XML Parsing -reading xml file in oracle pl sql example

Please find the below stand alone script followed by sample XML file that I am using for this script.

Steps to be performed.

  1. create a XML file with name OMX_Cxml.xml (by copying the XML file data provided at the end of this post).
  2. Place the xml file in any server path ( in this example I have placed the file in USER_TEMP directory) directory namd and path can be seen in all_directories table
  3. Execute the below script and understand how am i reading each node and attribute value also How am i handling the loops for repeating nodes .
  4. Modify the script as per your xml file.

Issues occured:

1. when using this DBMS_LOB.LOADFROMFILE(DEST_LOB => L_CLOB, SRC_LOB => L_BFILE, AMOUNT => DBMS_LOB.GETLENGTH(L_BFILE));
   the data in xml file is reading in unknown characterset   

   Resolved: by using DBMS_LOB.LOADCLOBFROMFILE

2. when using this dbms_xmlparser.parseclob(l_parser,l_clob) getting the below error
    sqlerrm :ORA-31020: The operation is not allowed, Reason: For security reasons, ftp and http access over XDB repository is not allowed on server side
    resolved : by using
        dbms_xmlparser.parseclob(l_parser, REGEXP_REPLACE(l_clob,'<!DOCTYPE cXML SYSTEM "http://xml.cxml.org/schemas/cXML/1.2.009/InvoiceDetail.dtd">',''));

3. could not able to read the file when file is in "/idc/dev/app/apps/apps_st/appl/zzcus/12.0.0/XMLDIR" and getting the below error.
        ORA-22288: file or LOB operation FILEOPEN failed
            No such file or directory
    temporarily Resolved : by placing the file in  /idc/dev/csf/tmp.

4. Able to read the node values but not attribute values
    resolved : by using
   for Ex: <Identity>178923231</Identity>  by using: dbms_xslprocessor.valueof(current_item,'From/Credential/Identity/text()',from_identity)
   for Ex: <Credential domain="OracleSN">  by using: dbms_xslprocessor.valueof(current_item,'From/Credential/@domain',from_credential);
