Unable to parser using TouchXML

I am unable to parse response recieve using Touch XML My response from SOAP

Being "unable to parse response" is a very vague description of your problem. However, at first glance I noticed that this XPath query...

resultNodes = [rssParser nodesForXPath:@"//GetImagesResult" error:nil];

...is most likely not matching any elements and thus returning an empty array.

Why? Your XML has a namespace. Use nodesForXPath:namespaceMappings:error: method instead of nodesForXPath:error:. The former has an extra parameter that lets you provide a namespace mapping dictionary. Then edit your XPath query accordingly. See the example below:

NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:
                      @"http://tempuri.org/",
                      @"tempuri", 
                      nil];

// Set the resultNodes Array to contain an object for every instance of an  node in our RSS feed
resultNodes = [rssParser nodesForXPath:@"//tempuri:GetImagesResult" namespaceMappings:dict error:nil];

Also, the last statement of the method is nonsense:

[[rssParser retain] release];

To balance the alloc-init, it should be:

[rssParser release];
