Extracting XML out of HTML form

Hello,

I created a xdp file and converted it into HTML using renderHTMLForm operation in workbench. Now I want to submit this HTML form to a servlet and extract the XML out of it.

I was able to submit it but the output is in some encoded format but not XML. Is there any way in which I can extract xml data from a HTML form at the click of a button?

Sample output which I got -

FSPAGENO_=0&FSPAGECOUNT_=2&FSFOCUS_=&FSCLICKEDBUTTON_=&FSINITIALIZED_= &firstName%5B0%5D=Alex&lastName%5B0%5D=Tim&Button1%5B0%5D=Button&textfield1%5B0%5D=&textfield2%5B0%5D=&FSAPPLICA TIONDATA_=H4sIAAAAAAAAAM1Yx87kSI6%2
