be saved in method below 
} 

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string 
{ 
    NSLog(@"value of element %@", string); // value for current parsing element 
    // save data to some ivar for future use (displaying) 
} 

謝謝。

您可能想參加以下鏈接。 http://homepages.ius.edu/RWISMAN/C490/html/nsxmlparser.htm 它甚至在頁面上有一個例子。上面的解析應該足夠簡單。提供更多的洞察力，確切地說是你的問題將有所幫助。
