Heap size on HTTPResponse

I have some code as follows:
System.debug('Response Body size is '+response.getBodyAsBlob().size()); 
XmlStreamReader xsr = new XmlStreamReader(response.getBody()); 
String result = parseXML(xsr, dealerId);

The reaponse body size is returned as 3229916, so when I attempt to create an XMLStreamReader variable, the heap size limit is blown.

Can anyone suggest how I can refactor the code so I don't exceed the 6mb limit?

Can u do one think if its wokrs for you .. 

Can you parse the XmlStreamReader  in async mode like queueable apex etc so that you will 12 mb limit 

Execution Governors and Limits: Total heap size Synchronous Limit: 6 MB  - Asynchronous Limit: 12 MB
and Email services heap size is 36 MB.

Unfortunately, it has to be a synchronous call as the user initiates it and I display the results in a visual force page.
