XML and webservice

Need a script to generate a XML that is the input for a webservice. Webservice answer is a XML node. This is part of the code. $process = curl_init('send PM to know details'); curl_setopt($process, CURLOPT_SSL_VERIFYPEER, FALSE); //curl_setopt($process, CURLOPT_CAPATH, capath); curl_setopt($process, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($process, CURLOPT_HTTPHEADER, array('Content-Type: text/xml', 'charset=utf-8')); curl_setopt($process, CURLOPT_POSTFIELDS, $xml); curl_setopt($process, CURLOPT_SSLCERT, '[login to view URL]'); curl_setopt($process, CURLOPT_RETURNTRANSFER, true); curl_setopt($process, CURLOPT_POST, true); $return = curl_exec($process); curl_close($process); $SendPM = substr($return, (strrpos($return, "Send PM") + 10), ((strrpos($return, "Send PM") - 2) - (strrpos($return, "SendPM") + 10))); $SendPM = substr($return, (strrpos($return, "SendPM") + 18), ((strrpos($return, "SendPM") - 2) - (strrpos($return, "SendPM") + 18))); $SendPM = substr($return, (strrpos($return, "SendPM") + 10), ((strrpos($return, "SendPM") - 2) - (strrpos($return, "selloCFD") + 10))); $SendPM = substr($return, (strrpos($return, "SendPM") + 15), ((strrpos($return, "SendPM") - 2) - (strrpos($return, "SendPM") + 15))); $SendPM = substr($return, (strrpos($return, "SendPM") + 6), ((strrpos($return, "version") - 2) - (strrpos($return, "SendPM") + 6))); Please send PM to let you know exact details, whole specification.
