Parameter Entity Bug???

["Mark E. Palandri" <mp...@lspeed.com>]

I'm new to the list, so if this problem has been fixed, then sorry to waste
your time.

I am using Java Xerces 2.3.0.

I have been using the org.apache.xerces.parsers.XMLDocumentParser class to
parse XML documents for storage into an XML repository. To get a better idea
of how this class calls the event methods, I extended it and just had the
event methods generate logging output. Everything was working fine until I
sent my parameter entity test document through and ran into what I believe
is a bug.

The problem appears in the non-normalized text of an internal parameter
entity declaration (pe2) that contains a parameter entity reference (to
pe1). I expected the non-normalized text to merely contain the reference,
but it has both the reference and the referenced entity's text, one after
another. The text value is correct; It only contains the referenced entity's
text and no entity reference.

If this isn't a problem, then how do I go about getting the entity reference
but not the referenced entity's text in the non-normalized text? Is there
some feature that affects this?

I have minimized the test case and it is as follows:

bug.xml
-------------------------------------------------
<!DOCTYPE AAA SYSTEM "bug.dtd">
<AAA/>
-------------------------------------------------

bug.dtd
-------------------------------------------------
<!ELEMENT AAA EMPTY>
<!ENTITY % pe1 "This is the value of pe1">
<!ENTITY % pe2 "This entity, paramEnt2, references paramEnt1:
[%paramEnt1;]">
