[codenameone-discussions] Re: Generate XML file with XMLWriter

[Shai Almog]

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.

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

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 it works.

But how to generate XML file and write tag into with XMLWriter ? 
With my code and toXML() method, that isn't work.

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:
