Would work, you could also use dependset to delete foo.xml if either
foo.txt or *.tml or generator.pl is newer than it and then use
available to see if it still is there.

What you really want is to check for the opposite of uptodate, right?
<condition>
<not>
<and>
<uptodate ...> <!-- foo.xml is newer than foo.txt -->
<uptodate ...> <!-- foo.txt is newer than *.tmpl -->
<uptodate ...> <!-- foo.txt is newer than generator.pl -->
</and>
</not>
</condition>
may be better.
