function: equals null or is null

In the below function in flow, how do I get the first part of the if statement to basically say, if the result is blank do this...

 

if(
substring(body('Html_to_text'), 0, indexOf(body('Html_to_text'), '---+---')) = null, 
body('Html_to_text'),
substring(body('Html_to_text'), 0, indexOf(body('Html_to_text'), '---+---'))) 

 

When I add the = null it errors out - "The expression is invalid"

Hi @TesDA 

 

if(equals(substring(body('Html_to_text'), 0, indexOf(body('Html_to_text'), '---+---')),null),body('Html_to_text'),substring(body('Html_to_text'), 0, indexOf(body('Html_to_text'), '---+---')))

Can you try this expression? (please check the brackets. I might have missed something there)

 

Basically you have to wrap the condition for '=' in the equals() function. 

 

Hope this Helps!
