问题描述

我有一个Web服务,对DataBase进行了不同的更改。当我使用带有sql标签的webservice返回行时,如下所示:

I have a webservice with diferent changes for the DataBase. When I consume the webservice return lines with sql tags, like this:

<sql>
   DELETE FROM TABLE WHERE ...
</sql>
<sql>
   INSERT INTO TABLE WHERE ...
</sql>
<sql>
   UPDATE TABLE SET ... WHERE ...
</sql>

我将此代码保存在NSMutableArray中,如下所示:

I save this codes in the NSMutableArray like this:

-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName  namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName  {
    if ([elementName isEqualToString:@"sql"]){
        [maResultado addObject:[NSMutableString stringWithFormat:@"%@", ResultadoSoap]];
        [ResultadoSoap setString:@""];
    }
}

这很好,但是如果webservice返回一个字带有重音(重音因为是西班牙语),应用程序只在重音后获得短语。
示例:
网络服务返回此信息:

This is good, but if the webservice returns a word with an accent (accent because is in spanish), the app only get the phrase after the accent. Example: the web service return this:

<sql>
   INSERT INTO DATOS(datos, fecha) VALUES('Indagar si el médico a tenido oportunidad de ...', '20/02/2013')
</sql>

我这样做:

if ([elementName isEqualToString:@"sql"]){
    [maResultado addObject:[NSMutableString stringWithFormat:@"%@", ResultadoSoap]];
    [ResultadoSoap setString:@""];
}

并且在objectatindex的maResultado中只有这个:

and in the maResultado in the objectatindex only have this:

édico a tenido oportunidad de ...', '20/02/2013')


推荐答案

解析器:foundCharacters:委托函数可以调用更多而不是一次XML元素。如果字符内容包含特殊字符,则会发生这种情况。在您的情况下,对于数据

The parser:foundCharacters: delegate function can be called more than once for an XML element. This happens in particular if the character content contains special characters. In your case, for the data

<sql>
   INSERT INTO DATOS(datos, fecha) VALUES('Indagar si el médico a tenido oportunidad de ...', '20/02/2013')
</sql>

委托函数被调用两次,首先是字符串

the delegate function is called twice, first with the string

INSERT INTO DATOS(datos, fecha) VALUES('Indagar si el m

然后再用字符串

édico a tenido oportunidad de ...', '20/02/2013')

因此,您必须追加字符串在解析器:foundCharacters:到当前字符串,例如

Therefore, you have to append the string in parser:foundCharacters: to the current string, e.g.

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
    [currentElementValue appendString:string];
}
