XMLPARSER.parseClob(v_parser, w2_data_clob); returns ORA-20100: Error

Question

I have a script that calls an output file and reads it into a clob. this portion seems to work fine. I next try to do a XMLPARSER.parseClob(v_parser, w2_data_clob);, but I get the following error:
ORA-20100: Error occurred while parsing: Expected 'EOF'.
I am attaching script and output file data. Any and all help is greatly appreciated:

Answer 1

Well thats the problem - the parser is parsng the clob and is not finding valid XML. It will succeed with
<Version_Number> Version 1.1
</Version_Number>
because, although small its valid XML.
Im surprised that is the seeded XML from the HRMS team. Have you tried something like SQLDeveloper to look at the contents of the CLOB? Just to ensure your plsql is pulling all of the data out?
If everything else checks out, I would get an SR logged with Payroll (HRMS) - this is not a BIP issue per se but invalid XML from the HR dev team.
