问题描述
我的内容带有<del></del>和<ins></ins>标记.我有一个正则表达式，可以满足图片中清楚说明的条件
I have a content with <del></del> and <ins></ins> tags. I have a regex which satisfies the conditions which are clearly explained in the image

满足条件的正则表达式是
The regex which satisfies the conditions is

此正则表达式运行正常.但是，当内容更多或匹配内容很长时，执行时间会增加，从而引发超时错误，该错误可在regex101.com/r/cE4mE3/20
This regex is working perfectly fine. But, when the content is more or When the matching content is long the execution time is increasing and hence throwing a timeout error which can be seen in regex101.com/r/cE4mE3/20
如何简化正则表达式(\w*(?:(?:(?:<del\b[^>]*>(?:(?!<\/del>).)*<\/del>)|(?:<ins\b[^>]*>\w+<\/ins>)|(?:\w+<\/ins>)|(?:<ins\b[^>]*>\w+))(?:\w+|))+)以避免引发超时错误
How to simplify the regex (\w*(?:(?:(?:<del\b[^>]*>(?:(?!<\/del>).)*<\/del>)|(?:<ins\b[^>]*>\w+<\/ins>)|(?:\w+<\/ins>)|(?:<ins\b[^>]*>\w+))(?:\w+|))+) to avoid it from throwing timeout error
推荐答案
正则表达式不是正确的方法.您自己发现了一个陷阱.还有更多.因此请切换到DOM分析器.要消除超时问题，您可以尝试
Regex is not correct way to do this.You yourself have discovered a pitfall.There will be more.So switch to DOM parser .As for removing the timeout issue , you can try
((?=(\w*))\2(?:(?:(?:<del\b[^>]*>(?:(?!<\/del>).)*<\/del>)|(?:<ins\b[^>]*>\w+<\/ins>)|(?:\w+<\/ins>)|(?:<ins\b[^>]*>\w+))(?:\w+|))+)
