I’m a licensed xbench user ([hyang@acclaro.com](mailto:hyang@acclaro.com)). However, a regular expression that works in other tools doesn’t work in xbench. Would you check it for me?

Source: (?i)(\b(not|no)\b)|(n[‘’]t\b)  
Target: (?i)(?m)^((?!(?i)(外|出乎|难|以后再|空|数|号|取消|不|无|非|未|否|没|勿|别|失|只|仅|防止|避免|防|禁止|以外的|直到.+?才|以免|莫|除.+?外|无论|是否|难以|违背|违反|尽管|随时|错误|续|欠|缺|停|止|杜绝|极|必须\*.+才|但|超出|(\b(no|not)\b)|(n[’’]t\b))).)\*\r?$

Regex syntax is different from the one in your sample. For more information about xbench regex syntax, look at [Regular Expressions and Microsoft Word Wildcards :: ApSIC Xbench Documentation](https://docs.xbench.net/user-guide/regular-expressions/#regular-expressions-syntax) and [Special Sets :: ApSIC Xbench Documentation](https://docs.xbench.net/user-guide/special-sets/).
