> I often want to call:
> {code:java}
> "OldValue\nOldValue".replaceAll("Regex", "NewValue")
> {code}
> where the old value has end of line chars. So I need to do this:
> {code:java}
> Pattern.compile("Regex", Pattern.DOTALL).matcher("OldValue\nOldValue").replaceAll("NewValue");
> {code}
> which I put in a util methods, which feels like it could be in StringUtils:
> {code:java}
> /**
> * Replaces each substring of the source String that matches the given regular expression
with the given
> * replacement using the {@link Pattern#DOTALL} option. DOTALL is also know as single-line
mode in Perl. This call
> * is also equivalent to:
> * <ul>
> * <li>{@code source.replaceAll("(?s)" + regex, replacement)}</li>
> * <li>{@code Pattern.compile(regex, Pattern.DOTALL).matcher(source).replaceAll(replacement)}</li>
> * </ul>
> *
> * @param source
> * the source string
> * @param regex
> * the regular expression to which this string is to be matched
> * @param replacement
> * the string to be substituted for each match
> * @return The resulting {@code String}
> * @see String#replaceAll(String, String)
> * @see Pattern#DOTALL
> * @since 3.2
