如何創建和輸出數組結果

Question

我叫property_details_array數組，其中數組的每一行的樣子：

["\n  \n  \n   \n    1 W Maple Dr,\n   Atlanta,\n   GA\n   30315" 

我試圖找出乾淨的數據輸出到一個最好的辦法類似於表格的格式，可以是CSV或HTML。

這些數組中的每個數組都有超過200行，因此自動執行此操作將非常有幫助。我開始通過解析數據，如：

property_details_array.each do |i| 
    prop_info = i.split("\n") 
     street = prop_info[4].strip 
     city = prop_info[5].strip 
     state = prop_info[6].strip 
     zip = prop_info[7].strip 
end 

但是，我有點卡在下一步去哪裏。我一直在考慮將它作爲一個數組或數組散列，但我不確定是否比另一個更好，這取決於我將使用多少數據。這兩種方法似乎都有意義，但是由於我不得不首先清理數據，所以我不確定最佳的解決方法。

我如何最好地爲這些值提供未來輸出？

@tadman - 對不起，我沒有解釋，並非常感謝你的幫助。我的意思是說，在仔細觀察數據之後，我意識到結果並不是可預測的順序。有時價格會在[16]，有時則不是。我試圖找出如何將結果導入哈希數組，然後回到繪圖板。

的原始數據，我與外觀類似的工作：

理想情況下，我試圖分析出以下幾點：（街道，城市，省，郵編，價格，BD，BA，廣場.FT）任何想法的最佳方式來做到這一點。

Answer 1

爲什麼不把字段拆分成哈希，如果他們在一個可預測的順序？

你可以這樣做：

FIELDS = [ nil, nil, nil, nil, :street, :city, :state, :zip ] 

details.map do |d| 
    Hash[ 
    FIELDS.zip(d.split("\n").map(&:strip)).select do |key, value| 
     key 
    end 
    ] 
end 
# => [{:street=>"1 W Maple Dr,", :city=>"Atlanta,", :state=>"GA", :zip=>"30315"}] 

構成各包含可映射任何字段散列的數組。這樣做的好處是，如果輸入格式發生變化，如果字段得到重新排列，輸出可以保持一致。

Answer 2

作爲最簡單的解決方案，這看起來很適合存儲散列數組。

property_details_array 
    .map { |row| row.split("\n") } 
    .map { |prop_info| {street: prop_info[4].strip, 
         city: prop_info[5].strip, 
         state: prop_info[6].strip, 
         zip: prop_info[7].strip} }
