Hi Ramesh,

See the comments.

You have to do "axiom_node_get_data_element" to get <operation> as the 
element. When you do axiom_node_get_first_element, it will return first 
child whose type is om element.

 First error is caused by axiom_node_free_detached_subtree, which I 
could not find in the code you have sent. Can you send the correct code 
which causes these errors?
