Non capturing group getting captured in full match

Question

Sample string: dadasd_37=12abc_dadasd_asdasdasd_asdas_asd
My regex: (?:_37=)([^_]+)
What i am trying to get: 12abc (anything that starts with 37= and the word ends with _).

However, the full match is still coming as _37=12abc

"the word ends with _" That's not doing this *at all*. All `([^_]+)` is going is capture anything that isn't a `_` — math2001, Feb 19 '17 at 07:39
Not an expert on regex but this pattern is doing what i want ... well very similar to what i want — Pankaj Jaju, Feb 19 '17 at 08:21

Capturing group matches are accessed via the SubMatches collection.

<%
Dim regex, matches, match, strSubject, strResult

strSubject = "dadasd_37=12abc_dadasd_asdasdasd_asdas_asd"

set regex = new RegExp
regex.IgnoreCase = True
regex.Pattern = "(?:_37=)([^_]+)"

set matches = regex.Execute(strSubject)

if matches.Count >= 1 then
    set match = matches(0)
    if match.SubMatches.Count >= 1 then
        strResult = match.SubMatches(0)
    else
        strResult = ""
    end If
else
    strResult = ""
end if

response.write "strResult:" & strResult & ""
%>

Is there a way that I only get the required text so that I don't have to process the sub matches – Pankaj Jaju Feb 19 '17 at 07:23
I don't know of any other way with vbscript. – Kevin Collins Feb 19 '17 at 07:35
Can you use javascript instead? http://stackoverflow.com/a/432503/989516 – Kevin Collins Feb 19 '17 at 07:38
