The rule is that the first character, whatever it is, is THE character to
mark beginning and end of the expression.
The following are all the SAME:
"|<[^>]+>(.*)</[^>]+>|U"
"?<[^>]+>(.*)</[^>]+>?U"
"X<[^>]+>(.*)</[^>]+>XU"
/ is a common character to use, but he needed / in his expression, so he
picked | instead.
