\s Matches a space, non-breaking space, tab, line
ending, or other white space character.
Tip: Many languages do not se
parate words
with white space. Even in languages that
usually use a white space separator, words can
be separated with many other characters such
as:
\/-”’"“‘.,><—:;
and new lines.
In these cases, you should usually include
th
ose in addit
ion to \s in a match set ( [] ) or
may need to use \b (word bo
undary) instead.

href=‘ht
tp://www.example.com’
