(How) Can a SP call the Function which has BULK COLLECT return?

Question

I have a function using BULL COLLECT to put (XML data) many line into a table type record. (I had this as a function because it's gong to call many times).
From one SP program, I will need to call it to get converted XML data info, how should i call it? If it's single line return, I could use
my_result := get_tbl_xml(p_xml);
but when it's table type, even I defined it, it still get error. Here is the program:
Declare (at package spec)
TYPE OrderDtl_Tab IS TABLE OF xxx%ROWTYPE INDEX BY BINARY_INTEGER;
in_OrderDtlTab OrderDtl_Tab;
FUNCTION get_tbl_xml (p_xml IN CLOB ) RETURN OrderDtl_Tab IS
BEGIN
SELECT extractvalue(VALUE(x), '/xxxx/xxxx') AS xxxx BULK COLLECT
INTO in_OrderDtlTab
FROM TABLE(xmlsequence(extract(xmltype(p_xml), '/Order/Lines/*'))) x;
RETURN in_OrderDtlTab;
END;
PROCEDURE SAVE_A (p_xml IN CLOB )
BEGIN
--- how to call get_tbl_xml to get result, so I will be able to insert into DB table
in_OrderDtlTab := get_tbl_xml(p_xml);
END;

May be this is better
FUNCTION get_tbl_xml (p_xml IN CLOB ) RETURN OrderDtl_Tab IS
BEGIN
SELECT extractvalue(VALUE(x), '/xxxx/xxxx') AS xxxx BULK COLLECT
INTO in_OrderDtlTab
FROM TABLE(xmlsequence(extract(xmltype(p_xml), '/Order/Lines/*'))) x;
RETURN in_OrderDtlTab;
END;
PROCEDURE SAVE_A (p_xml IN CLOB )
yourrow your_table%rowtype;
BEGIN
--- how to call get_tbl_xml to get result, so I will be able to insert into DB table
in_OrderDtlTab := get_tbl_xml(p_xml);
FORALL myrowtype
IN in_OrderDtlTab .FIRST .. in_OrderDtlTab .LAST
INSERT INTO Your_table
VALUES in_OrderDtlTab(yourrow);
END;
END;
