SimpleXML & internal entity references

["Rolf Brudeseth" <rolfb@xxxxxx>]

I have spent quite a few hours searching with google, but I am still not 
sure how to resolve my problem described below:

I am parsing an XML file with SimpleXML (PHP 5.0.3/FreeBSD STABLE-4/i386). 
It appears that my internal entity references do not get expanded. I see the 
same behaviour with SAX and PHP5.0.3, while it was not a problem with SAX 
and PHP4.1.2.

See below, the 'title' gets added to the array, but not the 'price' and 
'weight'.

I assume that libxml will expand the entity references? I see the value of 
'price' and 'weight' of I look at the data returned by the parser with 
'print_r'.

Anybody got an idea where I have gone wrong?

##########   XML file   ##########
<?xml version='1.0' encoding='iso-8859-1' standalone='yes'?>

<!DOCTYPE prod_desc
[
<!ENTITY dvd '
  <price>14.95</price>
  <weight>6</weight>
'>
]>

<prod_desc version='1.0'>
  <prod item='C107D'>
     &dvd;
     <title><![CDATA[No more Diapers - DVD]]></title>
  </prod>
</prod_desc>

##########   PHP code   ##########
foreach ($xml->children() as $item)
{
  $item_attr = $item->attributes();
  foreach ($item->children() as $element => $cdata)
  {
     // This will not work, bug in PHP
     // $prod_array[$item_attr][$element] = $cdata;
     // Workaround
     $prod_array[eval("return $item_attr;")][eval("return $element;")] = 
$cdata;
  }
}
