Thanks Volker!
Indeed you're right, my DTD was wrong.
http://www.w3.org/TR/REC-xml#NT-Mixed
I should not trust Wrox books (or french translations, I don't know...) from
which the example was extracted..
By the way, could you explain me please the difference between
xercesImpl.jar and xml-apis.jar.
My self experience:
import org.apache.xerces.parsers.DOMParser;
import org.w3c.dom.Document;
import org.xml.sax.SAXException;
import java.io.IOException;
public class DOMParserDemo2 {
public static void main (String args[]){
DOMParser parser = new DOMParser();
Document doc = null;
try {
parser.parse("CatalogueLivres.xml");
doc = parser.getDocument();
} catch (IOException ie){
System.out.println("Could not read file.");
} catch (SAXException e) {
System.out.print("Could not create Document: ");
System.out.println(e.getMessage());
}
}
}
will compile well with xercesImpl.jar in classpath but will throw an
exception at runtime:
java.lang.NoClassDefFoundError: org/w3c/dom/range/DocumentRange
All compiles and runs well with xml-apis.jar on my classpath.
why this happens?
I would be very grateful if you may shed light on this topic..
Regards,
Cyril.
