Description:
------------
When the function xml_parse_into_struct() is used,
XML attribute values that contain escaped characters
in them are not properly un-escaped.

E.g. suppose the tag is:

  <governor name="Jesse &quot;The Body&quot; Ventura"/>

Then the attribute is returned still escaped, as

  Jesse &quot;The Body&quot; Ventura

rather than

  Jesse "The Body" Ventura

like it should be.

This function is supposed to parse
the XML, and &-encodings are part of XML, so it should
properly decode them!

Here's ldd output for my test version of PHP:

Reproduce code:
---------------
<?php
$sample =
  "<?xml version=\"1.0\"?><test attr=\"angle&lt;bracket\"/>";
$parser = xml_parser_create();
$res = xml_parse_into_struct($parser,$sample,$vals,$index);
xml_parser_free($parser);
var_dump($vals); 
?>


Expected result:
----------------
array(1) {
  [0]=>
  array(4) {
    ["tag"]=>
    string(4) "TEST"
    ["type"]=>
    string(8) "complete"
    ["level"]=>
    int(1)
    ["attributes"]=>
    array(1) {
      ["ATTR"]=>
      string(16) "angle<bracket"
    }
  }
}


Actual result:
--------------
array(1) {
  [0]=>
  array(4) {
    ["tag"]=>
    string(4) "TEST"
    ["type"]=>
    string(8) "complete"
    ["level"]=>
    int(1)
    ["attributes"]=>
    array(1) {
      ["ATTR"]=>
      string(16) "angle&lt;bracket"
    }
  }
}
