IOS解析XML文件

这里使用NSXMLParser来解析，这个是apple自带的xml解析库，有个参考文章：http://www.php.cn/

在Xcode中加入一个xml文件:

<?xml version="1.0" encoding="ISO-8859-1"?><root><Shop shoplocation="beijing">    <id>001</id>    <name>John</name>    <url>Reminder</url>    <info>Don't forget the meeting!</info></Shop><Shop shoplocation="dongcheng">    <id>002</id>    <name>Jack</name>    <url>cc</url>    <info>how are you!</info></Shop><Shop shoplocation="haidian">    <id>003</id>    <name>Tom</name>    <url>bb</url>    <info>I am fine!</info></Shop></root>

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];<span style="white-space:pre"></span>[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 *)qNameattributes: (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;
