Creating a custom XML field dependent on field selection - what language?

[PurplePeopleEater]

Hello,

I am writing a custom tool that will have drop down menus for selection of different parts of an XML file, so you can choose what you do and do not want.

What is the best language to achieve this? I was going to use HTML/JavaScript as a pairing.

What are your thoughts?

I envision a window with several drop down menus and then a button to build the XML as per those selections, so i will need something that can handle writing that also.

Thanks,

Maybe take a look at obmenu.
http://obmenu.sourceforge.net/download.html
 It is an editor for the openbox menu. Essentially it provides a graphical way to edit a large xml file.  The program is writen in python.
I've attached an image of the openbox menu. I've also attached an image of what obmenu looks like, and my menu.xml.

Is this what you are looking for?
