正则表达式嵌套的简码不起作用

Question

Can someone tell me why this does not work ? - https://regex101.com/r/hJ5zN6/11

Test string:

[test][dzspgb_container][dzspgb_row][dzspgb_row_part part="1.4"][dzspgb_element text="whwaha" type_element="text"][/dzspgb_element][dzspgb_element text="test" type_element="text"][/dzspgb_element][/dzspgb_row_part][dzspgb_row_part part="1.4"][/dzspgb_row_part][dzspgb_row_part part="1.4"][/dzspgb_row_part][dzspgb_row_part part="1.4"][/dzspgb_row_part][/dzspgb_row][dzspgb_container]test second[/dzspgb_container][/dzspgb_container][/thisbreaks]

Test regex:

*\[dzspgb_container(.*?)](.*?)\[\/dzspgb_container\](?!\s*\[\/)*

If we remove [/thisbreaks] from the string, it will work.

Answer 1

It's because of the negative lookahead assertion at the end. I suggest you to remove that lookahead and use a greedy regex pattern like below.

\[dzspgb_container(.*?)](.*)\[\/dzspgb_container\]

DEMO

(?!\\s*\\[\\/) asserts that the match won't be followed by ( zero or more space characters and a [ symbol )
