Answer 1

here is the your XML parse in 11g :
select *
  from xmltable('//Entity' passing xmltype
'<?xml version="1.0"?>
<DiseaseCodes>
<Entity><dcode>0</dcode><ddesc>(I87)Other disorders of veins - postphlebitic syndrome</ddesc><claimid>34543></claimid><reauthflag>0</reauthflag></Entity>
<Entity><dcode>0</dcode><ddesc>(J04)Acute laryngitis and tracheitis</ddesc><claimid>34543></claimid><reauthflag>0</reauthflag></Entity>
<Entity><dcode>0</dcode><ddesc>(J17*)Pneumonia in other diseases - whooping cough</ddesc><claimid>34543></claimid><reauthflag>0</reauthflag></Entity>
</DiseaseCodes>
') columns
  "dcode" varchar2(4000) path '/Entity/dcode',
  "ddesc" varchar2(4000) path '/Entity/ddesc',
  "reauthflag" varchar2(4000) path '/Entity/reauthflag'
dcode                                                                            ddesc                                                                            reauthflag
0                                                                                (I87)Other disorders of veins - postphlebitic syndrome                           0
0                                                                                (J04)Acute laryngitis and tracheitis                                             0
0                                                                                (J17*)Pneumonia in other diseases - whooping cough                               0

Using this parser you can create procedure as
SQL> create or replace procedure myXMLParse(x clob) as
  2  begin
  3    insert into MyXmlTable
  4      select *
  5        from xmltable('//Entity' passing xmltype(x) columns "dcode"
  6                      varchar2(4000) path '/Entity/dcode',
  7                      "ddesc" varchar2(4000) path '/Entity/ddesc',
  8                      "reauthflag" varchar2(4000) path '/Entity/reauthflag');
  9    commit;
10  end;
11 
12  /
