[英]Regular expression to extract the first and last number in a string
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? 分别使用这些表达式,我可以从此字符串中提取权重和价格,如何使它在单个组合表达式中起作用?
String: 串:
0.280 Price $ 2.49
Expressions 表达式
(?<weight>\.?\d+(\x2E\d+))
(?<price>\d+\.\d+$)
(?<weight>\.?\d+(?:\x2E\d+)).*?(?<price>\d+\.\d+$)
Try this.See demo. 试试看。看演示。
