Yikes. The only solution I can think of would be:

<field type="if">
 <item1>
        <field type="mergefield">
                <item1>Name</item1>
        </field>
 </item1>
 <item2>==</item2>
 <item3>xx</item3>
 etc.
</field>

And the field object would have to be able to hold text, numbers, or
other field objects.
