Call CKEditor by class

I need to call multiple instances of CKEditor automatically...actually I use the function:

CKEDITOR.replace( 'editor1');

Where "editor1" is the id name of the div where I want show my CKEditor.

I'm using jQuery to automate this process and I need to use the "class" tag instead the id.

In particular i have this html:

<div class="CKEditor">
    <div class="text">
            mytext
    </div>

    <p style="text-align:center" class="buttons">
        <input type="button" value="edit" class="button_edit">
        <input type="button" value="preview" class="button_preview" style="display:none">
    </p>

    <div class="editor" >
    </div>

</div>

and this jQuery script:

$(function() 
{
    $('.CKEditor').each(function()
    {
        var __main = $(this);
        var __buttons = __main.children('.buttons');
        var __text = __main.children(".text");
        var editor;

        __buttons.children('.button_edit').click(function()
        { 
            __text.hide();
            if (editor) return;

            editor = CKEDITOR.replace("editor");
            editor.setData(__text.html());

            if(editor)
            { 
                __buttons.children('.button_edit').hide(); 
                __buttons.children('.button_preview').show(); 
            }
        });

        __buttons.children('.button_preview').click(function()
        {
            __text.show();
            __text.html(editor.getData());

            if ( !editor ) return;

            editor.destroy();
            editor = null;
            __buttons.children('.button_edit').show(); 
            __buttons.children('.button_preview').hide(); 
            __main.children("#editor").html("");
        });
    });
});

Is it possible without modify the source of CKEDITOR?
