Email RegEx is taken from the RegEx Buddy library and comes with the following provisos -

电子邮件RegEx取自RegEx Buddy图书馆，附带以下附带条件 -

Does not match email addresses using an IP address instead of a domain name.

与使用IP地址而不是域名的电子邮件地址不匹配。

Does not match email addresses on new-fangled top-level domains with more than 4 letters such as .museum. Including these increases the risk of false positives when applying the regex to random documents.

与超过4个字母的新奇*域名上的电子邮件地址不匹配，例如.museum。在将正则表达式应用于随机文档时，包括这些会增加误报的风险。
