First of all, the assignment to $selected in this if statement looks very suspect:

       if (($Request->item("Tab")->item() eq "Support") and ($selected
+ ="CTS"))

Did you want $selected eq "CTS"?

Secondly, I think you are choosing a difficult approach to generating XML. Even though XML is text, it really represents a data structure. A much easier way to create XML is to first create the data structure and then have a module like XML::Simple generate the XML for you. XML looks deceptively simple to produce and parse, and yet it has a lot of rules that need to be followed. Any simple-minded approach to generating XML is bound to have problems once you try to make it work for more general situations. It's much better to use a module which knows about all the formatting rules and will always produce correct XML.
