All,

I have an XML document with an external parameter entity in the doctype. When I use toString on the XML::LibXML document object, this entity is being expanded in the doctype. Is there any way to turn expansion off on such entities? I am alreadying turning off the expand_entities option, and it works throughout the rest of the document, but this seems not to impact the the doctype tag.

Here is some sample XML, demonstrating what I am talking about:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE student [
  <!ENTITY % student SYSTEM "http://www.university.com/student.dtd">
  %student;
]>

Using the provided example, "%student;" is being replaced by the contents of the entity when I print out the document. I would like to be able to print the doctype tag in the same format that it was provided (i.e. unexpanded).

Here are the parameters that I am passing to the LibXML parser:

  $parser->line_numbers(1);
  $parser->validation(0);
  $parser->load_ext_dtd(1);
  $parser->expand_entities(0);

Please let me know if there is any other information that I could provide that would prove useful, and thanks for your consideration.
