Re: [basex-talk] xmldb api and namespace handling

Hi Frans,

the following code with the newest release of BaseX produces correct results:

package org.basex.examples.xmldb;

import org.basex.api.xmldb.BXCollection; import org.xmldb.api.base.*; import org.xmldb.api.modules.XMLResource; import org.xmldb.api.*;

/** * This class serves as an example for creating a database with the XML:DB API. * * @author BaseX Team 2005-11, BSD License */ public final class Test { /** Database driver. */ public static final String DRIVER = "org.basex.api.xmldb.BXDatabase";

/** * Main method of the example class. * @param args (ignored) command-line arguments * @throws Exception exception */ public static void main(final String[] args) throws Exception {

System.out.println("=== XMLDBCreate ===");

try { // Register the database Class<?> c = Class.forName(DRIVER); Database db = (Database) c.newInstance(); DatabaseManager.registerDatabase(db);

System.out.println("\n* Create a new collection.");

// Create a new collection BXCollection col = new BXCollection("Collection", false);

// ID for the first document String id1 = "doc1"; // Content of the first document String doc1 = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>" + "<tag xmlns="http://example.org%5C%22%3E" + "</tag>";

// ID for the second document String id2 = "doc2"; // Content of the second document String doc2 = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>" + "<tns:tag xmlns:tns="http://example.org%5C%22%3E" + "</tns:tag>";

System.out.println("\n* Create new resources.");

// Create a new XML resource with the specified ID XMLResource res1 = col.createResource(id1, XMLResource.RESOURCE_TYPE); XMLResource res2 = col.createResource(id2, XMLResource.RESOURCE_TYPE);

// Set the content of the XML resource as the document res1.setContent(doc1); res2.setContent(doc2);

System.out.println("\n* Store new resource.");

// Store the resource into the database col.storeResource(res1); col.storeResource(res2);

col.close();

} catch(final XMLDBException ex) { // Handle exceptions System.err.println("XML:DB Exception occured " + ex.errorCode); } } }

Hi Frans,

I'am accessing BaseX 6.5.1 through the XMLDB API. There are some issues with namespace handling when storing resources. Let me clarify that with some examples.

First example

I want to store the following as a resource:

String example = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>" + "<tag xmlns="http://example.org%5C%22%3E" + "</tag>";

This yields <tag xmlns="http://example.org"/> in the GUI. So this is OK.

Second example

I want to store the following as a resource and INTPARSE = false:

String example = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>" + "<tns:tag xmlns:tns="http://example.org%5C%22%3E" + "</tns:tag>";

This yields the following exception: org.xmldb.api.base.XMLDBException: "null" (Line 1): The prefix "tns" for element "tns:tag" is not bound

Third example

I want to store the following as a resource and INTPARSE = true:

String example = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>" + "<tns:tag xmlns:tns="http://example.org%5C%22%3E" + "</tns:tag>";

This yields <tns:tag xmlnstns="http://example.org%22/%3E in the GUI. The colon is missing in ' xmlnstns' . So this is not OK.

Are the second and third examples bugs or should I change some setting to get a proper handling of namespaces?
