紅寶石地圖嵌套陣列

Question

我有這個字符串，我想分成嵌套數組：

x = '{type:paragaph|class:red|content:[class:intro|body:This is the introduction paragraph.][body:This is the second paragraph.]}' 
x << '{type:image|class:grid|content:[id:1|title:image1][id:2|title:image2][id:3|title:image3]}' 

這至今：

x.scan(/\{(.*?)\}/).map {|m| m[0].split(/\|\s*(?=[^\[\]]*(?:\[|$))/)} 

成功地將其劃分爲：

[ 
    ["type:paragaph", "class:red", "content:[class:intro|body:This is the introduction paragraph.][body:This is the second paragraph.]"], 
    ["type:image", "class:grid", "content:[id:1|title:image1][id:2|title:image2][id:3|title:image3]"] 
]

我想添加一個額外的地圖：

x.scan(/\{(.*?)\}/).map {|m| m[0].split(/\|\s*(?=[^\[\]]*(?:\[|$))/)}.map {|m| m[0].split(/\:\s*(?=[^\[\]]*(?:\[|$))/)} 

它返回：

[["type", "paragaph"], ["type", "image"]] 

但是我在此之後代替：

[ 
    [['type','paragaph'], ['class','red'], ['content',['[class:intro|body:This is the introduction paragraph.][body:This is the second paragraph.]']], 
    [['type','image'], ['class','grid'], ['content','[id:1|title:image1][id:2|title:image2][id:3|title:image3]']] 
] 

的地圖顯示在其內部被施加本身到整個第二級陣列代替每個元素的。我在這裏做錯了什麼？

Answer 1

在您將被拆分僅第一個元素，而不是劈裂的每一個元素與地圖

x.scan(/\{(.*?)\}/).map {|m| m[0].split(/\|\s*(?=[^\[\]]*(?:\[|$))/)}.map {|m| m.map {|n| n.split(/\:\s*(?=[^\[\]]*(?:\[|$))/)}} 

你也可以清理有點提取正則表達式到一個變量

regex = /\|\s*(?=[^\[\]]*(?:\[|$))/ 

x.scan(/\{(.*?)\}/).map {|m| m[0].split(regex)}.map {|m| m.map {|n| n.split(regex)}}
