Question

我搜索了我的概率并在网上找到了各种解决方案：

但是对我来说并不富有成效，因为在阅读xml后我将其保存在我的数据库中。

这是xml：

<root>
    −<Discounts>
        <DiscountID>1</DiscountID>
        <Title>WeekEnd Offers</Title>
        <Description>Offer upto 50%</Description>
        <SalePrice>50</SalePrice>
        <RegularPrice>100</RegularPrice>
        <CreatedDate>11/14/2011</CreatedDate>
        <LastModifiedDate>11/14/2011</LastModifiedDate>
        <Status>1</Status>
        <PhotoPath>/photos/documents/coupzila/hiteshi-logo.png</PhotoPath>
    </Discounts>
</root>

获取字符串中的描述：

  NSString * strDescription = [item.mdictXMLTagsData valueForKey:@"Description"];

    NSLog(@"String in description is : ",strDescription);

但是描述字段在控制台中变为空，我无法将其存储在我的数据库中。

请建议我如何阅读并将特殊字符存储到我的数据库中。

还有一件事让我知道＆amp;＃37是读取％符号的关键字，但我不知道n在哪里应用它。

请帮助!!!

编辑： - 希望你初始化currentParsedCharacter ......

这不是你的确切代码......但它应该是类似的......尝试一下，或者提供代码，我们可以帮助你做更好的事情。

-(id)init{
    if(self == [super init]){
        ObjectsMutableArray = [[NSMutableArray alloc] init];
        currentParsedCharacterData = [[NSMutableString alloc]init];
    }
    return self; 
}


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

}


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

    if([currentElement isEqualToString:@"Table"]) {
        obj = [[SomeClass alloc]init];
    }

    if ( [currentElement isEqualToString:@"Description"])
    {

        self.currentParsedCharacterData =(NSMutableString *) @"";
    }

}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
    if([currentElement isEqualToString:@"OtherThanDescription"]) {
        obj.CatName=[NSString stringWithFormat:@"%@",string];
        NSLog(@"CatName to be saved in Array :- %@",string);
    }

    else if([currentElement isEqualToString:@"Description"]) {

        NSMutableString *outputBuilder =  [[NSMutableString alloc]init] ;

        [outputBuilder appendString:[NSString stringWithFormat:@"%@", self.currentParsedCharacterData]];

        [outputBuilder appendString:[NSString stringWithFormat:@"%@", string]];

        self.currentParsedCharacterData = outputBuilder;

        [outputBuilder release];
    }

    else 
    {
        self.currentParsedCharacterData = (NSMutableString *)string;
    }
}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
    if([elementName isEqualToString:@"Table"]) {
        NSLog(@"Current element in End Element Category:- %@",currentElement);
        [ObjectsMutableArray addObject:obj];

    }
    if([elementName isEqualToString:@"Description"]) {
        obj.CatDesc = self.currentParsedCharacterData;
        NSLog(@"Current element in End Element Category:- %@",obj.CatDesc);

    }
    currentElement = @"";
}



- (void)parserDidEndDocument:(NSXMLParser *)parser
{
    appDelegate = (AppDelegate_iPhone *)[[UIApplication sharedApplication] delegate];
    appDelegate.ObjectsArray = [[NSMutableArray alloc]initWithArray:ObjectsMutableArray];

}

//然后将变量解除它......
