RegEx to extract a name after a string is found in a string

Question

I am trying to check if a string is in a string using RegEx in a AutoHotKey script.

If my string is a file path like this:

G:\htdocs\projects\webdevapp\app\folder\file.php

Then I need to extract the webdevapp part.

From the AutoHotKey docs it gives this example for a RegEx command that will store the found value to a variable:

; Returns 1 and stores "XYZ" in SubPat1.
FoundPos := RegExMatch("abcXYZ123", "abc(.*)123", SubPat)  

So in theory something similar to this below except the regex part would need to be changed...

FoundPos := RegExMatch("G:\htdocs\projects\webdevapp\app\folder\file.php", "G:\htdocs\projects\(.*)\app\folder\file.php", DomainNameVar)  

Any help in extracting that domain name from the file path into a variable in AutoHotKey?

It basically need to check if the string starts with G:\htdocs\projects\ and if it does then grab any character after that point until it comes up to the next \

Answer 1

I got it!

FoundPos := RegExMatch("G:\htdocs\projects\webdevapp\app\folder\file.php", "G:\\htdocs\\projects\\([^\\]+)*", DomainNameVar) 

G:\\htdocs\\projects\\([^\\]+)*
