Yup, I found this out too... (I guess by prolog you mean something like:-

<?xml version="1.0"?>
<!DOCTYPE BlastOutput PUBLIC "-//NCBI//NCBI BlastOutput/EN" "NCBI_BlastOutput.dtd">

Sadly this occurs for every XML document in the file, and makes the parser
unhappy even when I wrap the whole file in a top level tag.

In the end I stripped out all the lines like the above from the file
(from 1000's of individual  XML documents), then I did somthing like

cat "<Start>" multi_xml_document_files_(with_prologs_removed) "</Start>" | my_xml_parser.plx

Except that exact syntax won't work, but you get the idea.

How could I request some XML::Parser options to make its checking less
strict? Is this a bad road to go down?

Thanks very much,
Dan.
