How to access array fields in sudzc.com SOAP result? - objective-c

Question

Sorry to perhaps ask stupid questions, but I'm still having issues with Objective-C syntax.
So, I've got this SOAP response from my sudzc.com generated code. It should contain a SQL SELECT result with veh_id and version as columns.
What I get as a response object is a NSMutableArray,
NSMutableArray* soapArray = (NSMutableArray*)value;
so I walk through it:
unsigned count = [soapArray count];
while (count--) {
id myobj = [soapArray objectAtIndex:count];
NSLog(#"myobj: %#", myobj);
}
What I get as a printout is something like:
myobj: {
item = {
key = version;
value = 1;
};
for each row of the SQL result. If this is a printout of the array element, why is there only the version column and not also the veh_id column?
How do I access the value for the key on the object myobj of type id? Do I have to cast it first?
That's the XML String returned from the Zend Soap-Server:
<?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.[myurl].com/soap" xmlns:ns2="http://xml.apache.org/xml-soap" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><SOAP-ENV:Body><ns1:getActiveVehiclesResponse><return SOAP-ENC:arrayType="ns2:Map[23]" xsi:type="SOAP-ENC:Array"><item xsi:type="ns2:Map"><item><key xsi:type="xsd:string">veh_id</key><value xsi:type="xsd:string">1</value></item><item><key xsi:type="xsd:string">version</key><value xsi:type="xsd:string">1</value></item></item><item xsi:type="ns2:Map"><item><key xsi:type="xsd:string">veh_id</key><value xsi:type="xsd:string">3</value></item><item><key xsi:type="xsd:string">version</key><value xsi:type="xsd:string">1</value></item></item><item xsi:type="ns2:Map"><item><key xsi:type="xsd:string">veh_id</key><value xsi:type="xsd:string">4</value></item><item><key xsi:type="xsd:string">version</key><value xsi:type="xsd:string">1</value></item></item></return></ns1:getActiveVehiclesResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>

Answer 1

No.. You don't need to cast it, since it shows all the data fetched, I am facing problem that the handler method value (of id type) returns first element only.
check following code:
...
request = [service myServiceCall:self action:#selector(myHandlerMethod:) param:param1];
...
}
-(void) myHandlerMethod:(id)value{
NSString *xmlString = [[NSString alloc] initWithData:request.receivedData encoding:NSUTF8StringEncoding];
// now if the "value" returned is type as some array of some object,then any arrays don't handle serialization of all the elements of the array it holds. The following code prints just outer tag. (e.g. )
NSLog("%#",xmlString);
}

Finally found the solution!
The problem lies within the deserializeAsDictionary function.
Since my Soap xml string is structured to have each database column as item - key - value - key - value etc, it adds each column under the key "item" and thus the deserializeAsDictionary function overwrites in the line
[d setObject:v forKey:[child name]]
the already added objects. In a first shot, I have added a column iterator and now call the columns "item1, item2,.." (further optimization might be necessary):
// Deserializes the element in a dictionary.
+(id)deserializeAsDictionary:(CXMLNode*)element {
NSLog(#"deserializeAsDictionary = %#, children: %d", element.stringValue, [element childCount]);
if([element childCount] == 1) {
CXMLNode* child = [[element children] objectAtIndex:0];
if([child kind] == CXMLTextKind) {
NSLog(#"child %# added", [child stringValue]);
return [[[element children] objectAtIndex:0] stringValue];
}
}
NSMutableDictionary* d = [NSMutableDictionary dictionary];
NSInteger i = 1;
NSString *objKey;
for(CXMLNode* child in [element children]) {
id v = [Soap deserialize:child];
if(v == nil) {
v = [NSNull null];
} else {
if([[child name] isEqualToString:#"(null)"]) {
objKey = [NSString stringWithFormat:#"%#",[child stringValue]];
} else if([[child name] isEqualToString:#"key"] || [[child name] isEqualToString:#"value"]) {
objKey = [NSString stringWithFormat:#"%#",[child name]];
} else {
objKey = [NSString stringWithFormat:#"%#%d",[child name],i++];
}
}
[d setObject:v forKey:objKey];
NSLog(#"child %# added", objKey);
}
return d;
}
The result array now looks like:
},
{
item1 = {
key = "veh_id";
value = 29;
};
item2 = {
key = version;
value = 1;
};
}
