I need to export Person and Group request from FIM 2010 and everything was just fine before Microsoft didn't released FIM 2010 R2.

All the difference is coming from the new type of request in FIM 2010 R2 called msidmCompositeType which is kind a wrapper around series of Person and Group requests all together. Can anyone provide me with some guideline on how can I achieve this?

The piece of code that did the magic before FIM2010 R2 looks like this:

extractRequests_Group.XPathFilter ="/Request[TargetObjectType='Group' and RequestStatus='Completed' and CommittedTime>='"+FIMXPathFilterDate +"']";

extractRequests_Person.XPathFilter = "/Request[TargetObjectType='Person' and RequestStatus='Completed' and CommittedTime>='"+FIMXPathFilterDate+"']";

for groups and persons.

This refers to requests that are being batched together by the Sync Engine FIM MA.

Craig and Paul, respectively offer some good insight into the basics and how to do searching.
