正则表达式仅检测特殊字符之间的数字

Question

I need Regex to detect numbers only between special characters.

Pattern ;\\d+=\\d+?

String 0014;5010730101000033347=4510120173?AA

My objective is to get this string

;5010730101000033347=4510120173?

Answer 1

The \\d+? at the end of the pattern matches 1 digit, no more, due to the +? lazy quantifier matching 1 or more occurrences, but as few as necessary to return a valid match .

You may use

;\d+=\d+\?
        ^^

C# declaration:

string pattern = @";\d+=\d+\?";

See the regex demo

Details :

• ; - a semi-colon
• \\d+ - 1 or more digits
• = - an equal sign
• \\d+ - 1 or more digits
• \\? - a literal ? char
