[mali djuro]

Hi all,
i try to make xml file with jdom, and also i made xsl file for presenting
xml in browser.
because of that i need to add processing instuction in xml file
....
<?xml-stylesheet type="text/xml" href="test.xsl" ?>
<root>
....
</root>

i did :

Element root = new Element("root");
Document document = new Document(root);

ProcessingInstruction pi = new ProcessingInstruction("xml-stylesheet",
"type='text/xsl' href='test.xsl'");

document.addContent(pi);

....

i got xml file like this

<?xml version=1.0 ?>
<root>
....
</root>
<?xml-stylesheet type="text/xsl" href="test.xsl" ?>

how to put this line
<?xml-stylesheet type="text/xsl" href="test.xsl" ?>
in front of <root>

Hi,
I don't know If you find your answer... If you don't, I've found it :)
you must create an empty document like :

Document doc = new Document();

then add your ProcessingInstruction to this empty document
like doc.addContent(pi);

and finally set the root element of the document :
doc.setRootElement(root);

And know you have the processing instruction in front of the root Element.
