Javascript - regex only catches the first 3 matches -

first, in advance can provide.

my regex capturing first 3 instances of string i'm trying extract. ideas?

my code:

var objargs         = wscript.arguments; var objfilesys      = new activexobject("scripting.filesystemobject"); var objfolder       = objfilesys.getfolder(objargs.item(0)); var objtsetnum      = new regexp("^st.((\\d+)+)", "gm"); var objfile         = null; var srcfile         = null;  (var objfileenum = new enumerator(objfolder.files); !objfileenum.atend(); objfileenum.movenext()) { objfile = objfilesys.opentextfile(objfileenum.item(), 1, false, 0); srcfile = objfile.readall(); objfile.close();  // check different values in tset entries // build array hold tset values found var arrtset; while ((arrtset = objtsetnum.exec(srcfile)) !== null) {     // arrtset = objtsetnum.exec(srcfile);     wscript.echo("arrtset is: " + arrtset);     wscript.echo("length of arrtset is: " + arrtset.length)     //var alltsetsame = true; } 

and sample text file has 5 instances of line beginning "st*" - shouldn't 5 placed array?:

isa*00*          *00*          *01*041199639      *08*9272590000     *150704*1131*u*00401*000001324*0*p*: st*865*0001 st*865*0001 st*865*0001 st*865*0001 st*865*0001 iea*5*000001324 

any advice? hunch telling me exec() function changing something, can't find details might changing.

appreciate help!

edit: of course, once posted it, found answer. exec() stateful, needed push each result returned array, similar to:

var arrtset = []; var match;      while (match = objtsetnum.exec(srcfile)) {     arrtset.push(+match[1]);             } 

which found here (giving credit): why javascript's regex.exec() not return same value?

what think problem might regexp.exec doesn't return array of possible results, returns first result matches in result. if through array back, matches be:

1. st*865
2. 865
3. 865

exec continue return next match each time call it
