I have created a custom WYSIWYG editor for editing an XML file. I have used an <iframe> for this.
I have parsed the XML file and all the contents in a variable. How can I place this content in the <iframe>?
I tried this code but it is not working:

<iframe id="textbox"  style="width:300px; height:150px" >
     <?php echo $content ?>
</iframe>

Önceden this.Thanks için kendi herhangi bir javascript kodu.
