Regular expression to extract the first and last number in a string

问题

Using these expressions separately, I can extract weight and price from this string, how can I get this to work in a single combined expression?

String:

  0.280    Price $   2.49

Expressions

(?<weight>\.?\d+(\x2E\d+))
(?<price>\d+\.\d+$)

回答1:

(?<weight>\.?\d+(?:\x2E\d+)).*?(?<price>\d+\.\d+$)

Try this.See demo.
