iPhone开发 - 生成XML文件

Question

这里有人知道如何在iPhone中生成XML文件或字符串吗？

Answer 1

<?xml version="1.0" encoding="UTF-8"?> <parent> 
<child name="James"> <age>10</age> <sex>male</sex> 
</child> </parent> 
</xml> 

像我用这个XML 写在.h文件中........

#import <UIKit/UIKit.h> 
@interface RootViewController : UIViewController <NSXMLParserDelegate> { 
@public 
} 
NSXMLParser *myXMLParser; 
@property (nonatomic, retain) NSXMLParser *myXMLParser; 
@end 
write in .m file 
- (void)viewDidLoad { [super viewDidLoad]; 
NSBundle *mainBundle = [NSBundle mainBundle]; 
NSString *xmlFilePath = [mainBundle pathForResource:@"MyXML" ofType:@"xml"]; 
if ([xmlFilePath length] == 0){ /* The file could not be found in the resources folder. 
} 
return; 
/* Let's see if the XML file exists... */ 
NSFileManager *fileManager = [[NSFileManager alloc] init]; 
if ([fileManager fileExistsAtPath:xmlFilePath] == NO){ 
/* The XML file doesn't exist, we double checked this just to make sure we don't leave any stones unturned. You can now throw an error/exception here or do other appropriate processing */ 
NSLog(@"The file doesn't exist."); 
[fileManager release]; 
return; 
[fileManager release]; 
/* Load the contents of the XML file into an NSData */ NSData *xmlData = [NSData dataWithContentsOfFile:xmlFilePath]; 
NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:xmlData]; 
self.myXMLParser = xmlParser; [xmlParser release]; 
[self.myXMLParser setDelegate:self]; 
if ([self.myXMLParser parse] == YES){ 
/* Successfully started to parse */ } else { 
} 
/* Failed to parse. Do something with this error */ 
NSError *parsingError = [self.myXMLParser parserError]; 
NSLog(@"%@", parsingError); 

- (void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName 

namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName 
attributes:(NSDictionary *)attributeDict 
{ 
NSLog(@"Element Name = %@", elementName); 
NSLog(@"Number of attributes = %lu",(unsigned long)[attributeDict count]); 
if ([attributeDict count] > 0) 
{ 
NSLog(@"Attributes dictionary = %@", attributeDict); 
NSLog(@"========================"); 
} 
} 

Answer 2

尝试开源XML stream writer for iOS：

• 用Objective-C ，单一的.h。和.m文件命名空间支持
• 一个@protocol，一个用于无

例子：

// allocate serializer 
XMLWriter* xmlWriter = [[XMLWriter alloc]init]; 

// start writing XML elements 
[xmlWriter writeStartElement:@"Root"]; 
[xmlWriter writeCharacters:@"Text content for root element"]; 
[xmlWriter writeEndElement]; 

// get the resulting XML string 
NSString* xml = [xmlWriter toString]; 

这将产生以下XML字符串：

<Root>Text content for root element</Root>
