pass an xml as a parameter

[maisonsakamoto]

I need to pass an xml as a parameter, I can do something like:

$client = new Client("http://{$this->jasperServerIp}/jasperserver", "jasperadmin", $this->jasperServerPassword);
$uri = $obj->ireport; 
$format = 'pdf'; 
$page = null; 
$attach = null;
$param = array( 'xml_data' => $xmlContent);
$client->reportService()->runReport($uri, $format, $page, $attach, $param);

How would I receive the xml file nodes in the jrxml file? Is there something ready to do this?
