DOM TextArea (and dom chart please)

Hey!
i'm just starting with PHP's DOM-XML and need a little help please.


Basically, first i am trying to see if a input like a textbox has a 'VALUE=' associated with it, if yes, i leave it be, if no, i add a default value.

This *is working* as can be seen by the attached code below.

But a bit confused as to how to do the same for a textarea as textarea's do not have a 'VALUE=' attribute.

Heres my code:


$website_data = file_get_contents('dom_test.html');//load the website data,

$dom = new DomDocument; //make a new DOM container in PHP
$dom->loadHTML($website_data);  //load all the fetched data into the DOM container

$inputs = $dom->getElementsByTagName('input'); // Find Sections 

foreach ($inputs as $input) { //***  this block has the guts of the functionality ***
        if(!$input->getAttribute("value") || $input->getAttribute("value")=="") {
                $input->setAttribute("value", "RRRRRRR");
        }
}



// ***** now we come to the textarea bit that is not working *****

$inputs2 = $dom->getElementsByTagName('textarea'); // Find textareas 

foreach ($inputs2 as $input2) {
        if(!$input2->firstChild.nodeValue=="") {
                $input2->firstChild.nodeValue=="it works!";
        }
}



echo $dom->saveHTML();
?>

+++++++++++++++++++++++++++++++

// I have even tried this instead of the above:

foreach ($inputs2 as $input2) {
        if(!$input2->getAttribute("defaultValue")=="") {
                $input2->setAttribute("defaultValue","it works!");
        }
}

but no joy.

I'm betting its pretty simple but i dont have a "DOM chart" for php, the only ones i have been able to find via google are for javascript like this one: http://www.hscripts.com/tutorials/javascript/dom/textarea-events.php


and that chart does not help much.  Does anyone have a PHP DOM chart or a resource that i can use to get started using this?

Thanks in advance!
Ryan
