grab XML from screen

phuiberts

Hello,
I have to following situation where I have a plain HTML file with a FORM (plus statis form details). When the Form submits via POST it will go from my website to third party one and return me an respond.asp file which on the screen appears as XML data. I can save this data manually as a file and parse it to suit my needs and update my database. In other words the request and subsequent processing work I have coded and I am done with that.

Here is my request, I don't want to request the XML manually, save it, and process in 3 steps, I rather schedule a job therefore I need to combine this work. Can I create php-code that will submit my request html form, save the XML automatically(or put it in a php-variable) so that the processing can be automated in 1 step?

Thanks!

made some progress and load my xml data straiight into a variable via file_get_contents() as desired.For testing I had my DOM object reading a XML file, which also works nicely.

Questions: how can I change the DOM to take the variable from the file_get_contents() instead of a file?

Code reading in XML file, which now needs to take a variable
$objDOM = new DOMDocument();
$objDOM->preserveWhiteSpace = FALSE;
//$objDOM->load($request_url);
if(!$objDOM->load($request_url)) {
die("<P>--> Error opening xml file</P>");
}

Code pieces grabbing XML
// submit action to get XML data in to variable
if ($_POST){
echo "<P>User Has submitted the form</P>"; // TODO: Delete this

	$postdata = http_build_query($_POST); //http_build_query &#8212; Generate URL-encoded query string for passing the POST data
	$opts = array('http' =>
		array(
			'method'  => 'POST',
			'header'  => 'Content-type: application/x-www-form-urlencoded',
			'content' => $postdata
		)
	);	
	$context  = stream_context_create($opts);
	$StarCiteOutput = file_get_contents('https://www.seeuthere.com/sut/respond.asp',false,$context);
	echo "<P>My Result: $StarCiteOutput</P>";	// TODO: Delete this	

	// Validate starcite output
	$test = strpos($StarCiteOutput, "sut.respond.error");
	if (strpos($StarCiteOutput, "sut.respond.error") > 0){
		die("<B>Error obtaining XML from StarCite:</B> $StarCiteOutput");
	}
	else {
		//Start Processing the XML result
		require('processing.xml.inc.php');
	}
}
