[TYPO3] Dynamic flash menu using XML

[Tan Le]

Hi all,

I have a flash menu that reads its content and links from an XML file
like below:

<?xml version="1.0" encoding="iso-8859-9"?>
<root>
	<menu txt="About Us" link="index.php?id=5">
		<submenu txt="Careers" link="index.php?id=39"/>		
		<submenu txt="Contact Us" link="index.php?id=38"/>
		<submenu txt="Board &amp; Management Team"
link="index.php?id=37"/>
	</menu>
	<menu txt="Product &amp; Network">
		<submenu txt="VPN" link="index.php?id=35"/>
		<submenu txt="Internet" link="index.php?id=34"/>
		<submenu txt="Voice" link="index.php?id=33"/>
		<submenu txt="Network" link="index.php?id=32"/>
	</menu>
	<menu txt="Business">
		<submenu txt="News" link="index.php?id=29"/>
		<submenu txt="Investors Relation"
link="index.php?id=28"/>
	</menu>
	<menu txt="Partners">
		<submenu txt="Partners Program" link="index.php?id=26"/>
		<submenu txt="Become a Partner" link="index.php?id=25"/>
		<submenu txt="Partner Login" link="index.php?id=24"/>
	</menu>
</root>


I have 2 questions:

1. I am wondering if typo3 can generate its menu dynamically to an xml
file store in fileadmin/templates folders? Or is there any extension
that makes flash menu to be dynamic?  

2. why is it that I cannot edit the file menu.xml in the file fileadmin
folder? But I can edit all other .html file, is this a security reason ?

Any help is greatly appreciated

Regards,

Tan
