Regex Validator anomaly in IE
Hi
I've set up a RegularExpressionValidator on a password input.
The Expression is ^(?=\D*\d)(?=[^a-zA-Z]*[a-zA-Z])[\da-zA-Z]{6,20}$ which should match a string of length 6-20 that contains a mixture of numbers and letters (no punctuation).
This is fine in Regulator (a regex generating tool), and Mozilla Firefox, but in IE6, it doesn't match what should be valid strings ("aaaaa1" for example).
Does the regex engine in IE not support the ?= (positive lookahead) regex syntax?
