fn!extract does not like letter p??

Hi All,

For any reason I can't imagine, if you run this instruction in a rule;

fn!extract("<a>some text</a>","<a>","</a>")

you will get {"some text"} as a result, which is what I expected.

But if you run this one

fn!extract("<p>some text</p>","<p>","</p>")

you get nothing as result.

Another example of this strange behaviour:

fn!extract("<l>some text</l>","<",">") returns {"l","/l"}, which is fine

fn!extract("<p>some text</p>","<",">") returns nothing, which is inexplicably to me

Any idea on why is that happenning?. I've tested that on Appian v25.1

Regards!
