Maybe it's a bug about ADO.Recordset

hi,
   i encountered a difficulty when i tried to open a DomDo***ent object.
And 
i could get different RecordCount when i open the xml.
   pls follow my way to recap the scene.
1. rs.Save Domtmp, adPersistXML (rs is an object of the ADO.Recordset, and

to be sure the rs.recordcount is more than 2 now)
2. To revise Domtmp. 
   for example:
   To revise this xml style 
    <rs:data>
                <z:row ....../>
                <z:row ....../>
                <z:row ....../>
   </rs:data>
   to the style below.
     <rs:data>
                <z:row ......></z:row>
                <z:row ......></z:row>
                <z:row ......></z:row>
   </rs:data>

3.Both the two style are correct. But when we load then style which is 
changed.
  DomTmp.loadxml(.....);
 And i use a ADO RecordSet object to open it.
  rs.open DomTmp
 And now u check the recordcount, it's 1 instead of  3. But i think 3 is 
correct. In my opinion, there is something wrong when ADO.RecordSet
analyzes 
the xml style.
 Could u tell me how to resolve it. Thanks
