Regex inside Entity (IBM-WATSON)

Is it possible to put an entity inside of a regex? for example, giving that the entity "@pizza-toppings" contains toppings:

"topping": "<? input.text.extract('(?i)\.+(@pizza-toppings)(?-i)', 1) ?>"

So, if @pizza-toppings matches "onion", then "(?i)\.+(@pizza-toppings)(?-i)" will be "(?i)\.+(onion)(?-i)". If it matches "cheese", then it will be "(?i)\.+(cheese)(?-i)" and so on and so forth.

I've been trying to find a solution but so far I didn't find anything.

Solution

  • Without testing, after I noticed you were including the entity reference into the string. Try to do something like this:

    "topping": "<? input.text.extract('(?i)\.+('+@pizza-toppings+')(?-i)', 1) ?>"
