[jdom-interest] XMLOutputter

[Rolf Lear]

You have a bunch of problems ....

Firstly, white-space in XML has no meaning unless specifically requested
(xml:space="preserve"). Thus, the following two XML documents are
equivalent:
<root><element>text</element></root>
and
<root>
  <element>text</element>
</root>

Secondly, the two documents you have printed in your mail are not
equivalent. The <gui3> element in the first document has no content, but has
<window-manager> in the second. So, your code is not actually adding the
<window-manager> element to the <gui3> element, but to the <linux> element.

As for pretty-printing the XML, try using
  new XMLOutputter("  ",true).outputString(doc)
if you are beta 9 or earlier, and 
  new XMLOutputter(Format.getPrettyFormat()).outputString(doc)
if you are using Beta 10.

Finally, the <?xml version="1.0" encoding="UTF-8"?> line is just fine. Leave
it there!

Hi,

I got a bit of a problem, i'm using XMLOutputter to let my application put
some manipulated XML elements in the output in an XML format. But the
problem is i just get it in 1 line like:

<?xml version="1.0" encoding="UTF-8"?>

<linux><gui3></gui3><window-manager></window
manager><type>java</type><name>Enlightenment</name><version3>0.16.2</version
3><gui></gui><window-manager></window
manager><name>Enlightenment</name><version1>0.16.2</version1></linux>


All info i need is there, but not formatted right... it should be :
<linux>
 <gui3>
    <window-manager>
      <type>java</type>
      <name>Enlightenment</name>
      <version3>0.16.2</version3>
    </window-manager>
  </gui3>
  <gui>
    <window-manager bla="2">
      <name>Enlightenment</name>
      <version1>0.16.2</version1>
    </window-manager>
  </gui>
</linux>


Anyone here know what's wrong?

Thanks, Joachim.
