Description:
------------
When I parse an xml file containing <builder>Bill &amp; Joseph Cook</builder> I get Joseph Cook as the value between these tags. It drops anything that comes before &amp;. 

I am using php 5.1.2. I could see this on the section "PHP version" above so I just picked one of the listed.

Reproduce code:
---------------
I am using a class:
class CluistraParser extends XML_Parser{
...
}

to do the parsing based on the parser.php file.

Expected result:
----------------
To get 'Bill & Joseph Cook' as the value for the tag <builder>.

Actual result:
--------------
I get 'Joseph Cook'. Anything before &amp; is dropped and the ampersand does not appear.

I saw an almost similar bug reported by someone for php 5.0.3. The report is http://bugs.php.net/bug.php?id=31139&edit=2.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Reproduce code:
---------------
<?php
require_once 'Parser.php';
class CluistraParser extends XML_Parser{
function cdataHandler($parser, $data)
{
$data=trim($data);
 echo $data."<br/>";
}
}
 $cluistra=new CluistraParser();
 $cluistra->setInputFile("afile.xml");
  $success = $cluistra->parse();
  if (PEAR::isError($success)) {
    die('Parsing failed: '.$success->getMessage());
  }
/*afile.xml has:
    <?xml version='1.0' encoding='ISO-8859-1'?>
    <builder>Bill &amp; John Keen</builder>*/
 ?>

It gives the following as the result:

Bill
&
John Keen

It seems to take the tag <builder>Bill &amp; John Keen</builder> to be containing three cdata sections within it. Therefore the '&' overwrites the 'Bill' and the 'John Keen' overwrites the 'Bill' and finally I have 'John Keen' as the cdata value for this tag; making it seem like it dropped the ampersand and anything before it.

Please "a short but complete example script max. 10-20 lines long" which does not include non-existing files etc.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Thanks for the hint. I will try and find the solution.
