正则表达式为欧元金额

Question

我需要找到一个只选择金额（以欧元为单位）的正则表达式，因此该值需要以€或euros开头，并且在,之后我们有便士，也可以有空格或点。

7 967  59 €
- 9847, 48 euros à titre de rappel de salaire sur le bonus de l'année 2012,
 - 1929, 78 euros à titre de rappel de salaire sur le bonus de l'année 2013,

我想出了这个：

(\d.+\d+)(?:\s(?:euros?|€))

但它并不准确。

有人能帮帮我吗？

编辑：

@WiktorStribiżew给了我：

(\d[\d.\s,]*)(?:\s(?:euro|€))

虽然很接近但有这个例子：

2014,7 967, 59 €

它也需要2014,

和49715 11000158926 101,30 €

需要49715 11000158926。数字仅限于3人。

和2007 3.708,34 €

它也不应该取2007

编辑2：

感谢您的回答，但似乎无法在我的python脚本中运行：

import regex
sentences_pd = pd.read_csv('sampled_amounts.csv', names=["text"])
sentences_pd.head()
print([(regex.findall("\b((?:\d+|\d{1,3}(?:[,.\s]\d{3})*)(?:[,.\s]*\d+)?)\s(?:euros?|€)", x)) for x in sentences_pd['text']])

文本列如下所示：

它给了我一个空数组

[[], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], []]

Answer 1

您可以使用

\b((?:\d+|\d{1,3}(?:[,.\s]\d{3})*)(?:[,.\s]*\d+)?)\s(?:euros?|€)

请参阅regex demo

<强>详情

• \b - 字边界
• ((?:\d+|\d{1,3}(?:[,.\s]\d{3})*)(?:[,.\s]*\d+)?) - 第1组
  • (?: - 一个轮换组开始
    • \d+ - 1+位数
    • | - 或
    • \d{1,3} - 1至3位数字
    • (?:[,.\s]\d{3})* - 0+序列
      • [,.\s] - 1个空格，,或.
      • \d{3} - 3位数
  • ) - 交替小组结束
  • (?:[,.\s]*\d+)? - 可选组
    • [,.\s]* - 0+个空格，,或.
    • \d+ - 一位或多位
• \s - 空白
• (?:euros?|€) - euro，euros或€

Answer 2

如果有帮助，我以西班牙价格（€）创建了此Regex。条件是：

1.- The decimal point with 2 exact decimals
2.- Decimals can not be "00"
3.- The point of a thousand is not admitted. In my case the prices do not exceed 999 €
4.- The front and back spaces are not allowed
5.- One ¨0¨ is not admitted in front of a whole number

Regex: ^((0\,(?!00)\d{2})|([1-9]\d*(\,(?!00)\d{2})?)|0)$

允许的值：

• 0
• 1234
• 0,10
• 12,34

不允许的值：

• 0,00
• 0,1
• 1234（开头的空格）
• 1234（末尾有空格）
• 12,00
• 01,23
• 12,345
• 1.234
