creative way to enable a caption or not on a image slider using REVO TV's

Ok so I have a slider, NIVO SLIDER.

Now when I load slides I have the option to display HTML captions, like this.



Now the title cooresponds to an ID that contains HTML data, like

<div id="myhtmlcaption"><strong>Hello</strong></div>

The problem I am having is, if i use a TV for title I have to load a # in if its not blank, I want to use the same TV for the div ID and the Title, that way they both match up... but obviously one needs a # and one doesn’t. I can’t just do it like this #[[+mytv]] because if I decide I DONT want a caption for that particular slide, I get a blank caption because the # is always loaded in my title, ie: title="#"

so I want to do this conditianally, like this...

if caption title != nil then add # in front of caption title tv for the slider and use the same tv minus the # for the div ID, else.. leave em both blank and don’t use a caption.

any idea’s how to do this? filtering? or etc..

<img src="myimage.jpg" title="[[*myTv:notempty=`#[[*myTv]]`]]" />

super awesome! that did it exactly. love it. I was writing a custom php snippet that transformed it but this is so much better and built in!
