Generate XML file with XMLWriter

[pyth...@gmail.com]

Hi,

I have some problems to generate an XML file, the file is created but the root tag is not written into the file when I call the writeXML(writer, root) method;

Here is the code :

try{
        //Element root
        Element root = new Element("root");
        String path = FileSystemStorage.getInstance().getAppHomePath();
        XMLWriter xw = new XMLWriter(false);    
        OutputStream os = FileSystemStorage.getInstance().openOutputStream(path+""+"test.xml");   
        OutputStreamWriter writer = new OutputStreamWriter(os);
        xw.writeXML(writer, root);
        os.close();
        writer.close();

}catch(....){

   .....

}

Any idea ?

Thank you.

I just tried this:

Form hi = new Form("XML", BoxLayout.y());
Button write = new Button("Write");
hi.add(write);
write.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent evt) {

        Element root = new Element("root");

        XMLWriter xw = new XMLWriter(false);

   
        Log.p(xw.toXML(root));
    }
});

hi.show();

It printed out:

 <root />

Yes it works.

But how to generate XML file and write tag into with XMLWriter ?

With my code and toXML() method, that isn't work.

Both methods lead to the same block: https://github.com/codenameone/CodenameOne/blob/master/CodenameOne/src/com/codename1/xml/XMLWriter.java#L180-L242

I'm guessing the problem you are experiencing is in reading the XML.

Yes, I want to create an XML file and save it to the phone. For the moment, it is saved in the .cn/ repertory of my PC and when I open it for check, it is empty and no tag is there

Try this:

                try(OutputStream os = FileSystemStorage.getInstance().openOutputStream(path+""+"test.xml");  OutputStreamWriter writer = new OutputStreamWriter(os)) {
                    xw.writeXML(writer, root);
                    writer.close();
                } catch(IOException err) {
                    Log.e(err);
                }

It looks like your code closes the output stream instead of the writer. This can discard unflushed bytes.
