Troubleshooting Code 800A139B - Expected ']' in regular expression
Introduction to Error Code 800A139B
This error code, 800A139B occurs when you attempting to perform a regular expression search.
My suggestion is that there is syntax error in a complex pattern.
The Symptoms You Get 800A139B
The script does not execute as you hoped, instead you get a WSH error message.Category: Microsoft VBScript runtime Description: Expected ']' in regular expression Number: 0x800A139B (-2146823269)
The Cause of Error 800A139B
The underlying cause is a syntax error, in the sense that you are missing a closing bracket. With this error pay close attention to what comes next after: Description: Expected..............
In this example the script is looking for a closing bracket ']', and not an opening bracket. This was the example:
Problem "\<[\w+\]>"

The Solution
Stephen Gentry kindly sent in both the problem and this solution. From what I gather, Stephen is trying to execute sophisticated pattern matching code:
Correct syntax "<\[\w+\]>" and
"\<\[\w+\]>"
While I have not studied the escape character in this sequence, it seems to me that a backslash acts as an escape character. thus \<[ does not escape the [ (it escapes the <.
In this example: "<\[\w+\]>"
Both the opening and closing bracket are escaped by the backslash \[ and later \]. This is why the solution works, and why the problem complains about an expected
closing bracket.
