In NeoLoad you aren't trying to parse out objects in the DOM, rather you just need a regular regex expression that includes the text directly left (and then right) of the text area. I.e. your regular expression regex when created in NeoLoad using the Variable Extractor (see documentation link): will wind up looking something like this:
style="font-size:8pt;width:350px;">(.*?)</textarea>
Will extract :"PT. WINDU EKA" (or whatever might be in the text area at the time the response is given).
