IOS如何解析XML文件

这篇文章给大家分享的是有关IOS如何解析XML文件 的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

这里使用NSXMLParser来解析，这个是apple自带的xml解析库

在Xcode中加入一个xml文件:

    001    John    Reminder    Don't forget the meeting!    002    Jack    cc    how are you!    003    Tom    bb    I am fine!

先读出来

   NSString* path =  [[NSBundle mainBundle] pathForResource:@"shop" ofType:@"xml"];    NSData *data = [[NSData alloc] initWithContentsOfFile:path options:(NSDataReadingMappedIfSafe) error:nil];    NSXMLParser *parser=[[NSXMLParser alloc] initWithData:tmpdata];     [parser setDelegate:self];        [parser parse];        [parser release];    [self parseShopListFromResponse:data];

然后进行解析:

#pragma mark NSXMLParser delegate methods- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName  namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qName        attributes: (NSDictionary *)attributeDict {    self.currentTag = elementName;        if ([elementName isEqualToString:@"root"]) {                self.tmpList = [[NSMutableArray alloc] init];        }else if ([elementName isEqualToString:@"Shop"]) {                self.tmpShop = [[ShopData alloc] init];        NSArray* array = [attributeDict allKeys];        NSString* key = [array lastObject];        NSString*s  = [attributeDict objectForKey:key];        self.tmpShop.info = s;        }}-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {    if (self.currentString == nil) {        self.currentString = [[NSMutableString alloc] initWithString:@""];    }        if ([self.currentTag isEqualToString:@"name"] ||        [self.currentTag isEqualToString:@"id"] ||        [self.currentTag isEqualToString:@"url"] ||        [self.currentTag isEqualToString:@"info"]) {        [self.currentString appendString:string];        }}-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {         if ([elementName isEqualToString:@"Shop"]) {                [self.tmpList addObject:self.tmpShop];        [self.tmpShop release];        } if ([elementName isEqualToString:@"name"]) {        self.tmpShop.name = [self.currentString copy];        [self.currentString setString:@""];        }else if ([elementName isEqualToString:@"id"]) {                self.tmpShop._id = [self.currentString copy];        [self.currentString setString:@""];        }else if ([elementName isEqualToString:@"url"]) {                self.tmpShop.url = [self.currentString copy];        [self.currentString setString:@""];        }else if ([elementName isEqualToString:@"info"]) {//              self.tmpShop.info = [self.currentString copy];//        [self.currentString setString:@""];        }}- (void)parserDidStartDocument:(NSXMLParser *)parser {        NSLog(@"开始解析xml文件");}- (void)parserDidEndDocument:(NSXMLParser *)parser {                [self.tableView reloadData];        NSLog(@"解析xml文件完成");}

Shopdata的结构是:

@property (nonatomic,retain) NSString *name;@property (nonatomic,retain) NSString *url;@property (nonatomic,retain) NSString *_id;@property (nonatomic,retain) NSString *info;@property (nonatomic, retain) UIImage *appIcon;
