Re: XInclude Support

Hi,  My question is specifically on commons-configuration2.

I cannot seem to use XInclude within an XMLConfiguration file.  Perhaps I
am doing something incorrectly, or perhaps it is unsupported, but I can't
seem to find documentation either way.

This is my example program, files and output.

TestConfiguration.java

package test;

import java.io.File;

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 {
        Parameters params = new Parameters();
        FileBasedConfigurationBuilder<XMLConfiguration> builder = new
FileBasedConfigurationBuilder<XMLConfiguration>(
                XMLConfiguration.class);
        builder.configure(params.fileBased().setFile(
                new File("configs/test_external.xml")));
        XMLConfiguration config = builder.getConfiguration();
        System.out.println(ConfigurationUtils.toString(config));
    }
}


configs/test_external.xml

<?xml version="1.0" encoding="UTF-8"?>
<ExternalRoot>
    <ExternalElements>
        <xi:include xmlns:xi="http://www.w3.org/2001/XInclude"
            href="configs/test_internal.xml" />
    </ExternalElements>
</ExternalRoot>


configs/test_internal.xml

<?xml version="1.0" encoding="UTF-8"?>
<InternalRoot>
    <InternalElement name="1" />
    <InternalElement name="2" />
    <InternalElement name="3" />
</InternalRoot>


Result:

ExternalElements.xi:include[@xmlns:xi]=http://www.w3.org/2001/XInclude
ExternalElements.xi:include[@href]=configs/test_internal.xml


Expected Result:

ExternalElements.InternalRoot.InternalElement[@name]=1,2,3


Any help is appreciated!

Thanks,

Re: XInclude Support

Posted by Aaron Gadberry <aa...@gadberry.com>.

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!
