regular expression.
Note
Calling this method does not move the current position to the location where the match
occurred. This allows you to use the method as a look-ahead function without disrupting
the rest of the data mapping workflow.

flags
i: Enables case-insensitive matching. By default, case-insensitive matching assumes that
only characters in the US-ASCII charset are being matched. Unicode-aware case-insensitive
matching can be enabled by specifying the UNICODE_CASE flag (u) in conjunction with this
flag.
s: Enables dotall mode. In dotall mode, the expression . matches any character, including a
line terminator. By default this expression does not match line terminators.
L: Enables literal parsing of the pattern. When this flag is specified, then the input string that
specifies the pattern is treated as a sequence of literal characters. Metacharacters or escape
sequences in the input sequence will be given no special meaning. The CASE_
INSENSITIVE (i) and UNICODE_CASE (u)flags retain their impact on matching when used
in conjunction with this flag. The other flags become superfluous.
m: Enables multiline mode. In multiline mode, the expressions ^ and $match just after or just
before, respectively, a line terminator or the end of the input sequence. By default, these
expressions only match at the beginning and the end of the entire input sequence.
u: Enables Unicode-aware case folding. When this flag is specified, then case-insensitive
matching, when enabled by the CASE_INSENSITIVE flag (i), is done in a manner consistent
with the Unicode Standard. By default, case-insensitive matching assumes that only
characters in the US-ASCII charset are being matched.
U: Enables the Unicode version of Predefined character classes and POSIX character
classes. When this flag is specified, then the (US-ASCII only) Predefined character classes
