Description:
------------
A lot of php functions that read xml try to validate that the uri
exsist, which is wrong by w3.org.

If the xmlns uri is not valid the functions don't work at all.

Functions tried: 
SimpleXMLElement()
DOMDocument->loadHTMLFile()

I am opening this after opening a problem with w3.org which create the
problematic xml, they realied the fallowing:

http://www.w3.org/2005/10/markup-validator
is a namespace URI, and
there is no
requirement for it to actually point to anything - it's just an
identifier.  If
something makes an assumption that it can retrieve anything at all from
a
namespace URI, it needs to be fixed not to assume that, let alone try
it
automatically.

Reproduce code:

</env:Envelope>


$uri ='c:\a.xml';

$handle = fopen($uri, "r");

$contents = '';
while (!feof($handle)) {
  $contents .= fread($handle, 8192);
}
fclose($handle);

//echo $contents;

$entries = new  SimpleXMLElement($contents);

$result=
$entries->children('http://www.w3.org/2003/05/soap-envelope')->Body->children('http://www.w3.org/2003/05/soap-encoding')->markupvalidationresponse;
echo $result->uri ;

Expected result:
----------------
expected to put on screen
http://www.microsoft.com/en/us/default.aspx

Actual result:
--------------
Nothing is put on screen.

if you change a.xml line
<m:markupvalidationresponse
env:encodingStyle="http://www.w3.org/2003/05/soap-encoding"
xmlns:m="http://www.w3.org/2005/10/soap-encoding">

xmlns:m= uri to anything that validates this works 
example
<m:markupvalidationresponse
env:encodingStyle="http://www.w3.org/2003/05/soap-encoding"
xmlns:m="http://www.w3.org/2003/05/soap-encoding">
