Question

I have this response:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <ns2:SurfaceElementListResponse xmlns:ns2="http://isiows.isiom.fr/schema/DmdCreation" xmlns:ns3="http://isiows.isiom.fr/schema/Error" xmlns:ns4="http://isiows.isiom.fr/schema/DmdDetail">

            <name>R04-</name>
            <type>NIVEAU</type>
         </SurfaceElementListResult>
         <SurfaceElementListResult>
            <idSurfaceElement>9486</idSurfaceElement>
            <name>Zone A</name>

         </SurfaceElementListResult>
      </ns2:SurfaceElementListResponse>
   </soap:Body>
</soap:Envelope>

I am waiting each object to be deserialized to NSDictionary, as it works on all the other WS response except one above.
In comparison with other responses, in SOAP.m:+ (id) deserialize: (CXMLNode*) element method, all the responses for the statement NSString* type = [Soap getNodeValue:element withName:@"type"]; return nil, so it is continues with return [Soap deserializeAsDictionary:element]; and I get the necessary result.
In my case when I reach to NSString* type = [Soap getNodeValue:element withName:@"type"]; the statement returns “NIVEAU” for the first object and “ZONE” for the other object, which does not allow the application go and execute [Soap deserializeAsDictionary:element]; and I get a string object instead of NSDictionary as parse result.

Could you please help me solving this issue?

Answer 1

In

// Deserialize an object as a generic object
+ (id) deserialize: (CXMLNode*) element{

    // Get the type
    NSString* type = [Soap getNodeValue:element withName:@"type"];

looking into the [Soap getNodeValue]… I figured out, that the use of this function is rather too general. It is used as for getting the attributes of the field, as the values of the fields.

// Gets the value of a named node from a parent node.

+ (NSString*) getNodeValue: (CXMLNode*) node withName: (NSString*) name {

    // Set up the variables
    if(node == nil || name == nil) { return nil; }
    CXMLNode* child = nil;

    // If it's an attribute get it
    if([node isKindOfClass: [CXMLElement class]])
    {
        child = [(CXMLElement*)node attributeForName: name];
        if(child != nil) {
            return [child stringValue];
        }
    }

    // Otherwise get the first element
    child = [Soap getNode: node withName: name];
    if(child != nil) {
        return [child stringValue];
    }
    return nil;
}

In this care I created a new method which is getting only the attribute value:

// Gets the value of a node attribute
+ (NSString*) getNodeAttributeValue: (CXMLNode*) node withName: (NSString*) name{
    // Set up the variables
    if(node == nil || name == nil) { return nil; }
    CXMLNode* child = nil;

    // If it's an attribute get it
    if([node isKindOfClass: [CXMLElement class]])
    {
        child = [(CXMLElement*)node attributeForName: name];
        if(child != nil) {
            return [child stringValue];
        }
    }
    return nil;
}

and replaced it in Soap:deserialize:

// Deserialize an object as a generic object
+ (id) deserialize: (CXMLNode*) element{

    // Get the type
    NSString* type = [Soap getNodeAttributeValue:element withName:@"type"];
//  NSString* type = [Soap getNodeValue:element withName:@"type"];
    if(type == nil || type.length == 0) {

And it works perfectly for me, till now. Hope it will help others with the same situation.
