In response to 'No screen name' and ASandstrom on real numbers, the modified answer:

(\+|-)?[0-9]+(\.[0-9]*)?

would highlight

10.

as correct. Here's a minor modifcation to require a digit to the right of the decimal point if one is present:

(\+|-)?[0-9]+(\.[0-9]+)?

hi,

I'd like to use a pattern to check a text field for a correct url.

I found this one, but the browser complains that a ")" is missing. Any ideas how to fix this?

^(http://)([a-zA-Z0-9_\-]+)([\.][a-zA-Z0-9_\-]+)+([/][a-zA-Z0-9\~_\-]*)+([\.][a-zA-Z0-9_\-]+)*$

thanks,
markus

With respect to the post by switchbox:
We should either delete the example or change it substantially.
The example only matches a URL parameter name, er, named, "value" and does not include the parameter value.

[\?&]value=

Should say [\?&]attribute=

URL parameters are attribute=value pairs.

You are correct. The documented regular expression finds 0.12, for example, but at the wrong location in the string.
You can test it with the following:

The real number starts at position 10.

The result is of the documented regular expression is #resultoffindMM#.

The result of the proposed regular expressin is #resultoffindALT#.

Thanks for the feedback!

Should not the regular expression for 'real' values be something like:

(\+|-)?[0-9]+(\.[0-9]*)?

Otherwise, values like '0.12' will not be found, I guess.

[A-Za-z][A-Za-z0-9_]* = A ColdFusion variable with no qualifier.

This is incorrect as it only matches the first character (using REFind).

The correct expression is:

^[A-Za-z][A-Za-z0-9]*$
