JDOM: How to avoid in pretty printed output?

How do I avoid 
 in my XML output?

JDOM talks about this in the javadoc of the method Format.setLineSeparator.

For the sake of this question, please assume that I only get an XML document that I have to serialize. XML element texts might contain any combination of \r, \n and \r\n, from a database, UI component, browser, program, etc.

Is it possible to configure JDOM to only write \r\n, and never 

Is this a specialty of JDOM or do other XML libraries behave the same? Will have to check...

The only idea I have so far is to iterate the complete document and remove any occurence of \r in any text property of any element. If that is indeed my only option, I would also be interested in a correct and readable way of doing so.

Another idea i have is to clean the output: xml.replace("
", "")


  public static void main(String[] args) throws Exception
    JTextPane pane = new JTextPane();
    pane.setText("line 1\r\nline 2");
    //    pane.setText("line 1\nline 2");
    Element element = new Element("el");

    Format format = Format.getPrettyFormat();
    StringWriter writer = new StringWriter();
    new XMLOutputter(format).output(new Document(element), writer);


    <?xml version="1.0" encoding="UTF-8"?>
    <el>line 1&#xD;
    line 2</el>


I ran into this because JTextPane.getText() sometimes returned text with just \n, and sometimes with \r\n. JTextPane also has some pretty crazy end of line logic. See DefaultEditorKit (search for EndOfLineStringProperty).

The documentation you cite is pretty emphatic that the answer here is "no".

Anytime it sees a "\r" in the input string it will replace it with a "&#xD;". Using setLineSeparator just changes what "\n" gets converted to.

What happens if you call: format.setLineSeparator(LineSeparator.NONE);
