Fail to use DomDocument on linux

Hi,

I'm having a problem to instantiate a 'DomDocument' class
with PHP 5.2.4 running on Fedora 7 / Apache 2.2.6
the "new DomDocument;" statement gives:
"Fatal error: Class 'DomDocument' not found ".

the same script runs fine on windows with Apache 2.2.4, PHP 5.2.3

the issue so comes from the install of PHP and its support of the
DomXxxx classes. but the doc (PHP website) indicates that they
are always present under PHP 5.x and simply use the libxml library.
I do have libxml2.so.2.6.31 present in my system, so ?

thanks for any help regarding the way to use that class under linux.

Sylvain.

oups! 'php-xml' is not installed in default config.
"yum install php-xml" solves the issue.
