macOS XML Question

[mickwaffle]

hi, im looking for a bit of help with XML and SOAP.
I am currently sending data to a web server using. I am using WSMethodInvocation. to sete the parameters, I use WSMethodInvocationSetParameters. However, I am now wondering, how can I add atrributes to my parameters. A the moment I can only do this sort of thing: <parameter > Some text</parameter>
However, I am looking to be able to do something like this:
<parameter value="sometext" > Some text</parameter>

thanks

Have you tried using WSMethodInvocationSetProperty?

 

[mickwaffle]

im not sure how i would use that... i think thats just used for setting properties of the actual WSMethodInvocation as opposed to the actual parameters.

Maybe you could explain what you are trying to do a little bit more clearly. I don't understand why you would have to touch the actual XML message being sent.

this is my code:

// SOAP call settings
	NSURL *url = [NSURL URLWithString:@"http://localhost/Service.asmx"];
	NSString *method = @"myMethod";
	NSString *namespace = @"http://localhost/namespace";
	
	NSDictionary *params = [NSDictionary dictionaryWithObject:@"TEXT VALUE"forKey:@"myParameter"];
	NSArray *paramOrder = [NSArray arrayWithObject:@"myParameter"];
	
	// SOAP call http headers -- some SOAP server impls require even empty SOAPAction headers
	NSDictionary *reqHeaders = [NSDictionary dictionaryWithObject:@"" forKey:@"SOAPAction"]; 
	
	WSMethodInvocationRef soapReq = createSOAPCall(url, method, namespace, params, paramOrder, reqHeaders, soapHeaders);

The function:

WSMethodInvocationRef createSOAPCall(NSURL *url,
                                     NSString *method,
                                     NSString *namespace,
                                     NSDictionary *params,
                                     NSArray *paramOrder,
                                     NSDictionary *reqHeaders)
{
    WSMethodInvocationRef soapReq = WSMethodInvocationCreate((CFURLRef)url,
                                                              (CFStringRef)method,
                                                              kWSSOAP2001Protocol);
	
    
	
    WSMethodInvocationSetParameters(soapReq, (CFDictionaryRef)params, (CFArrayRef)paramOrder);
	
	
	
    // set method namespace
    WSMethodInvocationSetProperty(soapReq, kWSSOAPMethodNamespaceURI, (CFStringRef)namespace);
	
    // Add HTTP headers (with SOAPAction header) -- some SOAP impls require even empty SOAPAction headers
    WSMethodInvocationSetProperty(soapReq, kWSHTTPExtraHeaders, (CFDictionaryRef)reqHeaders);
	
    // for good measure, make the call follow redirects.
    WSMethodInvocationSetProperty(soapReq,    kWSHTTPFollowsRedirects, kCFBooleanTrue);
	
    // set debug props
	
	
    WSMethodInvocationSetProperty(soapReq, kWSDebugIncomingBody,     kCFBooleanTrue);
    WSMethodInvocationSetProperty(soapReq, kWSDebugIncomingHeaders, kCFBooleanTrue);
    WSMethodInvocationSetProperty(soapReq, kWSDebugOutgoingBody,     kCFBooleanTrue);
    WSMethodInvocationSetProperty(soapReq, kWSDebugOutgoingHeaders, kCFBooleanTrue);
	
    return soapReq;
}

I am trying to use apples Web Services to send soap requests to my server. However, instead of having just <myParameter>TEST VALUE</myParameter> in the method body... i need to have <myParameter value="another_value">TEST VALUE</myParameter>

I mis-typed. I meant to suggest you use: WSMethodInvocationSetParameters

But it looks like you are already using it. The XML-RPC format does not support what you are trying to do. Generally it is in the format:
...
<params>
<param>
<value> <TYPE>value</TYPE> </value>
<param>
...
</params>

If the web-service you are consuming is not in strict compliance with XML-RPC you may need to use a third party tool.

ok, thanks a lot for your help
let's say i was to go ahead, and make my xml soap request myself, just as a regular string, what function would i then use to send it off to my webservice?
thanks again

That's easier in many cases. Just use amy http transport protocol. It's guaranteed to work over http.
