Re: Importing and Exporting XML

[woolly]

Hi there,

I've got a hold of DocumentViewExportVisitor from the contrib section as
suggested, and added the jar files xercesImpl-2.8.1.jar and
commons-codec-1.3.jar that it appeared to require. I then subclassed
DocumentViewExportVisitor like this:

public class CleanDocumentViewExportVisitor extends
DocumentViewExportVisitor
{
        
        public CleanDocumentViewExportVisitor(ContentHandler handler, boolean
skipBinary, boolean noRecurse)
        {
                super(handler, skipBinary, noRecurse);
        }
        
        @Override
        protected boolean includeProperty(Property property) throws
RepositoryException
        {
                return !property.getName().startsWith("jcr:");
        }
}

.....and exported my document using this:

SAXTransformerFactory factory = (SAXTransformerFactory)
SAXTransformerFactory.newInstance();
TransformerHandler handler = factory.newTransformerHandler();
handler.setResult(new StreamResult(output));
node.accept(new CleanDocumentViewExportVisitor(handler, skipBinary,
noRecurse));

....but I end up with the following (based on my original <cheeses>
example):

<?xml version="1.0" encoding="UTF-8"?>
<cheeses xmlns:dc="http://www.purl.org/dc/elements/1.1/";
xmlns:jcr="http://www.jcp.org/jcr/1.0";
xmlns:nt="http://www.jcp.org/jcr/nt/1.0";
xmlns:sv="http://www.jcp.org/jcr/sv/1.0";
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:fn="http://www.w3.org/2005/xpath-functions";
xmlns:fn_old="http://www.w3.org/2004/10/xpath-functions";
xmlns:mix="http://www.jcp.org/jcr/mix/1.0"; xmlns:rep="internal">
    <cheese>edam</cheese>
    <cheese>lancashire</cheese>
    <cheese>cheshire</cheese>
    <cheese>stilton</cheese>
</cheeses>

Why does JCR need to add all these namespaces to my root node on export?
They're not shown as properties when they are stored in the repository, and
I can't affect them as they are never passed through includeProperty().

Thanks

Phil.
