download and save an xml file

[JJSaccolo]

Hi everyone!

Like in the title: how can i download and save an xml file?
Because i know how to read, download and save the data in a "NSUserDefaults" file... but TBXML (the API that i'm using for parse the xml) need a real path, not a variable NSUserDefaults!

This is my code:

NSError *err = [[[NSError alloc] init] autorelease];
	NSString *url = [[NSString stringWithFormat:@"www.hello.com/hello.xml"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
	NSString *myTxtFile = [NSString stringWithContentsOfURL:[NSURL URLWithString:url] encoding:NSUTF8StringEncoding error:&err];
	if(err.code != 0) {
		//HANDLE ERROR HERE
	}
	//save
	[[NSUserDefaults standardUserDefaults] setObject:myTxtFile forKey:@"MyFile"];

now, TBXML need this code:

TBXML *tbxml = [[TBXML tbxmlWithXMLFile:@"hello.xml"] retain];

how can i save my online-xml in a offline-xml?

thanks

Files that your app saves are typically placed in the Documents subdirectory inside the directory where your application is installed. To get the path to this Documents folder, you can use these methods:

+ (NSString*)documentsDirectory
{
	NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
	return [[paths objectAtIndex:0] copy];
}

+ (NSString*)pathWithFilename:(NSString*)filename
{
	return [[self documentsDirectory] stringByAppendingPathComponent:filename];
}

Now you can call [self pathWithFilename:@"test.xml"] and this will return the full path to the file text.xml inside the Documents folder.
