Hi All,

Need help with regular expression to check for form input  which is in following criteria.

A (numeric) (numeric) (numeric) (numeric) (alpha) - [aA]\d{4}[a-zA-Z] - example A1234Z

System should accept anything other that String A1234Z, i tried this but didnot work

!([aA]\d{4}[a-zA-Z])

Any help is helpful.

Thanks.

Why does your attempt have an exclamation point?

I think he might be using the exclamation mark in the sense that some programming languages use it: 'not' as in logical negation.

As for the possible solution (lacking any knowledge of the regex/langauge/paltform etc (OP - please read the posting guidelines in the sticky note at the strat ofm this forum)), try:

^(?!A\d{4}[a-z]$).*$

with the 'ignore case' option on, which will accept anything other than the pattern in the lookahead.

Of course, if this is embedded in a programming language, then you could do something like the following pseudo-code:

regexExpression re = regexMatch("[aA]\d{4}[a-zA-Z]")
if( !re.matchesTheText(someText))
then
    do something knowing that someText does NOT match the pattern
end

I think this is what the OP was thinking about.
