var sidebar_align = 'right';
var content_container_margin = parseInt('350px');
var sidebar_width = parseInt('330px');
Is raq4 or raq550 supporting file.xml ?
If it's a very stupied question, please forgive me
XML has nothing to do with the server hardware.
Both PHP and Perl have XML support modules which you can either add (in the case of Perl) or activate (in the case of PHP)
Java and JSP support the standard, so if you install Tomcat you can use it also.
I hope that helps
