Hi,
I''m looking for regular expression that match:sometext \ sometext
text may contain lowercase,uppercase,numbers or special characters
ex:demo-dir\abc123
I''ve tried with this one: ^[a-zA-Z0-9_.-]\\{1,20}$
but not suit exactly.
thanks in advance
推荐答案
^.+\\.+
您可能需要替换."与您的允许的字符"列表:
You may need to replace the "." with your "allowed character" list:
[a-zA-Z0-9_.-]
在"\\"的两侧
我建议您获得一份 Expresso [ ^ ]-它是免费的，可以评估，测试并生成正则表达式.希望我能写！
On both sides of the "\\"
I''d suggest you get a copy of Expresso[^] - it''s free, and it evaluates, tests, and generates Regexes. I wish I''d written it!
