The line

   $doc?=?xmldoc($xml); // (line 26)

(where $xml is a string containing a valid xml 
document) raises a fatal error:

"Fatal error: Call to undefined function:  xmldoc() in
d:\...\class.xmltemplate.php on line 26"

I'm running PHP 4.1.0 as an Apache module with Apache 
1.3.22 on Win98 (but I was experiencing the same problem 
with PHP 4.0.6 and Apache 1.3.14). All the required dlls 
(libxml2.dll, iconv-1.3.dll) have been copied to the system 
directory, and phpinfo() tells me that DOMXML is enabled 
(with libxml 2.4.1).
