Hi,

I want to consume one web service and want to pass XML as input parameter into web method but it's giving me error when trying to pass xml as input parameter.

It only understand my input value when I covert input value by "HtmlEncoding" and change "<" to "& lt;" and ">" to "& gt;".

I don't want to do like this and directly pass xml node as input parameter value in web method.

Please reply me back ASAP, It's very urgent.

string SOAPRequest="",SOAPInput="";

XmlDocument doc = new XmlDocument();
SOAPRequest = "<?xml version='1.0' encoding='utf-8'?>";
SOAPRequest += "<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap='http://schemas.xmlsoap.org/soap/envelope'>";
SOAPRequest += "<soap:Body>";
SOAPRequest += "<GetCustomerInfoXML xmlns='http://qa2.alliancetek.com/phpwebservice'>";
SOAPRequest += "<id><customer><id>1</id></customer></id></GetCustomerInfoXML></soap:Body>";
SOAPRequest += "</soap:Envelope>";

doc.InnerXml = @""+SOAPRequest;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://qa2.alliancetek.com/phpwebservice/index.php");
if (proxy != null) 
{
    req.Proxy = new WebProxy(proxy, true);
}
req.Headers.Add("SOAPAction", "http://qa2.alliancetek.com/phpwebservice/index.php/GetCustomerInfoXML");
req.ContentType = "text/xml;charset=\"utf-8\"";
req.Accept = "text/xml";
req.Method = "POST";
//req.ContentLength = 1000;

Stream stm = req.GetRequestStream();
doc.Save(stm);
stm.Close();

//Stream stm;
WebResponse resp = req.GetResponse();
stm = resp.GetResponseStream();
StreamReader r = new StreamReader(stm);
//Response.Write(r.ReadToEnd());
string sResponse = r.ReadToEnd();
