how i deserialize saml avowal rampart/c (axis2/c)?

i have saml 1.1 saml 1.0 responses utf-8 char * buffers, i reconstruct rampart/c saml_response_t * objects. doubt this:

what repremand slight formulating saml_response_t string?

ideally i'd formula illustration c does following disposes several parser collection repremand order, given axis2/c rare ideas giveaway memory.

my efforts have met failure, indirect especially memory faults, nonetheless here's i have. keep mind deserialize_buffer() slight does only says -- translates aegis an axiom_node_t *, nonetheless i'm open replacing well.

/* : tender xml saml avowal */
xml_data = tcl_getstringfromobj (objv[2], &xml_length);

/* : parse response xml guess */
stream = gstream_mem_create (xml_data, xml_length);
node = axis2_axiom_deserialize_buffer (env, stream);

/* : build saml response parsed xml */
saml_response = saml_response_create (env);
saml_response_build (saml_response, node, env);
arraylist = saml_response_get_assertions (saml_response, env);

/* : emanate the relapse value vigilant */
obj = tcl_newlistobj (0, null);

/* :- modify saml avowal twine */
for (i = 0;
     i < axutil_array_list_size (arraylist, env);
         i++) {
    saml_assertion = (saml_assertion_t *) axutil_array_list_get (arraylist, env, i);
    (saml_assertion != null) {
        assertion_node = saml_assertion_to_om (saml_assertion, null, env);

        component = tcl_newstringobj (axiom_node_to_string (node, env), -1);
        tcl_listobjappendelement (interp, obj, element);

        axiom_node_free_tree (assertion_node, env);
    }
}
