For those who enjoy using ListViews and wish to export the data to a XML file, then this function is for you.  
Thanks to >Mat for the optimised XML format.  
This is an example of the output for a ListView with 2 rows and 2 columns. 
<?xml version="1.0" encoding="UTF-8" ?>
<listview rows="2" cols="2">
    <item>
        <column01>Row 1: Col 1</column01>
        <column02>Row 1: Col 2</column02>
    </item>
    <item>
        <column01
