Question

我有一个像这样的字符串：

price<=>656000<br>bathrooms<=>1<br>bedrooms<=>3<br>pets<=>1<br>surface<=>60<br>brokerfree<=>1
model<=>opel/corsa<br>mileage<=>67000<br>vinnumber<=>unknown<br>price<=>145000<br>year<=>2010<br>condition<=>2<br>transmission<=>unknown<br>cartype<=>1

我想要哈希：

:model => 'opel/corsa'

等等......字符串是可变的，所以这也是有效的：

year<=>2015<br>condition<=>1<br>price<=>2100mileage<=>22000<br>price<=>120000<br>year<=>2012<br>condition<=>2

或者

price<=>656000<br>bathrooms<=>1<br>bedrooms<=>3<br>pets<=>1<br>surface<=>60<br>brokerfree<=>1
model<=>opel/corsa<br>mileage<=>67000<br>vinnumber<=>unknown<br>price<=>145000<br>year<=>2010<br>condition<=>2<br>transmission<=>unknown<br>cartype<=>1

Answer 1

您不需要正则表达式。您可以使用普通红宝石方法。

Answer 2

您也可以使用Array的.to_h方法，请参阅以下示例。

string = "model<=>opel/corsa<br>mileage<=>67000<br>vinnumber<=>unknown<br>price<=>145000<br>year<=>2010<br>condition<=>2<br>transmission<=>unknown<br>cartype<=>1"

hash = string.split('<br>').map{|a| a.split('<=>')}.to_h

## OUTPUT

{"model"=>"opel/corsa", "mileage"=>"67000", "vinnumber"=>"unknown", "price"=>"145000", "year"=>"2010", "condition"=>"2", "transmission"=>"unknown", "cartype"=>"1"}

Answer 3

如果str是您的字符串，您可以按如下方式构建哈希：

Hash[*str.split(/<=>|<br>/)]
  #=> {"price"=>"145000", "bathrooms"=>"1", "bedrooms"=>"3", "pets"=>"1",
  #    "surface"=>"60", "brokerfree"=>"1", "model"=>"opel/corsa",
  #    "mileage"=>"67000", "vinnumber"=>"unknown", "year"=>"2010",
  #    "condition"=>"2", "transmission"=>"unknown", "cartype"=>"1"}

第二个例子：

str = "year<=>2015<br>condition<=>1<br>price<=>2100<br>mileage<=>22000"+
      "<br>price<=>120000<br>year<=>2012<br>condition<=>2"
Hash[*str.split(/<=>|<br>/)]
  #=> {"year"=>"2012", "condition"=>"2", "price"=>"120000", "mileage"=>"22000"}

Ruby正则表达式字符串成为键值对
