Hi Matthias,
The problem here is you are saving the /contents/ out via the
PageDocument.Page type, rather than the PageDocument itself.
In 1.0.3 you can get round this two ways: either by calling save on the
document, or pass in XmlOptions.setSaveOuter().
An example never hurt (and I need the practice!). Try this:
import java.io.File;
import java.io.StringWriter;
import org.apache.xmlbeans.XmlOptions;
import com.foo.*;
public class Test {
public static void main(String args[]){
PageDocument page = null;
StringWriter out = new StringWriter();
try{
// Input your example doc:
page = PageDocument.Factory.parse(new File("doc.xml"));
// Change something (add another container):
ContainerType container2 = page.getPage().addNewContainer();
container2.set(page.getPage().getContainerArray(0));
// Output
XmlOptions xmlOptions = new XmlOptions();
xmlOptions.setSavePrettyPrint();
out.append("Oops:\n");
page.getPage().save(out, xmlOptions);
out.append("\n\nFixed:\n");
page.getPage().save(out, xmlOptions);
out.append("\n\nFixedAgain:\n");
page.save(out, xmlOptions);
} catch (Exception e){
e.printStackTrace();
return;
}
System.out.println(out.toString());
}
}
Check out the javadoc for XmlObject where all is explained!
http://xmlbeans.apache.org/docs/1.0.4/reference/index.html
Hmm, seems 1.0.4's out and I didn't notice.
All the best,
Dave.
