XML Connector problem

[DeeeLite]

Hi

i want to build an application and i have this kind of xml file structure :

<?xml version="1.0" encoding="UTF-8"?>
<trips>
	<trip name="Google dot com">
		<description>Blah blah blah. Blah blah blah blah blah blah. Blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah. Blah blah blah blah blah.</description>
		<cost>1095</cost>
		<tapes>2</tapes>
		<image>images/napa.jpg</image>
		<link>http://www.google.com</link>
	</trip>
             ...
</trips>

Now i have a ComboBox that dynamically list all trip names and when i choose another value in the combobox, it shows the correct description in a text field.

The problem is : i also have a button and when i press the button, i want it to open the link that belongs to the chosen trip name.

Does anyone know how to do this (with the xml connector)?

Thanks in advance!
