Hi,
To answer my own question, the document builder I was using was not
namespace or xinclude aware. Acquiring a document builder manually and
setting a custom document builder on the XMLConfiguration allowed XInclude
to function as intended.
Here is the updated and functional code and output.
package test;
import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.apache.commons.configuration2.ConfigurationUtils;
import org.apache.commons.configuration2.XMLConfiguration;
import
org.apache.commons.configuration2.builder.FileBasedConfigurationBuilder;
import org.apache.commons.configuration2.builder.fluent.Parameters;
import org.apache.commons.configuration2.ex.ConfigurationException;
public class TestConfiguration {
public static void main(String[] args) throws ConfigurationException {
try {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setXIncludeAware(true);
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Parameters params = new Parameters();
FileBasedConfigurationBuilder<XMLConfiguration> builder = new
FileBasedConfigurationBuilder<XMLConfiguration>(
XMLConfiguration.class);
builder.configure(params.xml()
.setFile(new File("configs/test_external.xml"))
.setDocumentBuilder(db));
XMLConfiguration config = builder.getConfiguration();
System.out.println(ConfigurationUtils.toString(config));
} catch (ParserConfigurationException e) {
e.printStackTrace();
}
}
}
New Output:
[@xmlns:xi]=http://www.w3.org/2001/XInclude
ExternalElements.InternalRoot[@xml:base]=test_internal.xml
ExternalElements.InternalRoot.InternalElement[@name]=[1, 2, 3]
Thanks!
