[xml] SOAP library using libxml2

[Ferhat Ayaz <ayaz jprogrammer net>]

Hi folks,
look for the client/server SOAP library written in the C programming  
language for C applications using libxml2.


Homepage: http://csoap.sourceforge.net



/********************************************************/
Example client using CSOAP

static const char *url =  
"http://csoap.sourceforge.net/cgi-bin/csoapserver";;
static const char *urn = "urn:examples";
static const char *method = "sayHello";

int main(int argc, char *argv[])
{
SoapEnv *env, *res;

 env = soap_env_new_with_method(urn, method);

 soap_env_add_item(env, "xsd:string",
        "name", "Jonny B. Good");
 res = soap_client_invoke(env, url , "");

 soap_xml_doc_print(res->root->doc);

 soap_env_free(res);
 soap_env_free(env);

return 0;
}
