INSERTION OF XML DATA INTO THE TABLE USING XMLDOM

Question

hello,
i am using XMLDOM to insert the data into the table
i am using different function of it.
but i am facing the problem to retrive the the multiple entry.
like in my example i have two entry of the ' po number '
& i am using the function
dbms_xmldom.item(l_nodelist, 0)
i which i have to pass index no.
& through this i am getting only single entry according to the index no.
Example on which i am working is
declare
l_xml_data CLOB;
l_xml_doc dbms_xmldom.domdocument;
l_nodelist dbms_xmldom.DOMNodeList;
l_node dbms_xmldom.domnode;
l_xmltype XMLTYPE;
l_po_num VARCHAR2(30);
l_cust_ord VARCHAR2(30);
l_item_code VARCHAR2(30);
begin
l_xml_data := '<?xml version="1.0" encoding="UTF-8"?>

Answer 1

In the following code
l_nodelist := dbms_xmldom.getelementsbytagname(l_xml_doc, 'purchase-order-number');
l_node := dbms_xmldom.item(l_nodelist, 0); -- gets first item from listYou need to understand what the second parm on the .item call does. See [dbms_xmldom.item|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_xmldom.htm#i1126138]
The nodelist is a 0 based array of information and you are only requesting to pull the node info in the first array position. So to get the info in the second array position, you need to use ", 1)". You can also use .getLength and a loop to parse through everything in the node list.
