Question

Let’s say I have the following within my source code, and I want to return only the numbers within the string:

The source is coming from a website, just fyi, and I already have it parsed out so that it comes into the program, but then I need to actually parse these numbers to return what I want. Just having a doosy of a time trying to figure it out tho 🙁

like: 13|100|0;

How could I write this regex?

    var cData = new Array(
        "g;13|g;100|g;0", 
        "g;40|g;100|g;1.37", 
        "h;43|h;100|h;0", 
        "h;27|h;100|h;0", 
        "i;34|i;100|i;0", 
        "i;39|i;100|i;0", 
    );

Answer 1

Not sure you actually need regex here.

var str = "g;13|g;100|g;0";
str = str.Replace("g;", "");

would give you "13|100|0".

Or a slight improvement on spinon’s answer:

// \- included in case numbers can be negative.  Leave it out if not.
Regex.Replace("g;13|g;100|g;0", "[^0-9\|\.\-]", "");  

Or an option using split and join:

String.Join("|", "g;13|g;100|g;0".Split('|').Select(pipe => pipe.Split(';')[1]));
