How we can get the dynamic values that exists in PDF

I explain.

I have a PDF Adobe Dynamic XML Form, I would like to extrat the values that already exits in the form, like select box, because I need their ID and Value, to generate another form in HTML.

I don't have the PDF Adodbe Dynamic XML Form source, so I'm wondering if there is a solution or trick to do it.

PS : I attached the form that I want to extract the dynamic data from ... this form is public, so no issue with privacy.

Thanks
