access vba - What is a Regex equivalent of the 'Trim' function used in languages such as VB and Java..? -


i'm using regex in microsoft access 2007 database vba project reference microsoft vbscript regular expressions 5.5.

all well...mostly. know regular expression act 'trim' function..? (remove leading , trailing spaces)

i have this: ((?:.?)*) "capture after last match". matches spaces remove.

below relevant code, followed screenshot of debugger. item 4 in submatches has " can". how remove space regex, don't have use trim function..?

pattern = "^(\d{1,2})(?:\/)(\d{1,2}(?:\.\d{1,3})?)(oz)((?:.?)*)" regex.pattern = pattern set matchcollection = regex.execute(workstring) if matchcollection.count > 0     matchsection = "loose cases"     itemtype = "case"     percase = matchcollection(0).submatches(0)     perpack = 1     unitsize = matchcollection(0).submatches(1)     uom = matchcollection(0).submatches(2)     other = vba.trim(matchcollection(0).submatches(3)) end if

... debugger

ok, figured out. reiterate (and clarify): original regex ((?:.?)*) meant "capture left after last match". captured leading & trailing spaces.

removing leading spaces easy, every attempt remove trailing spaces foiled * in group. read \b , dropped 1 in , works.

this have now: (?: ?)((?:.?)*)\b(?: *) "match left after last match, except leading or trailing spaces".

and in context, whole of it...

(\d{1,2})/(\d{1,2})pk-(\d{1,2}(?:.\d{1,3})?)(oz|ml)(?: ?)((?:.?)*)\b(?: *)

which meant match on string such this...

2/12pk-11.125oz can ret

...which describes cases of beer in our warehouse. =-)
