Examples of org.xmldb.api.modules.XMLResource

org.xmldb.api.modules.XMLResource
Provides access to XML resources stored in the database. An XMLResource can be accessed either as text XML or via the DOM or SAX APIs.
The default behavior for getContent and setContent is to work with XML data as text so these methods work on String content. I.e. it is always possible to do the following
if (resource instanceof XMLResource) { String foo = (String)resource.getContent(); }

        set.setAttribute("xmlns:xapi", RESOURCE_SET_NS);
        doc.appendChild(set);


        int i = 0;
        while (i < resources.size()) {
            XMLResource res = (XMLResource) resources.get(i);
            Element resource = doc.createElementNS(RESOURCE_SET_NS,
                                                   "xapi:resource");
            resource.setAttributeNS(RESOURCE_SET_NS, "xapi:documentID",
                                    res.getDocumentId());


            resource.appendChild(doc.importNode(
                    ((Document) res.getContentAsDOM()).getDocumentElement(), true));


            set.appendChild(resource);


            i++;
        }
