Question

我有这样的输入行：

1 soccer ball at 10
2 Iphones 4s at 199.99
4 box of candy at 50

我想得到第一个数字，项目本身和价格（我不想要＆＃34; at＆＃34;）。

我做了以下正则表达式：

/^(\d+)\sat\s(\d+\.?\d*)$/

但是你可以看到我错过了＆＃34; at＆＃34;之前的内容。我该怎么办？

Answer 1

这应该适合你。

/(\d+)\s+(.+?)\s+at\s+([\d\.,]+)/

Answer 2

这是我的版本：

// double escaped \ as it's supposed to be in PHP
'~(\\d+)\\s+(.+?)\\s+at\\s+(\\d+(?:,\\d+)?(?:\\.\\d+)?)~'
// catches thousands too but stays strict about the order of , and .

干杯！

Answer 3

/^(\d+)\s(.+?)\sat\s(\d+\.?\d*)$/

应该有用。

Answer 4

这里有(\d+)\s([\w ]+)\sat\s(\d+(?:\.\d+)?)
