Well, my previous comment won't work in this case, I'll leave it for info though...

Another approach is to clean it up before parsing it with simple_html_dom using Tidy extension. But it seems not to be working here either...

A last approach I can think of, and if this is your only problematic case, is to use regex to get what you want:

Using <textarea.*?name="xxx".*?id="xxx".*?\/>([^<]+)<\/textarea> ==> RegEx DEMO

The output will be in group one of the resulting array $match. Check this working code:

$input =  <<<_DATA_ 
<textarea name="xxx" id="xxx" />this is value</textarea>
_DATA_;

$pattern = '/<textarea.*?name="xxx".*?id="xxx".*?\/>([^<]+)<\/textarea>/';

preg_match($pattern, $input, $match);
var_dump($match)

It is easy to get the value of a Teaxtarea in javascript:

 <script type=text/javascript>

function getValueTextarea()
{
   var vl=document.getElementById("tx").value;
   alert(vl);
}

</script>

<body>
   <textarea id="tx">Value Of Textarea</textarea>
   <input id="button" value="Get Value" onclick="getValueTextarea()">  
</body>
