VBScript - RegEx - modify ObjMatch - Pattern = "(\d{2}) (\d{2}) (\d{2})" -

this stumbled across while trying learn little reg ex.

set objregex = createobject("vbscript.regexp") dim re, targetstring, colmatch, objmatch set re = new regexp re .pattern = "(\d{2}) (\d{2}) (\d{2}) 0500z" .global = true .ignorecase = true end  targetstring = "02 04 14 0500z joe eating sandwich"  set colmatch = re.execute(targetstring) each objmatch  in colmatch wscript.echo objmatch  date1 = objregex.replace(objmatch, "(\d{2})(\d{2})(\d{2})") wscript.echo date1 

issue: need find date shows "02 04 14 0500z" , assign variable in form "020414".

when try replace obj match , reformat date doesn't work, instead showing exact text in brackets.

to refer content captured capturing group, use $n in replacement string (where n number):

date1 = re.replace(objmatch, "$1$2$3") 

to identify number of capturing group, count number of opening parentheses ( belongs capturing group capturing group want refer to:

(\d{2}) (\d{2}) (\d{2}) 0500z ^       ^       ^ 1       2       3

a more complicated example:

((a(?:k)*)(b(c)(?:d)*)) ^^        ^ ^ 12        3 4 

(?:pattern) non-capturing group, doesn't count.
