Fb:switch

Description

Evaluates every fb: tag inside and returns the first one that evaluates to anything other than an empty string. You

can use fb:default to specify a default that gets rendered if nothing else does before it was executed.

Examples

<fb:switch>

<fb:photo pid="12345" />

<fb:profile-pic uid="54321" />

<fb:default>You can't see either the photo or the profile pic</fb:default>

</fb:switch>

Note: fb:default always returns its content. Thus, if it is the first tag within fb:switch, then no other tags get

tested.
