Dynamic Labels using if statement

[Seth Parkhurst]

I am sure this is posted somewhere but I am not able to find it.  But when using the new dynamic labels how do we implement an if/then/else statement.

something like this 

label

My Label needs value = {$value}

value Xpath expression if($control1 = 1) then $value0 else if($control2 =1) then $value1 else ''

Hi Seth,

In Control Settings, Label, for the template parameter, instead of choosing Control Value, choose XPath Expression, and then use an expression like:

    if(//control-1 = '1') then 'a'

    else if(//control-2 = '1') then 'b'

    else ''

Note that in those XPath expressions, for now (see #‌309), you need to use `//control` instead of `$control`. You'll let me know if this works for you!

It works thank you!  I figured it was documented but I had searched and did not find it.

Excellent Seth; and yes, it is a bit tricky, especially the part about having to access control values with `//control` instead of `$control`, this until #‌309 is taken care of. And thank you for the confirmation.
