JAXB: How to ignore namespace during unmarshalling XML document?
java, jaxb, xml, xml-serialization
Solution
I believe you must add the namespace to your xml document, with, for example, the use of a SAX filter.
That means:
- Define a ContentHandler interface with a new class which will intercept SAX events before JAXB can get them.
- Define a XMLReader which will set the content handler
then link the two together:
public static Object unmarshallWithFilter(Unmarshaller unmarshaller,
java.io.File source) throws FileNotFoundException, JAXBException
{
FileReader fr = null;
try {
fr = new FileReader(source);
XMLReader reader = new NamespaceFilterXMLReader();
InputSource is = new InputSource(fr);
SAXSource ss = new SAXSource(reader, is);
return unmarshaller.unmarshal(ss);
} catch (SAXException e) {
//not technically a jaxb exception, but close enough
throw new JAXBException(e);
} catch (ParserConfigurationException e) {
//not technically a jaxb exception, but close enough
throw new JAXBException(e);
} finally {
FileUtil.close(fr); //replace with this some safe close method you have
}
}
Problem
My schema specifies a namespace, but the documents don't. What's the simplest way to ignore namespace during JAXB unmarshalling (XML -> object)? In other words, I have ``` <foo><bar></bar></foo> ``` instead of, ``` <foo xmlns="http://tempuri.org/"><bar></bar></foo> ```
