[jira] Commented: (XALANJ-2075) Transformation using StreamResult and DOMSource with text nodes containing "\r\n" results in "
\r\n"
[ http://issues.apache.org/jira/browse/XALANJ-2075?page=comments#action_60249 ]
Brian Minchau commented on XALANJ-2075:
---------------------------------------
Tim,
when the serializer gets \r\n as something it needs to write out it does two things.
The \n is turned into the end of line sequence. This could change in the future, but if you look at the serializer code it calls System.getProperty("line.separator"), and what ever that returns, is what it writes out rather than \n to a flat XML file. I mean XML file here, not a document. An XML file is a sequence of characters.
The \r is written out as to a flat XML file. This is so that when an XML parser reads this file back in it is turned into a \r again, with no distortion of information, otherwise it might accidentally be normalized way
( see http://www.w3.org/TR/REC-xml#sec-line-ends ).
So in your case \r is turned into and \n is turned into \r\n on Windows.
If you feed the serializer \r it will be turned into . Though not an official API on the Xalan serialzier, you could call System.setProperty("line.separator","\n"); to alter what the serializer will pick up from that property.
Sending output to a DOM is completely different, all of these character changes on output are when writing to a flat file.
I'm afraid the serializer is working as designed.
