Elliotte Rusty Harold resolved XERCESJ-766.
-------------------------------------------
Resolution: Not A Bug
When indenting is turned on white space is changed. That's expected. To
preserve whitespace, don't tell the serializer to change whitespace.
> unauthorized handling of whitespace when prettyprinting mixed content

> Key: XERCESJ-766
> URL: https://issues.apache.org/jira/browse/XERCESJ-766
> Project: Xerces2-J
> Issue Type: Bug
> Components: Serialization
> Affects Versions: 2.4.0
> Environment: Operating System: Linux
> Platform: PC
> Reporter: Holger Klawitter
>
> The serializer has problems when dealing with mixed content elements:
> Sometimes additional whitespace gets inserted, sometimes whitespace
> gets ignored:
> {noformat}
> public class TestXerces {
> public static void main( String[] args ) throws Exception {
> String inputXML =

> "<!DOCTYPE DOC [\n"+

> OutputFormat format = new OutputFormat("xml", "ISO-8859-15", false);
> format.setIndenting(true);
> format.setIndent( 2 );
> format.setLineWidth( 65000 );

> {noformat}
> This results in:
> <?xml version="1.0" encoding="ISO-8859-15"?>
> <!DOCTYPE DOC [<!ELEMENT DOC (P)*>
> <!ELEMENT B (#PCDATA)>
> <!ELEMENT P (#PCDATA|B|P)*>

> I also got another case (however it didn't reproduce) where
> aaa<B>bbb</B> & xxx
> became
