Question

嗨我有一个非常奇怪的问题我有xml文件whit 21个元素，我想将它们添加到可变数组。解析器11次启动元素，11次foundCharacters但只有10次结束元素，它表现得像它结束xml文件。我的程序不会像它应该运行一样下降和运行。但有时它会使它应该如此，所以它读取所有21个元素。为什么呢？

我的代码的一部分：

 /*this function start work whith xml file*/

- (void)parseXMLFile:(NSData *)adatok {
    if (adatok != nil) {
        BOOL success;
        if (addressParser) 
            [addressParser release];
        addressParser = [[NSXMLParser alloc] initWithData:adatok];
        [addressParser setDelegate:self];
        [addressParser setShouldResolveExternalEntities:YES];
        success = [addressParser parse]; 

    }
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {
    NSLog(elementName);
    if ([elementName isEqualToString:@"turnover"]) {
        objektObrat =[[Obrat1 alloc] init]; 
        NSString *sth = [attributeDict objectForKey:@"transid"];
        objektObrat.uID = sth;
    }
    if ([elementName isEqualToString:@"amount"]) {
        osuma=YES;
    }
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
//filling the object which will be saved in database    
    NSLog(string);
    if (osuma) {
        osuma=NO;
        objektObrat.suma = [[NSString alloc] initWithString:string];
    }
}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
    NSLog(elementName);
    if ([elementName isEqualToString:@"turnover"]) {
        turnOver = NO;
        oid = NO;

        if (objektObrat != Nil){
            [obratDatabaseArray addObject:objektObrat];
            [objektObrat release];
        }
        //add to array
        [array addObject:vypisObratString];
    }

    if ([elementName isEqualToString:@"amount"]) {
        osuma=NO;
    }
}

我希望它有所帮助，至少有一个关键，我应该寻找问题感谢

好吧，它可能是CDATA。如果你有一个有CDATA的标签，那么CData将通过函数

进行解析

- (void)parser:(NSXMLParser *)parser foundCDATA:(NSData *)CDATABlock

检查一下。

NsXmlParser无法正常工作
