Hi:

One way would be to find the desired tag, then read lines until you hit the 
next < 
Of course, this won't work if there are < 's imbedded in the data field.

-- tested

object text

---------------------------------
function LoadFile(sequence name)
---------------------------------
integer fn
object line
fn = open(name,"r")
text = {}
while 1 do
   line = gets(fn)
   if atom(line) then exit
   else text = append(text,line)
   end if
end while
return text
end function

-----------------------------------------
function Extract(object tag, object text)
-----------------------------------------
integer i
object found
found = ""
i = 1
while i <= length(text) do -- iterate thru the buffer
   if match(tag,text[i]) then -- look for the <YEAR> tag
      found = text[i] -- store that line
      i += 1 --- go to next line
      while not match("<",text[i]) do -- look for <
           found &= text[i]   -- if not there, add next line to buffer
           i += 1 -- go to next line
       end while
   else i += 1
   end if
end while
return found
end function

-----------------------------[ MAIN ]-------------------------------
text = LoadFile("test.txt")
puts(1,Extract("<NAME>",text))

-- end
                  
Hope that helps
