DevOps, CI/CD and Automation

I post this more in hope than expectation, as a search of this forum reveals many people who've asked this question, but none of those postings were answered.

Here goes. I am attempting to parse an XML documenty in the form of a CLOB but this line:

   xmlparser.parseClob(parser,lclob_file); 

fails with this error:

ORA-20100: Error occurred while parsing: Expected 'EOF'.

The CLOB is inserted into a table by a Java bean. What does the Java need to add to the file buffer so that the EOF is recognised?

TIA, APC

P.S. The actual XML is parseable, because I cut'n'pasted it into a VARCHAR2(32000) item.
