[TYPO3-mvc] fluid <f:if > with a regular expression

You can't use preg_match in the if-viewHelper. FLUID is not calling 
"eval" on the conditions, but uses a parser with limited functionality 
to resolve boolean expressions. So you might need to create you own 
viewHelper for that.

Btw. - if you don't use/need a <f:else> condition, you don't need to use 
<f:then> then.
