Cursor inside DBMS_XMLGen.newContext SetRowTag?

Question

Hi,
I have the following code
v_ctx := DBMS_XMLGen.newContext('select ' || chr(39) || 'F5' || chr(39) || ' as "sender",
                                        payloadid as "messageId",
                                        ordernumber as "orderNumber",
                                        recordtype as "recordType",
                                        billtoid as "billToId",
                                        shiptoid as "shipToId",
                                        shipperid as "shipperId",
                                        shipfromid as "shipFromId",
                                        currency as "currency",
                                        siteid as "siteId",
                                        carrierid as "carrierId",
                                        forwarderid as "forwarderId",
                                        flexcharacterattr7 as "flexCharacterAttr7",
                         hazardousindicator as "hazardousIndicator",
                                        motcode as "motCode",
                                        enduserid as "endUserId",
                                        orderdate as "orderDate",
                                        paymentterm as "paymentTerm",
                                        routedexportindicator as "routedExportIndicator",
                                        cursor(select linenumber as "lineNumber"
                                                 from f5_ec_order_ln_out b
                                                where b.ordernumber = a.ordernumber) "lineRequest" 
                                   from f5_ec_order_hdr_out a
                                  where payloadid = 15');
DBMS_XMLGen.setRowsetTag(v_ctx, 'orderRequest');
DBMS_XMLGen.setRowTag(v_ctx, 'headerRequest');This is returning rows with a Row tag
<lineRequest>
<lineRequest_ROW>
<lineNumber>1078</lineNumber>
</lineRequest_ROW>
<lineRequest_ROW>
<lineNumber>1079</lineNumber>Is there any sort of command like
DBMS_XMLGen.setRowTag(v_ctx, 'headerRequest');
for a cursor inside this statement are there any like routines like
DBMS_XMLGen.setRowsetTag(v_ctx, 'orderRequest');
DBMS_XMLGen.setRowTag(v_ctx, 'headerRequest');
for the cursor part inside or do I need to simply use a replace on my XML after?
Thanks in advance!

You can use xmlagg instead of the inner cursor:
SQL> declare
  2   v_ctx dbms_xmlgen.ctxHandle;
  3   x varchar2(2000);
  4  begin
  5    v_ctx := DBMS_XMLGen.newContext('select dname ,
  6                                            (select xmlagg(xmlelement("lineNumber",ename))
  7                                                   from emp b
  8                                                  where b.deptno = a.deptno) "lineRequest"
  9                                     from dept a');
10  
11    DBMS_XMLGen.setRowsetTag(v_ctx, 'orderRequest');
12    DBMS_XMLGen.setRowTag(v_ctx, 'headerRequest');
13    x := dbms_xmlgen.getxml(v_ctx);
14    dbms_output.put_line(x);
15  end;
