How to find a Process Aproval instance to perform the 'Approve' action

Hi, I'm trying to perform an approval action through APEX code, in an extended controller.  

First I do a Submit for Approval, overwriting the standard one with a visualforce custom button. Here is the code in my extended controller:

 

     public PageReference submitApproval() {
        // Create an approval request for the account
        Approval.ProcessSubmitRequest req1 = new Approval.ProcessSubmitRequest();
        req1.setComments('Submitting request for approval.');
        req1.setObjectId(purchaseRequisitionObj.id);

        // Submit the approval request for the account
        Approval.ProcessResult result = Approval.process(req1);
        return Page.PR_Detail_VF;
     }
After that event, the object left in "Pending" approval state. Then in my detail visualforce page, for specific cases, I have a "Direct Approval" button. That button should perform the instance approval changing its state to "Approved". Here is where I'm stuck, because I can not find the way to get the WorkitemId of the request. I mean the workitemId of the instance I asynchronously approved before. This is the code: 
 
     public PageReference directApproval() {
     	
		// Instantiate the new ProcessWorkitemRequest object and populate it
		Approval.ProcessWorkitemRequest req2 = new Approval.ProcessWorkitemRequest();
		req2.setComments('Direct approval by requester');
		req2.setAction('Approve');
		req2.setNextApproverIds(new Id[] {UserInfo.getUserId()});
		req2.setWorkitemId("FROM WHERE I CAN GET THIS ID??");
		
		// Submit the request for approval
		Approval.ProcessResult result2 =  Approval.process(req2);
		
        return Page.PR_Detail_VF;       
     }
 
Any cue will be highly appreciated. Many thanks in advance Fernando.-
