Let's say I have this text:

"""xsdsdsds\ncat xsdhidhf"""

and my regex is:

val myRegex = "\b(?i)cat\b"

This doesn't recognize that the text above has the word cat in it because its tied to the \n character.

How can I change the regex to find a word as a whole (with spaces from both sides) but ignore the \n?

CodePudding user response：

You can use

val myRegex = """(?i)(?<=\b|\\n)cat\b"""

Details:

• (?i) - case insensitive matching on
• (?<=\b|\\n) - either a word boundary or a \n text must appear immediately on the left
• cat - a string cat
• \b - a word boundary.

See the regex demo.
