C# C# Regex Help? Using an integer to search through regex?

[TheUninvited]

We have this text:

<snippet>

<content><![CDATA[

${1:first}, ${2:second} ${3:second}

]]></content>

   <!-- Optional: Set a tabTrigger to define how to trigger the snippet -->

<tabTrigger>2p</tabTrigger>

  <!-- Optional: Set a scope to limit where the snippet will trigger -->

   <!-- <scope>source.python</scope> -->

</snippet>

I want to grab this elements and add them to a list is my goal but only add them in the list if the number exist , the elements could be 4 or 5 or 10 it doesn’t matter…

${1:first}
${2:second}
${3:second}

we use this command of regex to grab them :

Regex myRegex = new Regex(@"`(\${)(.*?)(?=})");

and somehow i want to use a counter like to search through , i want something like this ,but i know is not possible because it doesn’t work exactly like that…so any ideas how can i do that in c#? or in general ?

int num;
Regex myRegex = new Regex(@"(\${num)(.*?)(?=})");

alright man no problem basically i have another problem.

So the thing is i used this code to find my value and it does:

int num = 1;


Regex subMarks = new Regex(@"(\${)" + num + @"(.*?)(?=})");
            Match matchsubMarks = subMarks.Match(subInText);
            
    if(matchsubmarks.Success)       
int++;

using the num as an increment but the value does not updates in the regex even though the num goes to number 2.

It supposed to find
${2:second}

but nope...

Well, you are starting with num = 1, and then you are incrementing int++, instead of num++
Shouldn't that say num++ ?
And is the submarks value / matchsubmarks inside a loop so that the incremented number is used?

I modified your regex to Regex maxReg = new Regex(@"(\${)\d+(.*?)(?=})");. Maybe this can help.

what do you mean ? I am looking for a way not to rewrite my code twice . just check out the code the info is inside.

yeah, there's a lot of repeated code in your link. I'm guessing you'll want one Regex object that can take in a string and get a collection of matches?
