看看下面的代码，它可能对你有帮助:)

-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
       attributes:(NSDictionary *)attributeDict {

        if([elementName isEqualToString:@"string"])
            urlStr = [[NSString alloc] init];

    }

    - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
        if(!currentElementValue)
            currentElementValue = [[NSString alloc] init];

        currentElementValue = [NSString stringWithFormat:@"%@",string];
    }

    - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
    {
        if([elementName isEqualToString:@"string"])
           urlStr = [NSString stringWithString:currentElementValue];

    }

    - (void)parserDidEndDocument:(NSXMLParser *)parser {

    }
