PHP 5 & DomXpath

[Janwillem Borleffs]

Hello,

When I use the followng code:

$dom = new domDocument;
$dom->load($xml);
$xpath = new domXPath($dom);
$results = $xpath->query('/');

I get the following error message on the last line:

Warning: Invalid XPath Context in [...] on line [...]

I have a feeling I can fix this problem by calling:

$xpath->registerNamesp ace();

but am unsure about which arguments to use.

Thanks In Advance for any pointers.


Regards,
JW

I am running PHP Version 5.0.0 on Gentoo Linux with Apache2. I tried
exactly the code you posted with my "cdcatalog. xml" (which is actually on
www.w3schools.com), and did not get any warning or errors. I have my error
reporting set to E_ALL.

When I do this afterwards:
print_r($result s);
it returns:
DOMNodeList Object ( )
meaning everything went alright.

Maybe there is something wrong with the XML?

Nope, the bug is in the zend.ze1_compat ibility_mode directive. When you
enable it in the php.ini file, the problem occurs.
