Q:

How do you load data from XML file to a ORACLE table?

Answer

You need to first create a table in oracle that matches with the fields of the XML data.


So to get the XMl into the table, you can create a generic procedure that moves an XML document into a table by converting the elements to Oracle Canonical format.


Oracle Canonical format is as follows:


<ROWSET>


   <ROW>  


     <column_name_1 />


     .


     .


     </ROW>


     <ROW>


         <column_name_1 />


         .


         .


      </ROW> 


        .


        .


</ROWSET>        


ROW is used for the table names


ROWSET is used for the XML document


You can get the XML into the canonical form using XSL:


<?xml version="1.0"?>


<xsl:stylesheet 


             xmlns:xsl="https://www.w3.org/1999/XSL/Transform"                   


             version="1.0">


     <xsl:template match="/">


          <ROWSET>


               <ROW>


                         <Attribute_name>                      


                             <xsl:value-of select="Table_name/Attribute_name" />


                         </Attribute_name>


                < /ROW>


          </ROWSET>


     </xsl:template>


</xsl:stylesheet>


To transform the XML document into the canonical form, you can write a procedure. Make sure you include the line below in your procedure code:


v_rows := DBMS_XMLStore.insertXML(


                v_context,    


                XMLType.transform(p_xml_in, p_xsl_in));


The only remaining step is calling your procedure: 


DECLARE


   v_xml XMLType := XMLType( YOUR XML Document );


   v_xsl XMLType := XMLType( YOUR XSL Document );


BEGIN 


   procedure_name(v_xml, v_xsl, 'table_name');


END;
