I hava a file with variables and can select with checkbox. How can I write out the result?

For example the file (xml):

<colors>
    <blue>false</blue>
    <red>true</red>
    <orange>true</orange>
    <green>false</green>
</colors>

This belongs to one item. The items stored in arraylist.

I have four checkboxs: blue, red, orange, green.

If i select some of this, show only those items whom has not the selected color.

For example: - if green and red selected show the items which hasn't got green and red colors. - if orange selected show the items which hasn't got orange color.
