Question

I’m trying to parse through an mht (text) file and extract just certain lines.
RegExMatch is working just fine to do that.
However, inside my loop, I want to strip away EVERYTHING from those particular lines except the 7 digit string which consists of the letter “E” followed by 6 digits.

Here is my latest failed attempt.
This clown clearly doesn’t know much RegEx.

Help?

Thanks

If RegExmatch(A_LoopReadLine,"E\d\d\d\d\d\d")
    {
    ECode := RegExReplace(A_LoopReadLine, "^[Ed\d\d\d\d\d\d]", "")
    FileAppend, %ECode%., G:\2013.txt
    }

Answer 1

It should be

 RegExReplace(A_LoopReadLine, "^.*(E\d{6}).*$", "$1")

\d{6} represents 6 digits..{} is a quantifier..so {n} means match preceding character n times

() represents a group..so everything which is captured within the group can be referenced through $n where n is the group no.
