红宝石地图嵌套阵列

Question

我有这个字符串，我想分成嵌套数组：

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]}' 

这至今：

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

成功地将其划分为：

[ 
    ["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]"] 
]

我想添加一个额外的地图：

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

它返回：

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

但是我在此之后代替：

[ 
    [['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]']] 
] 

的地图显示在其内部被施加本身到整个第二级阵列代替每个元素的。我在这里做错了什么？

Answer 1

在您将被拆分仅第一个元素，而不是劈裂的每一个元素与地图

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

你也可以清理有点提取正则表达式到一个变量

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

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