axiom_util_get_first_child_element_with_localname() returns wrong child_node if a sibling is present and the first node does not match

                 URL: https://issues.apache.org/jira/browse/AXIS2C-1528
             Project: Axis2-C
          Issue Type: Bug
          Components: util
    Affects Versions: 1.6.0
         Environment: Linux
            Reporter: Aleksey Mokhonko


Bug is obvious. I just show what to fix.

File: om_util.c
Routine: axiom_util_get_first_child_element_with_localname_attr()
Line: 830
Present: 

if (om_attr_name && NULL != om_attr_value &&
                                    axutil_strcmp(om_attr_name, attr_name) == 0
                                    && axutil_strcmp(om_attr_value,
                                                     attr_value) == 0)
                                {
                                    *child_node = child; /* <--------------------------------  !!!!!!!!!!!!!!!! */
                                    return om_ele;
                                }

Must be:


if (om_attr_name && NULL != om_attr_value &&
                                    axutil_strcmp(om_attr_name, attr_name) == 0
                                    && axutil_strcmp(om_attr_value,
                                                     attr_value) == 0)
                                {
                                    *child_node = next_sibling; /* <-------------------------------- !!!!!!!!!!!!!!!! */
                                    return om_ele;
                                }
