无效。

它告诉我一个错误：

正则表达式中的语法错误。



请帮助....

如果你想要像2013/12/25这样的日期格式的正则表达式，试试这个

（\d）{4}（\ /）（[0] [1-9] | [1] [012]）（\ /）（[0] [ 1-9] | [12] [1-9] | [3] [01]）

要在代码中使用它，请说java，javascript或c＃，你将不得不用'\'来逃避'\'。ockquote>

你的实际正则表达式工作正常，如果我把它送到Expresso它甚至可以工作 - 问题是字符串分隔符。你用'/'分隔了字符串，但你的字符串也包含'/'字符，它们将作为字符串的结尾....如果你使用不同的字符串分隔符（例如双引号），它应该可以正常工作。

If you want regex for date format like 2013/12/25, try this

(\d){4}(\/)([0][1-9]|[1][012])(\/)([0][1-9]|[12][1-9]|[3][01])

To use this in your code say java, javascript, or c#, you will have to escape the '\' with '\'.

Your actual Regex works fine, if I feed it into Expresso it even works - the problem is the string delimiters. You have delimited the string with '/' but your string also contains '/' characters, which will act as the end of the string.... If you use a different string delimiter (double quotes for example) it should work fine.
