问题描述

更新：目前，已经实现了一个可以同时使用多个正则表达式的工作解决方案

Update: Currently, a working solution has been achieved with multiple regular expressions used simultaneously

我'我正在寻找一个涵盖ISO 8601日期可接受语法范围的正则表达式。大多数库和正则表达式仅涵盖8601的子集或简化版本，例如RFC 3339，但完整的8601包括表达持续时间和间隔的方式。 ISO 8601的维基百科条目提供了一个很好的概述，但简而言之，这些都应该是有效的日期：

I'm looking for a regular expression that covers the range of acceptable syntax for ISO 8601 dates. Most libraries and regex's only cover a subset or a "simplified" version of 8601, such as RFC 3339, but the full 8601 includes ways to express time durations and intervals. The wikipedia entry for ISO 8601 provides a good overview, but in short these should all be valid dates:

var testDates = {
    'year' : "2013",        
    'date' : "2013-01-05",
    'datetime' : "2013-01-05T04:13:00+00:00",
    'Duration only' : "P1Y2M10DT2H30M",
    'Week Duration' : "P1W",
    'Range with start and end' : "2007-03-01T13:00:00Z/2008-05-11T15:30:00Z",
    'Range of Date/Duration' : "2007-03-01T13:00:00Z/P1Y2M10DT2H30M",
    'Range of Date/Duration 1 month' : "2012-10/P1M",
    'Range of Date/Duration 1 week' : "2012-10/P1W",
    'Range of Duration/Date' : "P1Y2M10DT2H30M/2007-03-01T13:00:00Z", 
    'Repeating interval 5 times' : "R5/2007-03-01T13:00:00Z/P1Y2M10DT2H30M", 
    'Repeating interval weekly indefinitely' : "R/2012-10/P1W",
    'Repeating interval monthly 5 times' : "R5/2012-10/P1M"
}

我正在尝试构建一个涵盖所有这些可能性的正则表达式。我已经将几个组件拼凑在一起，但是对于正则表达式并不熟练，使它们都可以作为一个表达式工作并覆盖所有可能的情况。只是在这些之间做一个简单的OR似乎没有按预期工作，但也许我做得不对。

I'm trying to build a regular expression that will cover all these possibilities. I've pieced a few components together, but am not skilled enough with regular expressions to make them all work as one expression and cover all possible cases. Just doing a simple "OR" between these doesn't seem to work as expected, but perhaps I'm not doing it quite right.

我尝试过的表达式包括：

The expressions I've tried include these:

var regex = {
    'Date' : /^([\+-]?\d{4}(?!\d{2}\b))((-?)((0[1-9]|1[0-2])(\3([12]\d|0[1-9]|3[01]))?|W([0-4]\d|5[0-2])(-?[1-7])?|(00[1-9]|0[1-9]\d|[12]\d{2}|3([0-5]\d|6[1-6])))([T\s]((([01]\d|2[0-3])((:?)[0-5]\d)?|24\:?00)([\.,]\d+(?!:))?)?(\17[0-5]\d([\.,]\d+)?)?([zZ]|([\+-])([01]\d|2[0-3]):?([0-5]\d)?)?)?)?$/,

}

我整理了一个尝试的示例脚本这些表达式在上面列出的每个日期，但如果有人可以提供将所有这些案例组合成一个表达式的指导，那将非常感激。

I've put together an example script that tries these expressions on each of the dates listed above, but if anyone could provide guidance on combining all these cases into one expression, it would be much appreciated.

推动此操作的用例是验证JSON Schema文档的ISO 8601日期。 JSON Schema确实提供了一些灵活性，可以验证某些内容，因为您可以提供多个规则或正则表达式来进行测试。在这种情况下，我可以通过使用多个正则表达式而不是一个组合表达式来解决我的问题。

The use case that's driving this is to validate an ISO 8601 Date for a JSON Schema document. JSON Schema does provide some flexibility in how something is validated in that you can provide multiple rules or regular expressions to test. In this case, I could solve my problem by using multiple regular expressions rather than one combined expression.

更新：到目前为止，使用此方法解决了这个问题（同时使用多个单独的表达式）

Update: the problem has been addressed so far by using this approach (multiple separate expressions used simultaneously)

推荐答案

这是我发现的完整的表达式，可以实现各种ISO 8601语法。 要点已针对重复间隔进行了这些和其他测试的更新。

Here's the full set of expressions I've found to achieve the variety of ISO 8601 syntax. The gist has been updated with these and additional tests for repeating intervals.
