A Document node may not be the child of any other node, I think. You need
to add the root element of the document to the new document, something like
this:
newNode =
newDoc.importNode(res.getContentAsDOM().getDocumentElement(),
true);

Subject: Re: Problem with adding DOM node from getContentAsDOM() to other
DOM
It seems that even this solution throws and error when you attempt
importNode. It seems the type returned by getContentAsDOM method is
org.apache.xindice.xml.dom.DocumentImpl. The JavaDoc claims the should
return type org.w3c.dom.Node.
The DocumentImpl is a type Node, but does seem that it can be inserted
into another DOM document.
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
...
import org.xmldb.api.base.*;
import org.xmldb.api.modules.*;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.xmldb.api.*;
public class Example2 {
public static void main(String[] args) throws Exception {
Collection col = null;
try {
String driver = "org.apache.xindice.client.xmldb.DatabaseImpl";
Class c = Class.forName(driver);
Database database = (Database) c.newInstance();
DatabaseManager.registerDatabase(database);
col =
DatabaseManager.getCollection("xmldb:xindice:///db/Classifieds");
String xpath = "//[EMAIL PROTECTED]'105' or @id='100' or
@id='500']";
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document newDoc = builder.newDocument();
//Document doc;
Element root = newDoc.createElement("Results");
newDoc.appendChild(root);
XPathQueryService service =
(XPathQueryService) col.getService("XPathQueryService",
"1.0");
ResourceSet resultSet = service.query(xpath);
ResourceIterator results = resultSet.getIterator();
Node newNode;
while (results.hasMoreResources()) {
XMLResource res = (XMLResource)results.nextResource();
newNode = newDoc.importNode(res.getContentAsDOM(), true);
root.appendChild(newNode);
}
System.out.println(newDoc.toString());
}
catch (XMLDBException e) {
System.err.println("XML:DB Exception occured " + e.errorCode);
}
finally {
if (col != null) {
col.close();
}
}
}
}
Please let me know if their is a better way to handle these issues.
Cheers,
Evan
