How should I deal with linebreaks in strings I want to marshal in Java to XML? -

how should deal linebreaks in strings want marshal xml?

i having difficulty using java , jaxb handle putting strings in xml files have linefeeds in them. data being pulled database actual line feed characters in them.

foo <lf> bar 

or additional example:

foo\r\n\r\nbar 

yields:

foo
 
 bar 

if marshal data xml, literal line feed characters in output. apparently against xml standards characters should encoded 
. ie in xml file output should see:

foo 
bar

but if try , manually, end ampersand getting encoded!

foo 
bar

this pretty ironic because process apparently supposed encode linebreaks in first place , not, foiling attempts encode manually.

below example of jaxb's default behaviour regarding \n , \r:

java model (root)

import javax.xml.bind.annotation.xmlrootelement;  @xmlrootelement public class root {      private string foo;     private string bar;      public string getfoo() {         return foo;     }      public void setfoo(string foo) {         this.foo = foo;     }      public string getbar() {         return bar;     }      public void setbar(string bar) {         this.bar = bar;     }  } 

demo code

import javax.xml.bind.*;  public class demo {      public static void main(string[] args) throws exception {         jaxbcontext jc = jaxbcontext.newinstance(root.class);          root root = new root();         root.setfoo("hello\rworld");         root.setbar("hello\nworld");          marshaller marshaller = jc.createmarshaller();         marshaller.marshal(root, system.out);     }  } 

output

<?xml version="1.0" encoding="utf-8" standalone="yes"?><root><bar>hello world</bar><foo>hello&#xd;world</foo></root>

update

below additional details based on investigation did.

common jaxb (jsr-222) implementations

• if marshalling xmlstreamwriter or xmleventwriter directly (via marshaller) or indirectly (via potentially jax-rs or jax-ws provider) escaping based on stax implementation. woodstox appears escape things correctly, stax implementation in jdk i'm using did not.

eclipselink jaxb (moxy)

• there bug in moxy related escaping \r in process of fixing (see: http://bugs.eclipse.org/414608)

jaxb reference implementation

• the jaxb reference implementation escape '\r' when marshalling outputstream, not writer atleast in jdk i'm using.
