使用ruby从数据中获取特定值

Question

attributes = query(View").first["description"]

puts attribute打印以下值

 "description" => "android.widget.ImageView{b10b2c28 V.ED..C. .....
I. 880,0-1760,672}

从这里我必须得到值880

从以下值开始，我必须打印值1760.

"description" => "android.widget.ImageView{b17b03c8 V.ED..C. ......
I. 1760,96-2832,576}
