Hello!
When I save resource using Default XML serialization and in that
resource some element with value e.g. "Hello\r\nWorld!" is contained, I
get XML like that: "Hello
\r\n". I know that 
 is XML entity
representin Unicode character for CR, but why it's saved twice as xml
entity and as '\r' char? Can you clarify this point: how actually save
CR character correctly?
Thank you,
Alexey

Well yes. Tom already mentioned that and why. If it didn't do that,
what you'd get back when reading it would be the value "Hello\nWorld"
because any XML parser will convert the system's line feed convention to
"\n". The serializer is written so it preserves *exactly *the sequence
of characters you specified. (I thought when you said \r\n you
literally meant those two letter escape sequence appeared in the XML file...

I think if you see \r or \n in the serialization it's because you have
the two characters \ followed r or n in the string itself. I can't
imagine that serialization would ever convert a character into a Java
escape sequence. Some other aspect of the logic (not the serialization
log) must be doing that...

Ed, what do mean by 'some other aspect of the logic must be doing
that'?
<br>
My code is:
<br>
<br>
EObject config = EcoreUtil.create(someClass);
<br>
config .eSet(ref, "Hello\r\nWorld");
<br>
<br>
Resource resource = ;
<br>
resource .getContents().add(config);
<br>
<br>
ByteArrayOutputStream os = new ByteArrayOutputStream();
<br>
resource.save(os, null);
<br>
assertEquals("Hello&#xD;\r\nWorld", os.toString());
<br>
<br>
So I think it is XMLResourceImpl that convert \r to &#xD;

I imagine the reason the \r still shows up is because the save()
function will turn \n into the current platform's new line characters,
which on windows is \r\n.
So first it was turned into "
\n" by the XML serialization and then
the function turned that last remaining \n into \r\n because that is the
current platform's new line characters.
