原标题:Regex to remove all occurances of string only within tags

I need to remove all occurances of a string but only when it is within 2 tags.

例如,在下文的内容中,我需要消除在[禁运][/禁运]标签内出现的oo。

foo
foo
[bar]
foo bar foo
[/bar]
foo

我正在使用PHP,我希望找到一个解决办法,其中涉及两个步骤(即首先在[禁运][/禁运]之间寻找内容,然后取而代之)。 如果不可能做到这一点,那么任何帮助都会受到极大赞赏。

最佳回答

如果你们的政党都组成良好,而且不会nes,你就可以成功地做到这一点。

foo(?=[^[]*[/bar])

检索foo 环绕边界线:> (foo in foobar will not对等),然后是封闭标记[/bar]。 为确保不存在新的开端标一,只与<条码>以外的特性相匹配[和<条码>。

(?=[^[]*[/bar]>) 是 look头说法,只有在内部格局出现时才会看上去。
