Description:
------------
I know there's no such attribute value="" but you can't access the content ($textarea->textContent will not work as well) of that if the content inside is wrapped within "lt" and "gt" <textarea><won't read></textarea> (ie when you read embed tags from textarea)

Reproduce code:
---------------
$documentx = new DOMDocument();
$documentx->loadHTML($data);
$textareas = $documentx->getElementsByTagName("textarea");
foreach($textareas AS $textarea){
   print($textarea->getAttribute("value"));
}




<textarea><img src="foobar" /></textarea>

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

If there's no attribute "value" then there's nothing to print then 
there's no output.

  print $textarea->nodeName;

instead of

  print $textarea->getAttribute("value");

does produced some expected thing.

I can't understand what "expected thing" should be.
I agree that the dom parser sees the textarea,
but if the textarea content is wrapped within < and > there is no way to read its content.

<textarea><img src="foobar" /></textarea>

In javascript if you set the value of a textarea to be "xxx" it's filled correctly even if the attribute value does not exists in the textarea tag


thank you for your time

this should help to understand, in Javascript you can access this strange attribute

<textarea id="pippo"></textarea>

<script>
document.getElementById('pippo').value = "<embed embed>";
alert(document.getElementById('pippo').value);
</script>

this work as expected, in php you can't do that.

(i know that javascript is a client side script, I use it just as an example of a DOM abstraction)
