This article is about how IOS parses XML files. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

NSXMLParser is used to parse here, which is the xml parsing library that comes with apple.

Add a xml file to Xcode:

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

Read it first.

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]

Then parse:

# 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 (@" start parsing xml file ");}-(void) parserDidEndDocument: (NSXMLParser *) parser {[self.tableView reloadData] NSLog (@ "parsing xml file completed");}

The structure of Shopdata is:

@ 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; Thank you for reading!
