Get Error Message when displayed?

How would I get the value of "You must accept the Bank of the West terms before registering." from the below, when displayed to user?  The only thing I see that is different is the div 2 before the value I want, has a class of "c-alert__icon--big c-alert__icon--error".

<div class="c-alert__container js-notifications">
