Unwanted Code Indent

Hi,

I'm actually trying to inject Dom in an plugin I made for specific needs, and having an headache an indentation issue.

This is the last version I tried (I've tried in many ways to get the thing working, but nothing I can do)

exec:function(editor){
        
        var selection = editor.getSelection().getNative();
        var div = new CKEDITOR.dom.element('div');
        var hr = new CKEDITOR.dom.element('hr');
        div.addClass('sommaire');
        hr.addClass('saut_de_page');

        if (selection == '' || selection == 'Introduction') {
           div.appendText('Introduction');
           editor.insertElement(div);
        } else {
           div.appendText(selection);
           editor.insertElement(hr);
           editor.insertElement(div);
        }
   }

And for the example, if I append the text 'Introduction' in the Dom élément div, it will show up like this :

<div class="sommaire">
   Introduction</div>

The thing is that don't need this useless indentation. Something like this :

<div class="sommaire">Introduction</div>

Would be perfect.

Could I easily remove this ?

Thanks for helping.
