Get textbox value using PHP

Question

Perhaps someone knows how to get the value of a specific element in an HTML document with PHP? What I'm doing right now is using file_get_contentsto pull the HTML code from another site, and this website has a text box:

<textarea id="body" name="body" rows="12" cols="75" tabindex="1">Hello World!</textarea>

What I want to do is make a script file_get_contentsand just pull out "Hello World!". from the text box. Is it possible? Sorry for listening to you guys again, you are giving such useful advice:].

PHP DOM DOMXPath.

$dom = DOMDocument::loadHTMLFile( $url );
$xpath = new DOMXPath( $dom );
$nodes = $xpath->query('//textarea[id=body]' )

$result = array();
for( $nodes as $node ) {
    $result[] = $node->textContent;
}

$result id.
