replaceAll

text replaceAll(text, regex, replacement)

Replaces each substring in text that matches the regular expression with the given replacement.

The replacement text may contain $1..$N references to capture groups declared within the regular expression.

Both the regular expression syntax and text literals use the backslash \ and left curly bracket { characters for special purpose. Use \\ and \{ to avoid the text literal interpretation.

Flags embedded as a prefix in regex:
