Please give the solution to extract the dynamic data from the given xml string to generate the PDF file ...........

Answer 1

Using either FOP or XEP (RenderX), I get a pdf with the generated text. (Some of the text is off the left margin though.)

Are you sure your PDF is blank? Since you're generating a 50in x 80in page (wow!), maybe you just can't see the text.
