Question

I want to create a game, that will use a level system. So i want to store my levels and to be able to change them during the game (to save the state). So i decided to use XM

Answer 1

If you throw the data in an NSDictionary, you could do (with caveats):

[myDictionary writeToFile:pathToPlist atomically:YES];

Answer 2

I would recommend using KissXML. The author started in a similar situation as you and created an NSXML compatible API wrapper around libxml. He discusses the options and decisions here on his blog.

Answer 3

You can use the C libary libxml2 to read and write XML. Here's a quick intro: Cocoa Samurai: Getting Some XML Love with libXML2.

However, have you considered using CoreData or implementing the NSCoding protocol? NSCoding would be easier to add to existing classes.

Answer 4

Try the open source XML stream writer for iOS:

• Written in Objective-C, a single .h. and .m file
• One @protocol for namespace support and one for without

Example:

// 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];

This produces the following XML string:

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