Hi ,

 I have created a Xml string type and passed it to a Apex call out method. The result of this method is a string too. Now i would want to convert the Result Xml string into a List object. please suggest.

public class APImageUpdates {
  public void APFilesMissing()
    {
      // Create list for Available Aupairs
      List<Contact> APContacts = [Select Id,AP_Status__c,RecordTypeId from Contact where AP_Status__c ='Available' AND contact.RecordTypeId ='012300000000AHhAAM' ];
      
      // Root of the Xml list
      string XmlString = '<APFilesData>';      
      for(Contact contact: APContacts) 
      {            
        for(AP_Application__c APAppObj: [Select Id,Au_Pair__c,AP_Folder_Name__c,Photo1__c,Photo2__c,Photo3__c,Photo4__c From AP_Application__c where Au_Pair__c =: contact.Id])
        {        
          if(APAppObj.IsExist_Photo1__c == false) 
          {  
            XmlString += '<APFiles>';
            XmlString += '<Apfoldername>';
            XmlString += APAppObj.AP_Folder_Name__c;
            XmlString += '</Apfoldername>';
            XmlString += '<Id>';
            XmlString += APAppObj.Id;
            XmlString += '</Id>';
            XmlString += '<APID>';
            XmlString += APAppObj.Au_Pair__c;
            XmlString += '</APID>';
            XmlString += '<FileUrl>';
            XmlString += APAppObj.Photo1__c;
            XmlString += '</FileUrl>';
            XmlString += '</APFiles>';    
                                     
          }
          
          if(APAppObj.IsExist_Photo2__c == false )
          {
            XmlString += '<APFiles>';
            XmlString += '<Apfoldername>';
            XmlString += APAppObj.AP_Folder_Name__c;
            XmlString += '</Apfoldername>';
            XmlString += '<Id>';
            XmlString += APAppObj.Id;
            XmlString += '</Id>';
            XmlString += '<APID>';
            XmlString += APAppObj.Au_Pair__c;
            XmlString += '</APID>';
            XmlString += '<FileUrl>';
            XmlString += APAppObj.Photo2__c;
            XmlString += '</FileUrl>';
            XmlString += '</APFiles>';  
          }
          
          if(APAppObj.IsExist_Photo3__c == false )
          {
            XmlString += '<APFiles>';
            XmlString += '<Apfoldername>';
            XmlString += APAppObj.AP_Folder_Name__c;
            XmlString += '</Apfoldername>';
            XmlString += '<Id>';
            XmlString += APAppObj.Id;
            XmlString += '</Id>';
            XmlString += '<APID>';
            XmlString += APAppObj.Au_Pair__c;
            XmlString += '</APID>';
            XmlString += '<FileUrl>';
            XmlString += APAppObj.Photo3__c;
            XmlString += '</FileUrl>';
            XmlString += '</APFiles>';  
          }
          
          if(APAppObj.IsExist_Photo4__c == false )
          {
            XmlString += '<APFiles>';
            XmlString += '<Apfoldername>';
            XmlString += APAppObj.AP_Folder_Name__c;
            XmlString += '</Apfoldername>';
            XmlString += '<Id>';
            XmlString += APAppObj.Id;
            XmlString += '</Id>';
            XmlString += '<APID>';

            XmlString += '</APID>';
            XmlString += '<FileUrl>';
            XmlString += APAppObj.Photo4__c;
            XmlString += '</FileUrl>';
            XmlString += '</APFiles>';  
          }
          
        }
      }
      
      //Close root Xml
      XmlString += '</APFilesData>';
      ServiceMethod(XmlString);
      }
   
   //Service Method  
   public static void ServiceMethod(string xml)
   {
     string ServiceResult = '';
     WebServiceOrg.AjaxSoap Service = new WebServiceOrg.AjaxSoap();
      ServiceResult = Service.GAPNetworkImages(xml);  
      Checkboxupdate(ServiceResult);   
   }
 
   public static void Checkboxupdate(string xml) 
   {

 List<AP_Application__c> APAppObj = new List<AP_Application__c>();
   }

I need to convert the resulting Xml and populate the results to List<AP_Application__c>. can someone please suggest

Thank you.
