My data looks like this:

<todo>
filename: call john doe_20120405_081431_
call john doe_20120405_081431_about car
call john doe_20120405_081431_about car_about offer
Update-YN:y
OpenClosed_OC:O
Status-RYG:G
<todo>
filename: till garden_20120405_081432_
till garden_20120405_081432_get gas
till garden_20120405_081432_get oil
Update-YN:N
OpenClosed_OC:O
Status-RYG:G
<todo>

The objective is to pull out the first <todo> and if "Update-YN:Y" then process just that todo. I am thinking I need to make an array from the original array splitting the elements upon <todo>. I will have many more than two elements however this is representitive data. This is a project for my learning.

My code thus far is:

@pimworking = File.open('pim_working.txt')
puts @pimworking.readlines

thx

I think you are looking for something like this

pimworking = File.open('pim_working.txt').readlines

todos = Array.new()
row = Array.new()

pimworking.each do |ln|
  # there is no fallback for last of todos (so assuming series ends with <todo>)
  if ln.match(/<todo>/) then
    temp = Array.new(row)  # make a shadow copy instead of reference
    todos << temp
    row.clear
  else
    row << ln
  end
end

puts todos.select{|ar| ar.any?{ |w| w.index("Update-YN:y")} }[0]
