Introduction to VBS regular expressions-order of precedence

Priority order

After a regular expression is constructed, it can be evaluated like a mathematical expression, that is, it can be evaluated from left to right and in a priority order.

The following table lists the order of precedence for various regular expression operators from highest priority to lowest priority:

operator	Description
	Escape character
(), (?:), (?=), []	Parentheses and square brackets
*, +,?, {n}, {n,}, {n,m}	Qualifier
^, $, anymetacharacter	Location and order
|	"or" action
