[英]Matching specific strings in regex pattern
I have multiple records and I want to match specific strings and at the same time unmatched specific strings.我有多个记录,我想匹配特定的字符串,同时不匹配特定的字符串。 I came up with one pattern but it matches all.
我想出了一种模式,但它匹配所有模式。 Anyone can revise the pattern please?
任何人都可以修改模式吗?
