escaping chars in XSD [message #77722]

hi XSD

Do you have any built-in chars escaping that could change '\r' to
'' in my XSD documents? I'm doing some operations on XSD model and
it's underlying DOM, and suddenly get \r chars escaped.

Because it's not only EMF-XSD involved, I'm a bit puzzled and trying to
figure out who is doing this "favour" to me :-)

thanks a lot for your help

No, all the work is done by the doSerialize methods in XSDResourceImpl:

try
{
Transformer transformer = new
DefaultJAXPConfiguration().createTransformer(encoding);
// Be sure to use actual encoding of the transformer which might
be non-null even if encoding started as null.
encoding = transformer.getOutputProperty(OutputKeys.ENCODING);
Writer writer = encoding == null ? new
OutputStreamWriter(outputStream) : new OutputStreamWriter(outputStream,
encoding);
transformer.transform(new DOMSource(element), new
StreamResult(writer));
}
catch (TransformerException exception)
{
XSDPlugin.INSTANCE.log(exception);
}

I'd have to assume it's the underlying JAXP implementation. Keep in
mind that when reading documents, JAXP normalizes the platform specific
linefeed convention to \n regardless of the platform, so when
serializing, it expects to see \n while \r will be considered a special
character that needs escaping. So probably your application should be
using \n exclusively to avoid any \r in the output...
