Apex call out has an xml response.How can I map the fields in Salesforce to the response I receieved. I could map the fields like clean etc. But how could I map fields like make,model, year relatively.
Assume the fields are : Make__c ,Model__c etc.... Considering the XML response.

XML response is:
<?xml version="1.0" encoding="UTF-8"?> <result> <vin>xxxxxxxxxxx</vin> <id>xxxxxxxxxxx</id> <date>2018-02-08 05:02:15 PST</date> <specs> <VIN /> *<Year>2011</Year> <Make>Chevrolet</Make> <Model>Suburban</Model>* <Trim>LS 1500</Trim></specs><clean>0</clean> <success>1</success> <error /> </result>

Apex callout:

 

public PageReference doVinExtract()
    { 

            HttpRequest httpRequest = new HttpRequest();
            httpRequest.setEndpoint('https:/VinProviderxxxx.php');
            String body = 'id=01123999999198&key=xxxxxxx&vin=1GNSKHE34BRxxxxxxx&mode=test&user=vxxxxxx&pass=slll4250&format=xml';
            httpRequest.setBody(body);
            httpRequest.setMethod('GET');
            Http htt = new hTTP();
            HttpResponse httpRe = htt.send(httpRequest);
            system.debug(httpRe.geTbody());
            String re = httpRe.geTbody();

            Dom.Document doc = httpRe.getBodyDocument();
            Dom.XMLNode address = doc.getRootElement();


        String vinDate= address.getChildElement('date', null).getText();

       String state = address.getChildElement('specs', null).getText();
        // print out specific elements

        System.debug('address: ' + address);
          System.debug('state: ' + state);



            system.debug('result'+re);


             for(Dom.XMLNode child : address.getChildElements()) {
             if(child.getName() == 'specs'){
           System.debug('******'+child.getText());
           }
        }

 I was struck and could not map these three fields:
*<Year>2011</Year> <Make>Chevrolet</Make> <Model>Suburban</Model>
              to the fields in salesforce.
