I have tried to match <b> using regular expressions.
the pattern /<.>/ matches <b> but the pattern /<[.]>/ does not match.
What is the difference between /<.>/ and /<[.]>/ in regular expressions

A dot is a metacharacter matching almost any symbol only outside character classes (bracket expressions in POSIX terminology). – Wiktor Stribiżew Jul 28 '16 at 05:48

When you put dot inside [] it is a literal dot, not a any character.
So the /<[.]>/ matches only <.>. It is the same as escaping a dot: \. in regexp.
