regex - Regular expression that matches when a character is in between two characters, but the inner character can be one of the outer delimiters

Question

I have a string like this:

<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>

and I want a Regex that will match whenever there's a situation like this:

<https://example.com/code/INSTRUMENTS/AGD<1>
<https://example.com/code/INSTRUMENTS/AGD>1>

to detect such invalidly serialized IRIs (similar to URIs/URLs).

I've looked at existing answers on SO, but none of them seem to work when the inner character is the same as one of the outer characters.

Answer 1

假设<总是必须用 a 关闭>并且它们不能“嵌套”：

(<[^>]*<|>[^<]*>)

如果它只是关于布尔检查/验证，这将检测到它们。

如果您还想捕获完整的字符串

(<[^>]*<[^<]*>|<[^>]*>[^<]*>)

（希望没有错别字）
