Can you please help me out?

Answer 1

I can offer this function to easily extract the value in classic ASP:

function findStringBetween(s_string, s_pre, s_post, n_options)
  ' n_options:
  '  1: IGNORE case in the search
  dim a, b
  ' init
  findStringBetween = ""
  ' find pre-word
  a = instr(1, s_string, s_pre, n_options)
  if a>0 then
    a = a + len(s_pre)
    b = instr(a, s_string, s_post, n_options)
    if b>0 and not (s_post = "") then
      findStringBetween = mid(s_string, a, b-a)
    else
      findStringBetween = mid(s_string, a)
    end if
  end if
end function

Include this in your code, then you can use it like this:

dim my_value
my_value = findStringBetween(s_soap_response, "<getOrderFileResult>", "</getOrderFileResult>", 0)
