Ok, I need to rephrase the question to use the proper terms.
How can I save a string in a plist inside <string></string> tags so
that the string is saved with character escaping for the '\r' (and
probably '\n') characters?
This is done automatically for the & character.
Have you given this a test as is? For example, in F-Script (a sort of
Objective-C scripting language) I tried this:
dict1 := NSDictionary dictionaryWithObjects:{'this is\r a test\r',
'\r\rthis is another test\r\r'} forKeys:{'a', 'b'}
dict1 writeToFile:'/Users/foo/test.plist' atomically:true
dict2 := NSDictionary
dictionaryWithContentsOfFile:'/Users/foo/test.plist'
dict2 objectForKey:'a'
dict2 objectForKey:'b'
Both printed out fine. If you take a look at the XML spec, it has this
to say about whitespace:
"An XML processor MUST always pass all characters in a document that
are not markup through to the application. A validating XML processor
MUST also inform the application which of these characters constitute
white space appearing in element content."
So how whitespace is handled is entirely up to the application, it is
illegal for parsers to ignore it. Obviously, Apple has chosen to not
ignore it.
I have no doubt Apple is following the guidelines. The fact is that I'm
looking at a workaround for a funny issue involving a CVS server, where
a '\r' is switched to '\n'.
