problem parsing EQHD
 

Hi.
I'm having problem with parsing EQHD in QueryHits which came from bearshare when performing browse host request.
As Gnutella protocol specification says there should open data length right after BEAR vendor code, while I receive other values in this byte (2,4,6,8,10,12,...,etc - all are even). This value have nothing to do with any sizes in QueryHit message (for the messages with same size of the data between xml and EQHD beginning this value differs) and it doesn't indicate whether xml metadata is there.
Does anybody know what this byte mean and how can i detect the presence of xml metadata in this case?
