on commit preserve rows as
with myXML as (
select test_id||'-'||ship_seq_nbr as scnro_id, TRKNG_NBR,  
xmltype(BASELINE)
xmlcol from IAT.ship_info
where isvalid(baseline) = 1)
select scnro_id, TRKNG_NBR, TRKNG_NBR,
extractvalue(xmlcol,'//MNBR') "MN",
extractvalue(xmlcol,'//P1') "P1",
extractvalue(xmlcol,'//RECPCNTRYCD') "Dest",
extractvalue(xmlcol,'//RECPNM') "Recipient_Name",
extractvalue(xmlcol,'//SNDRCNTRYCD') "Origin",
extractvalue(xmlcol,'//SHIPPING_DEVICE') "Software",
extractvalue(xmlcol,'//SVCTYPCD') "Service"
