->pointer will actually give you the tree starting from where you have traversed to in the xml_smart object. It will be a hash which you can use like an ordinary hash.

You can traverse the object using the method described above and it will move the pointer. 


         ___________node1
        |  
root ---|-----------node2
        |___________node3
                     ^
                     |________________Pointer could be here.

Now when you ask for ->content() it will give you the content at node3 and if you ask for ->pointer it will give you the sub-tree starting from node3 in a hash.

Hope that helps - Let me know if you need further clarification.
