the behavior in php 5.3.2 is the expected
string(3) "png"
:-)
will you offer a bugfix for php version 5.2.x?

***problematic code:
echo var_dump(filter_var($xml["ext"], FILTER_SANITIZE_STRING));
***expected result (by version 5.2.1):
string(3) "png"
***result by version 5.2.12 and 5.2.13
bool(false)

I don't see a difference betweeen the expected and actual results. Also
if there is a problem with filter_var and __toString, please provide a
simple script to reproduce it (small class + filter_var only).
Also try using 5.3.2 as I have fixed something related to toString
there.

Description:
------------
In 5.2.1 we always received the string 'png' in example 2. It seems that
filter_var does not call the "__toString" (or something similar) Method
at least for SimpleXMLElement objects.
Example 3 is working correctly.
Test script:
---------------
class Benutzer
{
protected $name;
public function __construct( $name )
{
$this->name = $name;
}
public function __toString()
{
return $this->name;
}
}
$benutzer = new Benutzer( 'TEST' );
$xmlstring = '<?xml version="1.0"
encoding="iso-8859-1"?'.'><file
uuid="samplefile_1234234646sdfsdf"
name="openengine_logo" ext="png" status="released"
action="update">
<meta>
<attribute key="title" value="Download A"/>
<attribute key="product_name" value="Product A"/>
<attribute key="product_name" value="Product B"/>
<attribute key="product_name" value="Product C"/>
<attribute key="product_family" value="Product Family A"/>
<attribute key="product_version" value="1.0"/>
<attribute key="group_main" value="Group A"/>
<attribute key="group_sub" value="Group B"/>
<attribute key="document_type" value="Image"/>
<attribute key="document_type" value="Video"/>
<attribute key="document_type" value="Audio"/>
<attribute key="language" value="en"/>
<attribute key="language" value="de"/>
<attribute key="description" value="This is a sample file"/>
<attribute key="release_date" value="2003-06-04T12:30:17"/>
</meta>
<auth folder="YYY"/>
<user id="XXX"/>
</file>';
$xml = simplexml_load_string($xmlstring);
