Answer 1

You mentioned plsql...so here is an example iterating over POs:
begin
for rec in (with q as(select xmltype('<?xml version="1.0"?>
                                       <PO_LIST>
                                        <PO pono="2">
                                         <PNAME>Po_2</PNAME>
                                         <CUSTNAME>Nance</CUSTNAME>
                                         <SHIPADDR>
                                          <STREET>2 Avocet Drive</STREET>
                                          <CITY>Redwood Shores</CITY>
                                          <STATE>CA</STATE>
                                         </SHIPADDR>
                                        </PO>
                                        <PO pono="3">
                                         <PNAME>Po_3</PNAME>
                                         <CUSTNAME>Smith</CUSTNAME>
                                         <SHIPADDR>
                                          <STREET>5 West Drive</STREET>
                                          <CITY>San Francisco</CITY>
                                          <STATE>CA</STATE>
                                         </SHIPADDR>
                                        </PO>
                                       </PO_LIST>') the_xml from dual)  
             select x.street, x.city, x.state
               from q,  --your table here
                    XMLTable(
                     'PO_LIST/PO/SHIPADDR'   --note I have wrapped POs in a PO_LIST tag
                     passing q.the_xml  --your clob here
                     columns
                      street varchar2(1000) path 'STREET',
                      city varchar2(1000) path 'CITY',
                      state varchar2(1000) path 'STATE'
                    ) x)
  loop
   dbms_output.put_line(rec.street||' -- '||rec.city||' -- '||rec.state);
end loop;
