how to match a form like <form class='jbu-form' data-reacted='.0.0' novalidate="">

rms

I have this form:

<form class='jbu-form' data-reacted='.0.0' novalidate="">

I can not find it using form id, form name or form url.

Is there a chance to find this form?

forum url << would tbe the same as the one the form is located on
form id << is empty form name << would be the button caption you are about to press like *Submit*
form class=jbu-form
