Thank you. However, I only need the digits within the ID attribute of
the DIV. Regex that you suggested fails on the following string

----
lksjdfls <div id ='amazon_345343'> kdjff lsdfs </div> sdjfls <div id
=   "amazon_35343433">sdfsd</div><div id='amazon_8898'>welcome</div>
hello, my age is 86 years old and I was born in 1945. Do you know that
PI is roughly 3.1443534534534534534
