iphone利用xml传递数据，展示载Table界面中
下面主要说一下xml的读取，iphone sdk已经给我们实现好了NSXMLParser，我们只需继承重写一些方法既可。
代码声明：
#import <Foundation/Foundation.h>
@interface XmlWelcome : NSXMLParser {
NSMutableArray * ones ;
NSMutableDictionary * one ;
int inOne;
int inTwo;
int Tag ;
}
@property (nonatomic ,retain ) NSMutableArray *ones;
@end
声明实现：
#import “XmlWelcome.h”
@implementation XmlWelcome
@synthesize ones;
// 开始一个dom 树分析
- (void )parserDidStartDocument:(NSXMLParser *)parser {
NSLog ( @”开始分析树结构 “);
ones = [ NSMutableArray arrayWithCapacity: 100 ];
}
// 开始节点 内的信息
- (void )parser:(NSXMLParser *)parser
didStartElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qualifiedName
attributes:(NSDictionary *)attributeDict
{
NSLog (@” 开始的节点是 :%@” ,elementName);
if ([elementName isEqual :@"title" ]) {
Tag =1 ;
}else if ([elementName isEqual :@"content" ]) {
Tag =2 ;
}
if ([elementName isEqual :@"item" ]) {
NSString *lang=[attributeDict objectForKey :@"lang" ];
if ([lang isEqual :@"zh" ]) {
inOne =1 ;
}
}
if (inOne ==1 &&[elementName isEqual :@"value" ]) {
inOne= 0 ;
inTwo= 1 ;
}
if ([elementName isEqual :@"image" ]) {
NSString *message=[attributeDict objectForKey :@"src" ];
[one setObject :message forKey :@"image" ];
}
}
// 结束节点
- (void )parser:(NSXMLParser *)parser
didEndElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName
{
NSLog (@” 结束节点 :%@” ,elementName);
if ([elementName isEqual :@"pavilion" ]) {
Tag =0 ;
[ ones addObject: one ];
[ one release];
}
}
// 结束 dom
- (void )parserDidEndDocument:(NSXMLParser *)parser
{
NSLog ( @”结束 dom树分析 “);
}
- (void )parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
NSLog ( @”节点的实际值： %@”,string);
if (inTwo ==1 ) {
inTwo= 0 ;
if (Tag ==1 ) {
one =[[ NSMutableDictionary alloc] initWithCapacity: 10 ];
[one setObject :string forKey :@"title" ];
}else if (Tag ==2 ) {
[one setObject :string
forKey : @"content"];
}
}
}
@end
里面有些算法比较烂，我也是初学着，大家共同讨论。
