<?xml version="1.0" encoding="UTF-8"?>
<form>
<fieldset addfieldpath="/administrator/components/com_categories/models/fields" >
<field
type="editor"
name="myEditorField"
id="myEditorField"
label="MY EDITOR FIELD LABEL"
description="MY EDITOR FIELD DESCRIPTION"
width= "99%"
rows="5"
editor="desired|alternative"
cols="200"
buttons="true"/>
<field name="articletext" type="editor" class="inputbox"
label="COM_CONTENT_FIELD_ARTICLETEXT_LABEL" description="COM_CONTENT_FIELD_ARTICLETEXT_DESC"
filter="JComponentHelper::filterText" buttons="true" />
</fieldset>
</form>
save above code in editor.xml and use following php code to display editor
<?php
$mypath= JPATH_COMPONENT.'/views/' .'createTask'. '/tmpl/editor.xml';
$form = JForm::getInstance('myform',$mypath );
echo $form->getInput('myEditorField');
?>
follwoing code will echo javascript to set editor content
$editor =JFactory::getEditor();
$setContent=$editor->setContent($name,'hello');
$js1 = 'function setEditorText (){return '.$setContent.'}';
$doc= JFactory::getDocument();
$doc->addScriptDeclaration($js1);

Other way to get and set content in JOOMLA editor is use following js.
Wrap your editor in div having class .myPreviewEditor
to set content
$('.myPreviewEditor iframe').contents().find('body').html("i am in editor");
to get content
$editoContent=$('.myPreviewEditor iframe').contents().find('body').html();
but make sure that these statement execute after JOOMLA editor loads itself
