Problem with DOMXML PHP4.0.4pl1 under W2k

I have PHP4.0.4pl1 under Win2000.

When I am runing this script (example from this site)

<?php
$theXML = "<?xml version='1.0'?>";
$theXML .= " <website><url>";
$theXML .= " URL";
$theXML .= " </url></website>";

$xmlDoc = xmldoc($theXML);
$root = $xmlDoc->root();

$node = array_shift($root->children());
echo $node->content;
?>

PHP is returning me following error message.

Fatal error: Call to undefined function: xmldoc() in f:\usr\www\xml3.php3 on line 8

What am I doing no correct?
Support of domxml is established.

Help me please.
Thanks to All!

you must be config your webserver to support

./configure' '--with-mysql' '--with-apxs2=/var/www/apache2/bin/apxs' '--enable-xslt' '--with-xslt-sablot=/usr/local/sablot' '--with-dom=/usr/local/libxml' '--with-zlib' '--with-expat-dir=/usr/local/expat' '--with-curl' '--with-zlib' '--with-oci8=/usr/local/oracle' '--enable-bcmath' '--enable-calendar' '--with-gettext' '--enable-inline-optimization' '--with-tsrm-pthreads'

Hi,

Thanks for answer
