Did you try to enable display_errors ?

Here is the code:
<?
$document = new DOMDocument("1.0", "utf-8");
$document->load("http://www.ecb.int/stats/eurofxref/eurofxref-daily.xml");
$xPath = new DOMXPath($document);
$result =
$xPath->query("/gesmes:Envelope/:Cube/:Cube/:Cube[@currency='USD']");
//Oops! $result is somehow empty
if ($result->length > 0) {
print "OK!";
} else {
print "ERROR!";
}
?>

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 possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

Description:
------------
I've tried to execute the
"/gesmes:Envelope/:Cube/:Cube/:Cube[@currency='USD']" XPath
instruction
via the
DOMXPath->query method
on the
"http://www.ecb.int/stats/eurofxref/eurofxref-daily.xml"
but I got neither parse error nor the DOMNodeList. The result is simply
empty.
I validated my istruction here:
"http://www.activsoftware.com/xml/xpath/"
Аnd it get exactly what I want from the XML document.
Reproduce code:
---------------
$from = "USD";
$result =
$xPath->query("/gesmes:Envelope/:Cube/:Cube/:Cube[@currency='" .
strtoupper($from) . "']");
//$result is EMPTY!
