Regular expressions

[Arjen]

Hi,

I need some regular expressions but don't know how to create them.
If somebody knows a good, easy to use, readable tool. Please tell me.

I have a textbox.
- The user must enter data. (it may not be empty)
- The data lenght must be between 1 to 255.
- The user may add data on multiple lines. (some lines may be left empty)
- The data is not case-sententive.
- All chars are accepted.

Can someone help me with this one?

Thanks!

I think the only way to seriously work with regular expressions is to
actually learn regular expressions. If you don't understand the principles,
then there' no way for you to tell if the tool is doing what you want (or
sometimes even how to express what you want to the tool).

There's a lot of vagueness here, but I'm think ".{1,255}" satisfies all the
requirements above.

Hi Arjen,

An exellent tool for regexes is this : http://www.regexbuddy.com/

Try this regex ^.{1,255}$ and use the regex with the option "dot matches
newline" otherwise your 3th ristriction isn't covered.

If you use the tool it will explain you what the regex stands for.

Let me know if you have any more questions..

Cheers,
Tom Pester
