Skipping empty TVs in Ditto

I’m using Ditto to display a staff list, but not all staff members’ documents have all TVs populated. Instead of just leaving a blank line or even a broken image icon, is there a way to have Ditto check for an empty TV and skip it?

e.g.

If John Doe doesn’t have a fax line, I get this:

Name: John Doe
Email: [email protected]
Fax:
Phone: 555 555 5555

what I want is:

Name: John Doe
Email: [email protected]
Phone: 555 555 5555

Any ideas?

In Ditto tpl you can use PHx (without installing PHx) to check if the TV has content.

Another option is to use a snippet for this. There is an example here: http://modxcms.com/forums/index.php/topic,32687.msg198960/topicseen.html#msg198960

Thanks!
