NSXMLParser无法解析特殊字符(重音符号)

Question

我正在使用NSXMLParser从url解析xml(我的代码与此处的代码几乎完全相同)

一些元素包含特殊字符,如"á",这使得一个单词很可能被分成两个(á和ndre).

这是我的loadXMLByURL

-(id) loadXMLByURL:(NSString *)urlString{
tickets     = [[NSMutableArray alloc] init];
NSURL *url      = [NSURL URLWithString:urlString];
NSData  *data   = [[NSData alloc] initWithContentsOfURL:url];
parser          = [[NSXMLParser alloc] initWithData:data];
parser.delegate = self;
[parser parse];
return self;}

我很确定这是因为没有设置编码(我认为它需要是NSUTF8StringEncoding)但我不知道在哪里/如何应用它.

[更新]我的其余代码......

- (void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{    
    if ([elementname isEqualToString:@"ticket"]) 
    {
        currentTicket = [Ticket alloc];
    }

}

- (void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
    if ([elementname isEqualToString:@"name"]) 
    {
        currentTicket.name = currentNodeContent;
    }
    else if ([elementname isEqualToString:@"title"]) 
    {
        currentTicket.title = currentNodeContent;
    }
    else if ([elementname isEqualToString:@"status"]) 
    {
        currentTicket.status = currentNodeContent;
    }
    else if ([elementname isEqualToString:@"ticket"])
    {
        [tickets addObject:currentTicket];
        [currentTicket release];
        currentTicket = nil;
        [currentNodeContent release];
        currentNodeContent = nil;
    }

}

- (void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
    currentNodeContent = (NSMutableString *) [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
}

[更新2]示例xml ...

<RB>
    <list>
        <ticket>
            <name>Andrew Ford</name>
            <title>3rd release</title>
            <status>1</status>
        </ticket>

        <ticket>
            <name>David Jenkins</name>
            <title>3rd release</title>
            <status>0</status>
        </ticket>

        <ticket>
            <name>Luis gomez ándre</name>
            <title>3rd release</title>
            <status>1</status>
        </ticket>
    </list>
</RB>

我会将网址加载到一个NSString 然后转换为这样.

-(id) loadXMLByURL:(NSString *)urlString{

    tickets     = [[NSMutableArray alloc] init];
    NSURL *url      = [NSURL URLWithString:urlString];
    NSError *error;
    NSString * dataString = [[NSString alloc] initWithContentsOfURL:url encoding:NSUTF8StringEncoding error:&error];
    NSData *data = [dataString dataUsingEncoding:NSUTF8StringEncoding];
    parser          = [[NSXMLParser alloc] initWithData:data];
    parser.delegate = self;
    [parser parse];
    return self;

}

编辑:部分问题可能是您的parser:foundCharacters:方法分配给您currentNodeContent而不是追加.请通过以下链接查看Apple Doc.

来自doc:

因为字符串可能只是当前元素的总字符内容的一部分,所以应该将其附加到当前字符的累积,直到元素更改为止.
