[jdom-interest] Bug in SAXBuilder for mixed content

Of the four documents (below), I think the first two have correct output,
but 3 and 4 do not. I would gues the problem is in SAXBuilder, which counts
me out for offering a quick fix, as I know nothing about SAX. Calling
getChild("c") on the elements throws a NoSuchElementException for documents
3 and 4. (I'm using the June5 source.)
The following code...
public class JDOMTest {
public static void main(String[] args) throws Exception {
checkMixedContent("<nomix><c>c1</c><c>c2</c></nomix>");
checkMixedContent("<mix><c>c1</c><!-- comment --></mix>");
checkMixedContent("<mix><c>c1</c>m2</mix>");
checkMixedContent("<mix>m1<c>c1</c>m2</mix>");
}
public static void checkMixedContent(String xml) throws Exception {
System.out.println(xml);
org.jdom.Document document = new org.jdom.input.SAXBuilder().build(
new java.io.StringReader(xml) );
org.jdom.Element element = document.getRootElement();
System.out.println("\thasMixedContent:\t" + element.hasMixedContent());
System.out.println("\tgetContent: \t\t" + element.getContent());
System.out.println("\tgetChildren: \t\t" + element.getChildren());
//System.out.println("\tgetChild(c): \t\t" + element.getChild("c"));
System.out.println("\tgetMixedContent:\t" + element.getMixedContent());
}
}
Produces ...
<nomix><c>c1</c><c>c2</c></nomix>
hasMixedContent: false
getContent:
getChildren: [[Element: <c />], [Element: <c />]]
getMixedContent: [[Element: <c />], [Element: <c />]]
<mix><c>c1</c><!-- comment --></mix>
hasMixedContent: true
getContent:
getChildren: [[Element: <c />]]
getMixedContent: [[Element: <c />], [Comment: <!-- comment
-->]]
<mix><c>c1</c>m2</mix>
hasMixedContent: false
getContent: m2
getChildren: []
getMixedContent: [m2]
<mix>m1<c>c1</c>m2</mix>
hasMixedContent: false
getContent: m1m2
getChildren: []
getMixedContent: [m1m2]

Hi all,
=20
After generating a jdom Document from some stream you'd might like to =
write
the result into another stream.
In the result file, all =FC characters were converted into =C2=BC.
I could only get this working by removing the encoding in
XMLPutter.output().
=20
I'm now using these parameter signatures:
=20
public void output(Document doc, OutputStream out) throws IOException; =
// No
encoding
public void output(Document doc, OutputStream out, String enc) throws
IOException;
=20
It would be nice seeing this feature in the upcoming release (unless =
the
problem may be solved in another way).
=20
Cheers,
