VBS TUTORIAL: Introduction to Regular Expressions-common character _vbs

Ordinary characters

Normal characters are made up of all print and nonprinting characters that are not explicitly specified as metacharacters. This includes all uppercase and lowercase alphabetic characters, all numbers, all punctuation marks, and some symbols.

The simplest regular expression is a single ordinary character that matches the character itself in the searched string. For example, the single character pattern ' a ' can match the letter ' a ' that appears anywhere in the searched string. Here are some examples of word single-character patterns:

/a//7//M/

The equivalent VBScript word single-character expression is:

"a""7""M"

You can combine multiple single characters together to get a larger expression. For example, the following Visual Basic scripting Edition Regular expressions are not something else, that is, an expression created by combining single character expressions ' A ', ' 7 ', and ' M '.

/a7M/

The equivalent VBScript expression is:

"a7M"

Please note that there are no connection operators here. All you have to do is put one character behind another character.
