Question

I have this xml file:

<?xml version="1.0" encoding="UTF-8"?>
<Favorites>
    <favorite id="1">
        <title>My first favorite</title>
        <latitude>31.369834</latitude>
        <longitude>34.798207</longitude>
    </favorite>
</Favorites>

and I want to write more “favorite”s into it.
I have all the data I need as strings in my project.
But I can’t figure out how to really do it – although I have tried a lot.

can you please help me do it ?
thanks.

I agree with the responders that you should consider using a .plist file. Creating NSDictionary objects of your “Favorite” objects, and saving the array of them.

But, to your immediate question, you could save a NSString representing your XML like this (but again, saving a string based XML means a lot of parsing and interaction methods created by you):

// Build The Path
//
NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, 
                                                      NSUserDomainMask, 
                                                      YES);

NSString * filePath = [paths objectAtIndex:0];

filePath = [filePath stringByAppendingPathComponent:@"favorites"];
filePath = [filePath stringByAppendingPathExtension:@"xml"];


// You Should Have A "Favorite" Objects That Know How To Desribe Themselves...
//
NSString * badWayToDoThis = @"<ThinkAboutUsingDictionaries>Saving The Data to a plist</seriously>";

[badWayToDoThis writeToFile:filePath 
                 atomically:YES 
                   encoding:NSUTF8StringEncoding 
                      error:NULL];

Hope that at the very least gets you towards where you’re headed.
