如果字符串包含 – 则解析器换行

我的 NSXMLParser 在这个字符串上中断：

<title>AAA &#8211; BCDEFGQWERTYUIO</title>

我以这种方式解析它，希望是正确的方式：

- (void) parser: (NSXMLParser *) parser foundCharacters: (NSString *) string{
[...]
if ([currentElement isEqualToString:@"title"]) {
    if (![string isEqualToString:@""]) {
            [title addObject:string];
            NSLog(@"str: %@", string);
    }
}

它返回我：

str：AAA
str：-
str：BCDEFGQWERTYUIO

但我想返回单个字符串：

str：AAA - BCDEFGQWERTYUIO

因为它是正确的标题。

有什么想法吗？

谢谢。

My NSXMLParser breaks on this string:

<title>AAA – BCDEFGQWERTYUIO</title>

I parsed it in this way, hope is the right way:

- (void) parser: (NSXMLParser *) parser foundCharacters: (NSString *) string{
[...]
if ([currentElement isEqualToString:@"title"]) {
    if (![string isEqualToString:@""]) {
            [title addObject:string];
            NSLog(@"str: %@", string);
    }
}

it returns me:

str: AAA
str: -
str: BCDEFGQWERTYUIO

But i want to return a single string:

str: AAA - BCDEFGQWERTYUIO

because it's the correct title.

Any idea?

Thanks.

我发现最好在 didEndElement 方法中创建对象。这样您就可以继续将字符串数据附加到某个临时字符串中。所以你可能会做类似下面的事情（注意：代码未测试）

在你的对象头中：

NSMutableString *currentElementData;

...

@property (nonatomic, retain) NSMutableString *currentElementData;

在你的解析代码中你会

- (void) parser: (NSXMLParser *) parser foundCharacters: (NSString *) string{
[...]
if ([currentElement isEqualToString:@"title"]) {
    [currentElementData appendString:string];
    }
}

然后在你的元素中结束

   - (void) parser: (NSXMLParser *) parser didEndElement: (NSString *) elementName...{
    [...]
    if ([elementName isEqualToString:@"title"]) {
        [title addObject:currentElementData];
         [currentElementData setString:@""];
        }
    }

I find that it is better to create your object in the didEndElement method. That way you can just keep appending the string data to some temporary string. So you might do something like below (NOTE: code not tested)

In your object header:

NSMutableString *currentElementData;

...

@property (nonatomic, retain) NSMutableString *currentElementData;

And in your parsing code you would have

- (void) parser: (NSXMLParser *) parser foundCharacters: (NSString *) string{
[...]
if ([currentElement isEqualToString:@"title"]) {
    [currentElementData appendString:string];
    }
}

Then later in your element did end

   - (void) parser: (NSXMLParser *) parser didEndElement: (NSString *) elementName...{
    [...]
    if ([elementName isEqualToString:@"title"]) {
        [title addObject:currentElementData];
         [currentElementData setString:@""];
        }
    }
