我有一个问题是获得A-> 1,2,3,4＆amp;的价值b-> 1,2,3,4
我必须在3张桌子上显示这些数据
表1）A，B 表2）当用户点击A - ＆gt;他可以看到1,2,3,4的桌面形式 但我的情况我只能显示A的最后一个值，即4（不是1,2,3）
如何解析所有1,2,3,4
<?xml version="1.0" encoding="UTF-8"?>
<hall>
<movie Name="A">
<stall Name="1">
<description>qwe.</description>
<rating>5</rating>
</stall>
<stall Name="2">
<description>wer.</description>
<rating>5</rating>
</stall>
<stall Name="3">
<description>wer.</description>
<rating>5</rating>
</stall>
<stall Name="4i">
<description>wer.</description>
<rating>5</rating>
</stall>
</movie >
<movie Name="B">
<stall Name="t1">
<description>wer.</description>
<rating>5</rating>
</stall>
<stall Name="2">
<description>wer.</description>
<rating>5</rating>
</stall>
<stall Name="3">

<rating>5</rating>
</stall>
<stall Name="4">

<rating>5</rating>
</stall>
</movie>
</hall>

我的数组我的appDelegate.HospN：值是（ 1， 2， 3， 4I， T1， 2， 3， 4 ） **但我想在A = 1,2,3,4i
处砍掉数据和B = t1,2,3,4 **
如何获取描述和评级的值？
else if([elementName isEqualToString:@"description"])
{
NSLog(@"desp List : \n%@\n",currentElementValue);// i can see all value but how to chop data based on A and B
[movieList setObject:currentLink forKey:@"description"];
[appDelegate.despArray addObject:[movieList copy]];
NSLog(@"adding story: %@",currentLink);
}
else if([elementName isEqualToString:@"rating"])
{
}
答案 0 :(得分：0)
通过观察xml，你会发现这样的关系......
一个大厅可以有一部或多部电影，每部电影都可以有一个或多个电影。
所以你能做的就是。
在xml解析类中有一个实例字典，比如movieList，一个实例数组，例如stallNames和一个movieName，NSString。
movieList：将电影名称与各自的档位映射。（NSMutableDictionary） stallNames：将包含与特定电影相关的档位。（NSMutablArray） currentMovie：将具有当前电影名称，因为它将用作movieList字典中的键。（NSString）
现在在startElement方法......
if([elementName isEqualToString:@"hall"])
{
movieList = [[NSMutableDictionary alloc]init];
}
else if([elementName isEqualToString:@"movie"])
{
currentMovie = [[NSString alloc] initWithString:[attributeDict objectForKey:@"Name"]] ;
stallNames = [[NSMutableArray alloc]init];
}
else if([elementName isEqualToString:@"stall"])
{
[stallNames addObject:[attributeDict objectForKey:@"Name"]];
}
didEndElement方法中的
if([elementName isEqualToString:@"hall"])
{
NSLog(@"Movie List : %@",movieList);
}
else if([elementName isEqualToString:@"movie"])
{
[movieList setObject:stallNames forKey:currentMovie];
[currentMovie release];
[stallNames release];
currentMovie = nil;
stallNames = nil;
}
else if([elementName isEqualToString:@"stall"])
{
//you can populate other attributes here if stall is not just string but a modal class.
}
注意：就像上面发布的代码一样，你有一个Book类，它似乎代表了Movie，所以你可以做的是，有另一个属性，它将是数组类型摊位名称。这个Book对象将在稍后的数组中添加（当你遇到elementName“movie”时，在didEndElement中）。将此数组作为实例变量，并在startElement中遇到“hall”标记时对其进行初始化。
更新ANS （根据新规范）
//declare following instance variables. I am leaving aBook variable because I am not sure of its use.
NSMutableDictionary *movieList;
NSMutableArray *stallArray;
NSMutableString *currentMovieKey;
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
attributes:(NSDictionary *)attributeDict {
if([elementName isEqualToString:@"hall"])
{
movieList = [[NSMutableDictionary alloc]init]; // it will contain list of all the movies in the xml.
}
else if([elementName isEqualToString:@"movie"])
{
currentMovieKey = [[NSMutableString alloc] initWithString:[attributeDict objectForKey:@"Name"]] ; // will be used for setting key for stallArray.
stallArray= [[NSMutableArray alloc] init]; // it will contain stall names.
}
else if([elementName isEqualToString:@"stall"])
{
[stallArray addObject:[attributeDict objectForKey:@"Name"]];
}
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
if(!currentElementValue)
currentElementValue = [[NSMutableString alloc] initWithString:string];
else
[currentElementValue appendString:string];
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
if([elementName isEqualToString:@"hall"])
{
//parsing finished...end of root tag. movieList will be the final dictionary that will have your data
NSLog(@"Movie List : \n%@\n",movieList);
}
else if([elementName isEqualToString:@"movie"])
{
[movieList setObject:stallArray forKey:currentMovieKey];
[currentMovieKey release];
currentMovie = nil;
[stallArray release];
stallArray = nil;
}
else if([elementName isEqualToString:@"stall"])
{
//you can populate other attributes here if stall is not just string but a modal class.
}
//I was not sure about your else part...
[currentElementValue release];
currentElementValue = nil;
}
谢谢，
