i am new to XML and i was attempting to use the xmlElement function in SQL to produced this output:

<?xml version="1.0" encoding="utf-8"?>
<Projects>
  <Project action="modify">
    <ProgramCode>M0E1</ProgramCode>
    <RecipientId>36</RecipientId>
    <FederalProjectNumber>0229473</FederalProjectNumber>
    <Details>
      <Detail action="modify">
        <LineNumber>30</LineNumber>
	<ProgramCode>M0E1</ProgramCode>
	<ImprovementType>47</ImprovementType>
	<ACFunds>15685747</ACFunds>
	<FederalFunds>0</FederalFunds>
	<ACConvAmount>791,288.00</ACConvAmount>
      </Detail>
    </Details>
  </Project>
  <Project action="modify">
    <ProgramCode>M0E1</ProgramCode>
    <RecipientId>36</RecipientId>
    <FederalProjectNumber>0229473</FederalProjectNumber>
    <Details>
      <Detail action="modify">
        <LineNumber>31</LineNumber>
	<ProgramCode>M0E1</ProgramCode>
	<ImprovementType>17</ImprovementType>
	<ACFunds>1,340,213.00</ACFunds>
	<FederalFunds>0</FederalFunds>
	<ACConvAmount>791,288.00</ACConvAmount>
      </Detail>
    </Details>
  </Project>
</Projects>


so far this was what i have:
select xmlElement("Projects",
                  xmlElement("Projects",
                             xmlAttributes(aci.proj_action as "action"),           
                             xmlElement("ProgramCode",aci.prog_code),
                             xmlElement("RecipientID",aci.recipient_id), 
                             xmlElement("FederalProjectNumber",aci.proj_num),
                             xmlElement("LineNumber",aci.detail_line_num),
                             xmlElement("ImprovementType",aci.improvement_type),
                             xmlElement("ACFunds",aci.federal_fund),
                             xmlElement("ACConvAmount",aci.bill_suspen))) as result
  from (select fai.proj_num,   
               'modify' proj_action,
               recipient_id,
               fai.prog_code, 
               fai.detail_line_num, 
               fai.improvement_type,
               fai.federal_fund,
               fai.advance_const,
               fai.bill_suspen,
               row_number() over (partition by fai.proj_num 
                                  order by fai.proj_num, fai.advance_const desc) rn
          from fmis_ac_intfc fai) aci;

output:
<Projects><Projects action="modify"><ProgramCode>M0E1</ProgramCode><RecipientID>36</RecipientID><FederalProjectNumber>0229473</FederalProjectNumber><LineNumber>31</LineNumber><ImprovementType>17</ImprovementType><ACFunds>0</ACFunds><ACConvAmount>791288</ACConvAmount></Projects></Projects>

these are the create table and sample data:
create table fmis_ac_intfc
(proj_num         varchar2(40),

 detail_line_num  number,
 improvement_type varchar2(40),
 federal_fund     number,
 advance_const    number,
 bill_suspen      number)
 

Insert into FMIS_AC_INTFC (PROJ_NUM,PROJ_ACTION,PROG_CODE,RECIPIENT_ID,DETAIL_LINE_NUM,IMPROVEMENT_TYPE,FEDERAL_FUND,ADVANCE_CONST,BILL_SUSPEN) 
values ('0229473','modify','M0E1',36,31,'17',0,1340213,791288);
Insert into FMIS_AC_INTFC (PROJ_NUM,PROJ_ACTION,PROG_CODE,RECIPIENT_ID,DETAIL_LINE_NUM,IMPROVEMENT_TYPE,FEDERAL_FUND,ADVANCE_CONST,BILL_SUSPEN)

Dear,

You can fetch data from xml using extractvalue function in your select query and can insert data into your table.Please read below mentioned document.

You missed the point, it is the opposite the input is in basic data types (numbers, strings) and the output is XML.

You can simply use concatenate operator:
SQL> select '<?xml version="1.0" encoding="utf-8"?>
  2  ' || xmlserialize (document
  3           xmlelement(
  4             "Projects",

  6               xmlelement(
  7                 "Project",
  8                 xmlattributes(proj_action "action"),
  9                 xmlforest(
 10                   prog_code    "ProgramCode",
 11                   recipient_id "RecipientId",
 12                   proj_num     "FederalProjectNumber",
 13                   details "Details"))
 14               order by prog_code, proj_action))
 15           indent size = 2) res
 16  from ( select proj_action, prog_code, recipient_id, proj_num,

Xmlserialize apply a format to an XMLTYPE and returns a CLOB on which you can apply concatenate operator.
XMLTYPE contains a method named GetClobVal which also returns a CLOB from an XMLTYPE.
SQL*Plus automatically applies this method when you select an XMLTYPE.
