How to delete multiple empty lines in item assignment block in WebUI

Question

Hi Experts,
   When i am reading 'BTAdminI' context node data, I am getting empty lines along with data. I can able to delete only one empty lines when its executing second empty line its failing in loop. Can you suggest me how can i delete multiple empty lines. I am using below code.
DATA: lr_entity1           TYPE REF TO cl_crm_bol_entity,
        lr_current          TYPE REF TO if_bol_bo_property_access,
        lr_iterator         TYPE REF TO if_bol_bo_col_iterator,
        lv_strukname        TYPE strukname,
        dref                TYPE REF TO data,
        lv_thtmlb_tableview TYPE REF TO cl_thtmlb_table_view,
        lr_cn               TYPE REF TO cl_bsp_wd_context_node_tv,
        cr_mixed_node_tv    TYPE REF TO cl_bsp_wd_mixed_node.
    FIELD-SYMBOLS: <fs_line_structure> TYPE data.
    lr_iterator = me->typed_context->btadmini->collection_wrapper->get_iterator( ).
    TRY.
        lr_current = lr_iterator->get_first( ).
      CATCH cx_root.
    ENDTRY.
    WHILE lr_current IS BOUND.
      lr_entity1 ?= lr_current.
      CHECK lr_entity1 IS BOUND.
      lr_entity1->get_attr_struct_name( RECEIVING rv_result = lv_strukname ).
      IF lv_strukname IS NOT INITIAL.
        CREATE DATA dref TYPE (lv_strukname).
        ASSIGN dref->* TO <fs_line_structure>.
        IF <fs_line_structure> IS ASSIGNED.
          lr_current->get_properties( IMPORTING es_attributes = <fs_line_structure> ).
          IF <fs_line_structure> IS INITIAL.
            me->typed_context->btadmini->collection_wrapper->remove( lr_current ).
            EXIT.
          ENDIF.
        ENDIF.
      ENDIF.
      TRY.
          lr_current = lr_iterator->get_next( ).
        CATCH cx_root.
      ENDTRY.
    ENDWHILE.

Hi Nitish,
Try below code instead of your code,
Data:
lt_empty_lines  TYPE TABLE OF REF TO cl_crm_bol_entity,
lr_entity TYPE REF TO cl_crm_bol_entity.
After getting collection from BTadmini use the below code.
lr_iterator ?= lr_coll->get_iterator( ).
    lr_entity ?= lr_iterator->get_first( ).
    WHILE lr_entity IS BOUND.
      IF lr_entity->is_send_active( ) EQ abap_false.
        APPEND lr_entity TO lt_empty_lines.
      ENDIF.
      lr_entity ?= lr_iterator->get_next( ).
    ENDWHILE.
    LOOP AT lt_empty_lines INTO lr_entity.
      typed_context->btadmini->collection_wrapper->remove( lr_entity ).
      lr_entity->delete( ).
    ENDLOOP.
