Give us an example of the text you want to match using your regex. We will provide you with some ideas how to build a regular expression.

Case Insensitive

By default, all major regex engines match in case-sensitive mode. If you want patterns such as Name: [a-z]+ to match in case-insensitive fashion, we need to turn that feature on.*

Dot Matches Line Breaks

By default, the dot . doesn't match line break characters such as line feeds and carriage returns. If you want patterns such as BEGIN .*? END to match across lines, we need to turn that feature on.*

Multiline

By default, most major engines (except Ruby), the anchors ^ and $ only match (respectively) at the beginning and the end of the string. In other engines, if you want patterns such as ^Define and >>>$ to match (respectively) at the beginning and the end of each line, we need to turn that feature on.*
