What I’m trying to do is a little more complex then what my questions

  • 0

What I’m trying to do is a little more complex then what my questions asks but I can’t put into words what it is I want to do and my terminology is probably wrong. Sorry. If I can edit the title of my question afterwards to better represent what I want to do I will do so.

I have an array that looks like this:

array = [
  ["bnb ><b>(BASE CABINET)</b>", "bnb ><b>(BASE CABINET)</b>", "1", "22\"", "22\"", "22\""]
  ["bnb >Edgebanding (sides)", "bnb >Edgebanding (sides)", "2", "22\"", "1/2\"", "1/2\""]
  ["bnb >Edgebanding (top/bottom)", "bnb >Edgebanding (top/bottom)", "2", "21\"", "1/2\"", "1/2\""]
  ["bnb >Panel (back)", "bnb >Panel (back)", "1", "21\"", "21\"", "1/2\""]
  ["bnb >Panel (sides)", "bnb >Panel (sides)", "2", "21 1/2\"", "21\"", "1/2\""]
  ["bnb >Panel (top/bottom)", "bnb >Panel (top/bottom)", "1", "22\"", "21 1/2\"", "1/2\""]
  ["bnb >Top (front/back)", "bnb >Top (front/back)", "2", "22\"", "3\"", "1/2\""]
  ["bnb >Top (sides)", "bnb >Top (sides)", "2", "15 1/2\"", "3\"", "1/2\""]
]

What I’m trying to do is get this as a result is basically removing everything after the > in the first element of each subarray and and remove everything before > in the second element of the subarrays:

array = [
  ["bnb", "<b>(BASE CABINET)</b>", "1", "22\"", "22\"", "22\""]
  ["bnb", "Edgebanding (sides)", "2", "22\"", "1/2\"", "1/2\""]
  ["bnb", "Edgebanding (top/bottom)", "2", "21\"", "1/2\"", "1/2\""]
  ["bnb", "Panel (back)", "1", "21\"", "21\"", "1/2\""]
  ["bnb", "Panel (sides)", "2", "21 1/2\"", "21\"", "1/2\""]
  ["bnb", "Panel (top/bottom)", "1", "22\"", "21 1/2\"", "1/2\""]
  ["bnb", "Top (front/back)", "2", "22\"", "3\"", "1/2\""]
  ["bnb", "Top (sides)", "2", "15 1/2\"", "3\"", "1/2\""]
]

and here’s what I’ve got so far as code:

val = 0
@test_list = []
test.each do |comp|
  new_list = test[val]
  new_list.map! { |element| element.gsub(/\s\>.*/, '') }
  comp = comp[0]
  @test_list.push(new_list)
  val = val + 1
end

which removes everything after the > but it does it in both the first and second elements.

    No need to use regular expressions when confronted with a problem 🙂 Sometimes a simple String#split will do.

    source_array = [
  ["bnb ><b>(BASE CABINET)</b>", "bnb ><b>(BASE CABINET)</b>", "1", "22\"", "22\"", "22\""],
  ["bnb >Edgebanding (sides)", "bnb >Edgebanding (sides)", "2", "22\"", "1/2\"", "1/2\""],
  ["bnb >Edgebanding (top/bottom)", "bnb >Edgebanding (top/bottom)", "2", "21\"", "1/2\"", "1/2\""],
  ["bnb >Panel (back)", "bnb >Panel (back)", "1", "21\"", "21\"", "1/2\""],
  ["bnb >Panel (sides)", "bnb >Panel (sides)", "2", "21 1/2\"", "21\"", "1/2\""],
  ["bnb >Panel (top/bottom)", "bnb >Panel (top/bottom)", "1", "22\"", "21 1/2\"", "1/2\""],
  ["bnb >Top (front/back)", "bnb >Top (front/back)", "2", "22\"", "3\"", "1/2\""],
  ["bnb >Top (sides)", "bnb >Top (sides)", "2", "15 1/2\"", "3\"", "1/2\""]
]

target_array = [
  ["bnb", "<b>(BASE CABINET)</b>", "1", "22\"", "22\"", "22\""],
  ["bnb", "Edgebanding (sides)", "2", "22\"", "1/2\"", "1/2\""],
  ["bnb", "Edgebanding (top/bottom)", "2", "21\"", "1/2\"", "1/2\""],
  ["bnb", "Panel (back)", "1", "21\"", "21\"", "1/2\""],
  ["bnb", "Panel (sides)", "2", "21 1/2\"", "21\"", "1/2\""],
  ["bnb", "Panel (top/bottom)", "1", "22\"", "21 1/2\"", "1/2\""],
  ["bnb", "Top (front/back)", "2", "22\"", "3\"", "1/2\""],
  ["bnb", "Top (sides)", "2", "15 1/2\"", "3\"", "1/2\""]
]

arr = source_array.map do |a|
  [
   a[0].split('>').first.strip,
   a[1].split('>', -1)[1..-1].join('>')
  ] + a[2..-1]
end

arr == target_array # => true
