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。

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])

。 为确保不存在新的开端标一,只与<条码>以外的特性相匹配[条码>和<条码>。
(?=[^[]*[/bar]
>) 是 look头说法,只有在内部格局出现时才会看上去。
