Trouble using Regex Inside VBscript

I am trying to identify and store a date/time value in a string. This string will be read from another file. I am trying to identify the date/time and then store it in a variable using regex and vbscript. I want to identify date/time in mm/dd/yy hh:mm:ss am|pm|AM|PM.

Here is the regex that does it:
^(([0]?[1-9]|1[0-2])/([0-2]?[0-9]|3[0-1])/[0-9]\d{1})? ?((([0-1]?\d)|(2[0-3])):[0-5]\d)?(:[0-5]\d)? ?(AM|am|PM|pm)?$

Open in new window


Here is an example of one line from the document where I want to identify the date/time from:
3400,CONTROLLER IN SLOT A,6531,97.8,84.6,30893.5,30893.5,1088.5,1088.5,Date/Time: 11/12/10 2:28:52 PM

Open in new window


Here is my test code:
Set myRegExp = New RegExp
myRegExp.IgnoreCase = True
myRegExp.Global = True
myRegExp.Pattern = "^(([0]?[1-9]|1[0-2])/([0-2]?[0-9]|3[0-1])/[0-9]\d{1})? ?((([0-1]?\d)|(2[0-3])):[0-5]\d)?(:[0-5]\d)? ?(AM|am|PM|pm)?$"
strToSearch = "3400,CONTROLLER IN SLOT A,6531,97.8,84.6,30893.5,30893.5,1088.5,1088.5,Date/Time: 11/12/10 2:28:52 PM"

Set myMatches = myRegExp.Execute(strToSearch)
For Each myMatch in myMatches
  msgbox myMatch.Value, 0, "Found Match"
Next

Open in new window

So ideally, I want to use this to look at each line in the txt document in question, and set a variable to the identified date/time value. This will then later be used for insert purposes into a sql table. I am struggling trying to get the date time value to be recognized correctly within the string. If you take off the explicit indicators (^ and $) on the regex every individual character comes up as a match but so does the exact string I am looking for. If I use the explicit indicators nothing in the string matches.

All help is welcome! Thanks in advance!

Try this modification:
Set myRegExp = New RegExp
myRegExp.IgnoreCase = True
myRegExp.Global = True
myRegExp.Pattern = "(1[012]|0?[1-9])/(3[01]|[012]\d)/\d{2} ?(1[012]|0?[1-9])(:([1-5]\d|0?\d)){2}"
strToSearch = "3400,CONTROLLER IN SLOT A,6531,97.8,84.6,30893.5,30893.5,1088.5,1088.5,Date/Time: 11/12/10 2:28:52 PM"

Set myMatches = myRegExp.Execute(strToSearch)
For Each myMatch in myMatches
  msgbox myMatch.Value, 0, "Found Match"
Next

Perhaps that last zero shouldn't be optional  :)
(1[012]|0?[1-9])/(3[01]|[012]\d)/\d{2} ?(1[012]|0?[1-9])(:([1-5]\d|0\d)){2}

Haha, shoot. Is that what that means? I am new to regex. I was close though right? Thanks a bunch.

I learned from this site:  http://www.regular-expressions.info . They have a breakdown for several different languages.

In case anyone is interested the exact match looks like this:
(1[012]|0?[1-9])/(3[01]|[012]\d)/\d{2} ?(1[012]|0?[1-9])(:([1-5]\d|0\d)){2}?(:[0-5]\d)? ?(AM|am|PM|pm)?

That matches the following format:
mm/dd/yy hh:mm:ss AM|PM|am|pm

I'm sorry... I completely forgot about the AM|PM part. I had it in my original attempt at your query, but then I rewrote it and forgot to put that in.
