Alex-
Here's the mapping file:
<mapping>
<class name="NodeClass">
<map-to xml="node-class" />
<field name="xml" type="org.w3c.dom.Node" direct="true"
handler="DOMHandler">
<bind-xml name="description" node="element" />
</field>
</class>
</mapping>
And here is the DOMHandler class, with exception handling removed
(please excuse the poor variable names):
public class DOMHandler extends GeneralizedFieldHandler {
public Object convertUponGet( Object arg0 ) {
// take in object, return string
Node xml = (Node)arg0;
Transformer t = TransformerFactory.newInstance().newTransformer();
Source input = new DOMSource( xml );
StringWriter sw = new StringWriter();
Result output = new StreamResult( sw );
t.transform( input, output );
return( sw.getBuffer().toString() );
}
public Object convertUponSet( Object arg0 ) {
// take in string, return object
DocumentBuilder db =
DocumentBuilderFactory.newInstance().newDocumentBuilder();
StringReader input = new StringReader( (String)arg0 );
Node xml = db.parse( new InputSource( input ) );
return( xml );
}
public Class getFieldType() {
return( Node.class );
}
}
That should give you everything you need to get the functionality I
achieved. Let me know if you have any problems.

Subject: Re: [castor-user] JDOM/DOM Node as Field?
Alex-
I did some quick tests this morning, and using a CustomFieldHandler
(http://castor.codehaus.org/xml-fieldhandlers.html) I was able to
"marshal" and "unmarshal" a DOM node, but as has been discussed on the
list before, Castor performs entity replacement (lots of > <) so
it doesn't look exactly how one would expect. I haven't been following
the arbitrary XML discussion very closely, but that may be the larger
challenge in this case.
Actually, this might help. In reality, the server isn't going
to do much with this XML. Just store it in the database as a blob
and then needs to reconstitute it on the way out as proper XML.
Can you send me this example? I'd like to try some experiments. :)
Thanks!
