webservices using nusoap

i am using nusoa开发者_Python百科p for webservices to intigrate hotel api into my web application.

I create soapclient and called webservice. request is

POST /API/xyz.asmx HTTP/1.0
User-Agent: NuSOAP/0.6.3
Host: xyz.com
Authorization: xyz
Content-Type: text/xml; charset="ISO-8859-1"
Content-Length: 646
SOAPAction: "xyz"

<?xml version="1.0" encoding="ISO-8859-1"?><SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"  xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"  xmlns:xsd="http://www.w3.org/2001/XMLSchema"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"  xmlns:si="http://soapinterop.org/xsd"><SOAP-ENV:Body>
<username xsi:type="xsd:string">xyz</username>xxx000000</hotel_id></ns1:getwebservice>

and response is

HTTP/1.1 200 OK
Cache-Control: private, max-age=0
Content-Type: text/xml; charset=utf-8
Server: Microsoft-IIS/7.5

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><Get_hotel_infoResponse xmlns="http://tempuri.org/"><getwebservice><hotels xmlns="" /></getwebserviceResult></soap:Body></soap:Envelope>
</SOAP-ENV:Body></SOAP-ENV:Envelope>

I am getting the xml response empty in response i.e ,so how could i get the xml data in response.

I am not getting the xmlns link in response. so how will it come?

Do not use NuSOAP, it's long dead. Use PHP's integrated SoapClient.
