The problem is definitely to know exactly what kind of regular expression
jscript supports. There are many flavors: http://www.greenend.org.uk/rjk/2002
/06/regexp.html
That site has a pretty good tutorial. It also includes a RegExp test web page
that allows testing expressions interactively:
http://www.regular-expressions.info/javascript.html
If you like solid paper, this book might help:

Conversation: [Script] Trimming strings
Subject: Re: [Script] Trimming strings
Speaking of regular expressions, can anyone recommend good training materials
or websites for these?
I'm starting to use them more and more as they are wicked fast compared to the
built in jscript String object methods.

var string = "myfilename.0001.jpg"
logmessage (string);
//eg for name
var mynameexp = new RegExp(/\w+/)
var result = string.match(mynameexp)
logmessage (result);
//eg for pad
var mynumexp = new RegExp(/\d{4}/)
var result = string.match(mynumexp)
logmessage (result);
//eg for extension
var result = string.match(/\w+$/)
logmessage (result);
Filesystemobject also has methods for extension etc.

Subject: [Script] Trimming strings
Hello,
Is there are way to trim an string? For instance, I'm getting
a file name. I
would like to compare this name with other file names, but without the
padding and extension (basically to check if there are sequences of
different name in the same folder). The problem is that when
you get the
file name of a file through FileSystemObject, you get the padding and
extensions as well.
Thanks for any info
Bernard
