Problem to insert data into database

Question

hi all ,
I had the two following xmls.
SELECT XMLELEMENT("PUR_ORDER_INFO",
XMLFOREST (PUR_ORDER_ID ,PUR_ORDER_STATTUS ))
FROM T_PUR_ORDER
WHERE PUR_ORDER_ID = 2 ;
and
SELECT XMLELEMENT("PRTCPNT_INFO",
XMLFOREST(PRTCPNT_ID,PRTCPNT_NAME,PRTCPNT_ADDRESS))
FROM T_PRTCPNT
WHERE PRTCPNT_ID = 2 ;
i need to CONCAT these two outputs and put in one xml column(XML_HIST) in another table (t_pur_hist).
SQL> desc t_pur_hist
Name Null? Type
HIST_ID NOT NULL NUMBER
HIST_DT DATE
XML_HIST XMLTYPE
PUR_ORDER_ID NUMBER
i am new to xml.
could anyone please help me.
thanks
rampa.

Be aware that XML needs a root (=starting) tag to be well formed.
<this><is><a><valid><xml_document>!</xml_document></valid></a></is></this>
<here><is><another><valid><xml_document>!</xml_document></valid></another></is></here>
Now we union both XMLs...
<this><is><a><valid><xml_document>!</xml_document></valid></a></is></this>
<here><is><another><valid><xml_document>!</xml_document></valid></another></is></here>
=> not valid!
<documenthistory>
   <this><is><a><valid><xml_document>!</xml_document></valid></a></is></this>
   <here><is><another><valid><xml_document>!</xml_document></valid></another></is></here>
</documenthistory>
Valid!AS for your select problem.
You can add both selects into one.
select xmlelement("Documenthistory",
                  (select xml1 from table1),
                  (select xml2 from table2)
