Xerces Unmarshaller bug removing single whitespace
Hello ,
When using Xerces (2.9.0 as well as 2.9.1) for unmarshalling it removes
(from line 101:)
<subjectmark><![CDATA[No specific subject]]></subjectmark>
the single whitespace between "specific" and "subject". In the loaded object
the String value " No specificsubject" can be found.
The strange behavior is, that if I enter some linebreaks obove the last
object tag (question) from
</question>
<question>
To
</question>
<question>
the bug does not occur. Also strange is that the same tag (subjectmark) with
the same value occurs many times in the file, but only this one is parsed
wrongly.
My questions are:
1) Does anybody can tell me if I did something wrong?
2) Ist his a bug? Can anybody tell me how to report this bug / in which
component? The bug reporting page is awfully complicated to do so. I only
can read old bug reports but no data entry page can be found.
Many thanks in advance,
Thimo
P.S.: My java code is:
FileInputStream fis = new FileInputStream(aFileToImport); // is attached
file AnonymizedImport.xml
InputStreamReader isr = new InputStreamReader(fis,
Exporter.DEFAULT_ENCODING); // means UTF8
Unmarshaller tempUnmarshaller = new Unmarshaller();
Mapping tempMapping = new Mapping();
tempMapping.loadMapping(Exporter.class.getClassLoader().getResource(Exporter
.XML_MAPPING_FILE)); // see attached file import.xml
tempUnmarshaller.setMapping(tempMapping);
tempUnmarshaller.setDebug(stdlog.isDebugEnabled());
ImportExportBean tempImportBean = (ImportExportBean)
tempUnmarshaller.unmarshal(isr);

Hello Michaek,
Thanks a lot for your answer. You´re right (sorry for that). I use
Castor-XML for unmarshalling.
And there was the problem: I just tried an older xerces version and
everything was OK. But now I checked a newer Castor and everything is OK,
too.
-> It was a incompatibility between my old Castor and the new Xerces.
Thanks,
Thimo

Betreff: Re: Xerces Unmarshaller bug removing single whitespace
Hi Thimo,
There's no such thing as a "Xerces Unmarshaller" so have no idea what
library you're referring to but it certainly doesn't come from this
project. I doubt this is a problem with Xerces. I suspect the Unmarshaller
classes you're using are the source of the odd behaviour possibly because
it's not handling multiple calls to the SAX characters() callback [1]
correctly.
A ContentHandler written like:
private StringBuffer buf;
public void characters(char[] ch, int start, int length)
throws SAXException {
buf.append(new String(ch, start, length).trim());
}
would cause whitespace to be dropped from seemingly random points in the
document (like you're seeing).
Thanks.
