Description:
------------
The stream-oriented XML parser (formerly Expat) produces different output in PHP 5 than it did in PHP 4. I'm unable to read the 

<?xml version='1.0'?>
<!DOCTYPE chapter SYSTEM "/just/a/test.dtd" [
<!ENTITY plainEntity "FOO entity">
<!ENTITY systemEntity SYSTEM "xmltest2.xml">
]>

section of the XML document with PHP 5.

Reproduce code:
---------------
The code under "Example 3. External Entity Example" at http://www.php.net/manual/en/ref.xml.php

Expected result:
----------------
<?xml version='1.0'?>
<!DOCTYPE chapter SYSTEM "/just/a/test.dtd" [
<!ENTITY plainEntity "FOO entity">
<!ENTITY systemEntity SYSTEM "xmltest2.xml">
]>
<CHAPTER>
 <TITLE>Title &plainEntity;</TITLE>
 <PARA>
  <INFORMALTABLE>
   <TGROUP COLS="3">
    <TBODY>
     <ROW><ENTRY>a1</ENTRY><ENTRY MOREROWS="1">b1</ENTRY><ENTRY>c1</ENTRY></ROW>

It seems that entity refs do not get expanded when there is a default handler registered. Instead the default handler gets called with the name of the entity. Surprisingly this behavior is the same in PHP4 and PHP5 (tested with latest snapshots).

Happens when ext/xml is compiled with libxml instead of expat.

Entity issues have been fixed for a while. The remaining issues here are default handler issues.
See Bug #27908
Marking bogus as half of the issues fixed and the rest in already reported
