Detecting column name and value from a xml

Question

Dear all,
I need to create a procedure to get a xml file. The xml file may contain a table data or procedure parameter value. Off course it will also contain a flag if the data is of a procedure or table nnd then it's table or procedure name, column name(in case of table), and value. The procedure will receive the xml file and it does not know the column name in case of table or parameter name in case of procedure and then its value. i.e i have to parse the xml file without knowing the column name for table or parameter for procedure. Then i may populate data to my need. How can i do that? Please help me.
BR.

Answer 1

You need to cast your data into an xmltype and look for the existence of nodes for tables, proceduresm etc
with xmldata
as
  (select  xmltype('<?xml version="1.0" encoding="UTF-8"?>
<Sample UniqueID="KWID_AP" >
     <Description>Sample Application</Description>
     <Table Name="SampleTable" />
     <Procedure Name="SampleProc" />
</Sample>') xml
from dual)
select * from xmldata
where existsnode(xml,'/Sample/Procedure')=1
